  • ‘If Exercise Could Cure This, I Would Have Been Cured So Quickly’

    ‘If Exercise Could Cure This, I Would Have Been Cured So Quickly’

    In the weeks after she caught COVID, in May 2022, Lauren Shoemaker couldn’t wait to return to her usual routine of skiing, backpacking, and pregaming her family’s eight-mile hikes with three-mile jogs. All went fine in the first few weeks after her infection. Then, in July, hours after finishing a hike, Shoemaker started to feel off; two days later, she couldn’t make it to the refrigerator without feeling utterly exhausted. Sure it was a fluke, she tried to hike again—and this time, was out of commission for months. Shoemaker, an ecologist at the University of Wyoming, couldn’t do her alpine fieldwork; she struggled to follow a movie with a complex plot. She was baffled. Exercise, the very thing that had reliably energized her before, had suddenly become a trigger for decline.

    For the majority of people, exercise is scientifically, physiologically, psychologically good. It boosts immunity, heart function, cognition, mood, energy, even life span. Doctors routinely prescribe it to patients recovering from chronic obstructive pulmonary disease and heart attacks, managing metabolic disease, or hoping to stave off cognitive decline. Conditions that worsen when people strive for fitness are very rare. Post-exertional malaise (PEM), which affects Shoemaker and most other people with long COVID, just happens to be one of them.

    PEM, first described decades ago as a hallmark of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), is now understood to fundamentally alter the body’s ability to generate and use energy. For people with PEM, just about any form of physical, mental, or emotional exertion—in some cases, activities no more intense than answering emails, folding laundry, or digesting a particularly rare steak—can spark a debilitating wave of symptoms called a crash that may take weeks or months to abate. Simply sitting upright for too long can leave Letícia Soares, a long-hauler living in Brazil, temporarily bedbound. When she recently moved into a new home, she told me, she didn’t bother buying a dining table or chairs—“it just felt useless.”

    When it comes to PEM, intense exercise—designed to boost fitness—is “absolutely contraindicated,” David Putrino, a physical therapist who runs a long-COVID clinic at Mount Sinai, in New York, told me. And yet, the idea that exertion could undo a person rather than returning them to health is so counterintuitive that some clinicians and researchers still endorse its potential benefits for those with PEM; it’s dogma that Shoemaker heard repeatedly after she first fell ill. “If exercise could cure this,” she told me, “I would have been cured so quickly.”

    The problem is, there’s no consensus about what people who have PEM should do instead. Backing off physical activity too much might start its own downward spiral, as people lose muscle mass and strength in a phenomenon called deconditioning. Navigating the middle ground between deconditioning and crashing is “where the struggle begins,” Denyse Lutchmansingh, a pulmonary specialist at Yale, told me. And as health experts debate which side to err on, millions of long-haulers are trying to strike their own balance.

    Though it’s now widely accepted that PEM rejiggers the body’s capacity for strain, scientists still aren’t sure of the precise biological causes. Some studies have found evidence of impaired blood flow, stymieing the delivery of oxygen to cells; others have discovered broken mitochondria struggling to process raw fuel into power. A few have seen hints of excessive inflammation, and immune cells aberrantly attacking muscles; others point to issues with recovery, perhaps via a slowdown in the clearance of lactate and other metabolic debris.

    The nature of the crashes that follow exertion can be varied, sprawling, and strange. They might appear hours or days after a catalyst. They can involve flu-like coughs or sore throats. They may crater a patient’s cognitive capacity or plague them with insomnia for weeks; they can leave people feeling so fatigued and pained, they’re almost unable to move. Some of Shoemaker’s toughest crashes have saddled her with tinnitus, numbness, and extreme sensitivity to sound and light. Triggers can also change over time; so can people’s symptoms—even the length of the delay before a crash.

    But perhaps the worst part is what an accumulation of crashes can do. Rob Wüst, who studies skeletal-muscle physiology at Amsterdam University Medical Center, told me that his team has found an unusual amount of muscle damage after exertion in people with PEM that may take months to heal. People who keep pushing themselves past their limit could watch their baseline for exertion drop, and then drop again. “Every time you PEM yourself, you travel a little further down the rabbit hole,” Betsy Keller, an exercise physiologist at Ithaca College, told me.

    Still, the goal of managing PEM has never been to “just lay in a bed all day and don’t do anything,” Lily Chu, the vice president of the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (IACFS/ME), told me. In the 1960s, a group of scientists found that three weeks of bed rest slashed healthy young men’s capacity for exertion by nearly 30 percent. (The participants eventually trained themselves back to baseline.) Long periods of bed rest were once commonly prescribed for recovery from heart attacks, says Prashant Rao, a sports cardiologist at Beth Israel Deaconess Medical Center, in Massachusetts. But now too much rest is actively avoided, because “there’s a real risk of spiraling down, and symptoms worsening,” Rao told me. “I really fear for that, even for people with PEM.”

    There is no rulebook for threading this needle, which has led researchers to approach treatments and rehabilitation for long COVID in different ways. Some clinical trials that involve exercise as an intervention explicitly exclude people with PEM. “We did not feel like the exercise program we designed would be safe for those individuals,” Johanna Sick, a physiologist at the University of Vienna who is helping run one such trial, told me.

    Other researchers hold out hope that activity-based interventions may still help long-haulers, and are keeping patients with PEM in experiments. But some of those decisions have been controversial. The government-sponsored RECOVER trial was heavily criticized last year for its plan to enroll long-haulers in an exercise study. Scientists have since revised the trial’s design to reroute participants with moderate to severe PEM to another intervention, according to Adrian Hernandez, the Duke cardiologist leading the trial. The details are still being finalized, but the plan is to instead look at pacing, a strategy for monitoring activity levels to ensure that people stay below their crash threshold, Janna Friedly, a physiatrist at the University of Washington who’s involved in the trial, told me.

    Certain experimental regimens can be light enough—stretching, recumbent exercises—to be tolerable by many (though not all) people with PEM. Some researchers are trying to monitor participants’ heart rate, and having them perform only activities that keep them in a low-intensity zone. But even when patients’ limitations are taken into account, crashes can be hard to avoid, Tania Janaudis-Ferreira, a physiotherapist at McGill University, in Quebec, told me. She recently wrapped a clinical trial in which, despite tailoring the regimen to each individual, her team still documented several mild to moderate crashes among participants with PEM.

    Read: Long COVID is being erased—again

    Just how worrisome crashes are is another matter of contention. Pavlos Bobos, a musculoskeletal-health researcher at the University of Western Ontario, told me that he’d like to see more evidence of harm before ruling out exercise for long COVID and PEM. Bruno Gualano, a physiologist at the University of São Paulo, told me that even though crashes seem temporarily damaging, he’s not convinced that exercise worsens PEM in the long term. But Putrino, of Mount Sinai, is adamant that crashes set people back; most other experts I spoke with agreed. And several researchers told me that, because PEM seems to upend basic physiology, reduced activity may not be as worrisome for people with the condition as it is for those without.

    For Shoemaker, the calculus is clear. “Coming back from being deconditioned is honestly trivial compared to recovering from PEM,” she told me. She’s willing to wait for evidence-based therapies that can safely improve her PEM. “Whatever we figure out, if I could get healthy,” she told me, “then I can get back in shape.”

    At this point, several patients and researchers told me, most exercise-based trials for long COVID seem to be at best a waste of resources, and at worst a recipe for further harm. PEM is not new, nor are the interventions being tested. Decades of research on ME/CFS have already shown that traditional exercise therapy harms more often than it helps. (Some researchers insisted that more PEM studies are needed in long-haulers—just in case the condition diverges substantially from its manifestation in ME/CFS.) And although a subset of long-haulers could be helped by exercise, experts don’t yet have a great way to safely distinguish them from the rest.

    Even pacing, although often recommended for symptom management, is not generally considered to be a reliable treatment, which is where most long-COVID patient advocates say funds should be focused. Ideally, Putrino and others told me, resources should be diverted to trials investigating drugs that might address PEM’s roots, such as the antiviral Paxlovid, which could clear lingering virus from long-haulers’ tissues. Some researchers are also hopeful about pyridostigmine, a medication that might enhance the delivery of oxygen to tissues, as well as certain supplements that might support mitochondria on the fritz.

    Those interventions are still experimental—and Putrino said that no single one is likely to work for everyone. That only adds to the challenge of studying PEM, which has been shrouded in disbelief for decades. Despite years of research on ME/CFS, Chu, of the IACFS/ME, told me that many people with the condition have encountered medical professionals who suggest that they’re just anxious, even lazy. It doesn’t help that there’s not yet a blood test for PEM; to diagnose it, doctors must ask their patients questions and trust the answers. Just two decades ago, researchers and physicians speculated that PEM stemmed from an irrational fear of activity; some routinely prescribed therapy, antidepressants, and just pushing through, Chu said. One highly publicized 2011 study, since widely criticized as shoddy science, appeared to support those claims—influencing treatment recommendations from top health authorities such as the CDC.

    The CDC and other organizations have since reversed their position on exercise and cognitive behavioral therapy as PEM treatments. Even so, many people with long COVID and ME/CFS are still routinely told to blow past their limits. All of the long-haulers I spoke with have encountered this advice, and learned to ignore it. Fighting those calls to exercise can be exhausting in its own right. As Ed Yong wrote in The Atlantic last year, American society has long stigmatized people who don’t push their way through adversity—even if that adversity is a medically documented condition that cannot be pushed through. Reconceptualizing the role of exercise in daily living is already a challenge; it is made all the more difficult when being productive—even overworked—is prized above all else.

    Read: Fatigue can shatter a person

    Long-haulers know that tension intimately; some have had to battle it within themselves. When Julia Moore Vogel, a researcher at Scripps, developed long COVID in the summer of 2020, she was at first determined to grit her way through. She took up pilates and strength training, workouts she at the time considered gentle. But the results were always the same: horrific migraines that relegated her to bed. She now does physical therapy to keep herself moving in safe and supervised amounts. When Vogel, a former competitive runner, started her program, she was taken aback by how little she was asked to do—sometimes just two reps of chin tucks. “I would always laugh because I would be like, ‘These are not exercises,’” she told me. “I’ve had to change my whole mental model about what exercise is, what exertion is.”

  • What Fatigue Really Means

    What Fatigue Really Means

    Alexis Misko’s health has improved enough that, once a month, she can leave her house for a few hours. First, she needs to build up her energy by lying in a dark room for the better part of two days, doing little more than listening to audiobooks. Then she needs a driver, a quiet destination where she can lie down, and days of rest to recover afterward. The brief outdoor joy “never quite feels like enough,” she told me, but it’s so much more than what she managed in her first year of long COVID, when she couldn’t sit upright for more than an hour or stand for more than 10 minutes. Now, at least, she can watch TV on the same day she takes a shower.

    In her previous life, she pulled all-nighters in graduate school and rough shifts at her hospital as an occupational therapist; she went for long runs and sagged after long flights. None of that compares with what she has endured since getting COVID-19 almost three years ago. The fatigue she now feels is “like a complete depletion of the essence of who you are, of your life force,” she told me in an email.

    Fatigue is among the most common and most disabling of long COVID’s symptoms, and a signature of similar chronic illnesses such as myalgic encephalomyelitis (also known as chronic fatigue syndrome or ME/CFS). But in these diseases, fatigue is so distinct from everyday weariness that most of the people I have talked with were unprepared for how severe, multifaceted, and persistent it can be.

    For a start, this fatigue isn’t really a single symptom; it has many faces. It can weigh the body down: Lisa Geiszler likens it to “wearing a lead exoskeleton on a planet with extremely high gravity, while being riddled with severe arthritis.” It can rev the body up: Many fatigued people feel “wired and tired,” paradoxically in fight-or-flight mode despite being utterly depleted. It can be cognitive: Thoughts become sluggish, incoherent, and sometimes painful—like “there’s steel wool stuck in my frontal lobe,” Gwynn Dujardin, a literary historian with ME, told me.

    Fatigue turns the most mundane of tasks into an “agonizing cost-benefit analysis,” Misko said. If you do laundry, how long will you need to rest to later make a meal? If you drink water, will you be able to reach the toilet? Only a quarter of long-haulers have symptoms that severely limit their daily activities, but even those with “moderate” cases are profoundly limited. Julia Moore Vogel, a program director at Scripps Research, still works, but washing her hair, she told me, leaves her as exhausted as the long-distance runs she used to do.

    And though normal fatigue is temporary and amenable to agency—even after a marathon, you can will yourself into a shower, and you’ll feel better after sleeping—rest often fails to cure the fatigue of long COVID or ME/CFS. “I wake up fatigued,” Letícia Soares, who has long COVID, told me.

    Between long COVID, ME/CFS, and other energy-limiting chronic illnesses, millions of people in the U.S. alone experience debilitating fatigue. But American society tends to equate inactivity with immorality, and productivity with worth. Faced with a condition that simply doesn’t allow people to move—even one whose deficits can be measured and explained—many doctors and loved ones default to disbelief. When Soares tells others about her illness, they usually say, “Oh yeah, I’m tired too.” When she was bedbound for days, people told her, “I need a weekend like that.” Soares’s problems are very real, and although researchers have started to figure out why so many people like her are suffering, they don’t yet know how to stop it.

    Fatigue creates a background hum of disability, but it can be punctuated by worse percussive episodes that strip long-haulers of even the small amounts of energy they normally have.

    Daria Oller is a physiotherapist and athletic trainer, so when she got COVID in March 2020, she naturally tried exercising her way to better health. And she couldn’t understand why, after just short runs, her fatigue, brain fog, chest pain, and other symptoms would flare up dramatically—to the point where she could barely move or speak. These crashes contradicted everything she had learned during her training. Only after talking with physiotherapists with ME/CFS did she realize that this phenomenon has a name: post-exertional malaise.

    Post-exertional malaise, or PEM, is the defining trait of ME/CFS and a common feature of long COVID. It is often portrayed as an extreme form of fatigue, but it is more correctly understood as a physiological state in which all existing symptoms burn more fiercely and new ones ignite. Beyond fatigue, people who get PEM might also feel intense radiant pain, an inflammatory burning feeling, or gastrointestinal and cognitive problems: “You feel poisoned, flu-ish, concussed,” Misko said. And where fatigue usually sets in right after exertion, PEM might strike hours or days later, and with disproportionate ferocity. Even gentle physical or mental effort might lay people out for days, weeks, months. Visiting a doctor can precipitate a crash, and so can filling out applications for disability benefits—or sensing bright lights and loud sounds, regulating body temperature on hot days, or coping with stress. And if in fatigue your batteries feel drained, in PEM they’re missing entirely. It’s the annihilation of possibility: Most people experience the desperation of being unable to move only in nightmares, Dujardin told me. “PEM is like that, but much more painful.”

    Medical professionals generally don’t learn about PEM during their training. Many people doubt its existence because it is so unlike anything that healthy people endure. Mary Dimmock told me that she understood what it meant only when she saw her son, Matthew, who has ME/CFS, crash in front of her eyes. “He just melted,” Dimmock said. But most people never see such damage because PEM hides those in the midst of it from public view. And because it usually occurs after a delay, people who experience PEM might appear well to friends and colleagues who then don’t witness the exorbitant price they later pay.

    That price is both real and measurable. In cardiopulmonary exercise tests, or CPETs, patients use treadmills or exercise bikes while doctors record their oxygen consumption, blood pressure, and heart rate. Betsy Keller, an exercise physiologist at Ithaca College, told me that most people can repeat their performance if retested one day later, even if they have heart disease or are deconditioned by inactivity. People who get PEM cannot. Their results are so different the second time around that when Keller first tested someone with ME/CFS in 2003, “I told my colleagues that our equipment was out of calibration,” she said. But she and others have seen the same pattern in hundreds of ME/CFS and long-COVID patients—“objective findings that can’t be explained by anything psychological,” David Systrom, a pulmonologist at Brigham and Women’s Hospital, told me. “Many patients are told it’s all in their head, but this belies that in spades.” Still, many insurers refuse to pay for a second test, and many patients cannot do two CPETs (or even one) without seriously risking their health. And “20 years later, I still have physicians who refute and ignore the objective data,” Keller said. (Some long-COVID studies have ignored PEM entirely, or bundled it together with fatigue.)

    Oller thinks this dismissal arises because PEM inverts the dogma that exercise is good for you—an adage that, for most other illnesses, is correct. “It’s not easy to change what you’ve been doing your whole career, even when I tell someone that they might be harming their patients,” she said. Indeed, many long-haulers get worse because they don’t get enough rest in their first weeks of illness, or try to exercise through their symptoms on doctors’ orders.

    People with PEM are also frequently misdiagnosed. They’re told that they’re deconditioned from being too sedentary, when their inactivity is the result of frequent crashes, not the cause. They’re told that they’re depressed and unmotivated, when they are usually desperate to move and either physically incapable of doing so or using restraint to avoid crashing. Oller is part of a support group of 1,500 endurance athletes with long COVID who are well used to running, swimming, and biking through pain and tiredness. “Why would we all just stop?” she asked.

    Some patients with energy-limiting illnesses argue that the names of their diseases and symptoms make them easier to discredit. Fatigue invites people to minimize severe depletion as everyday tiredness. Chronic fatigue syndrome collapses a wide-ranging disabling condition into a single symptom that is easy to trivialize. These complaints are valid, but the problem runs deeper than any name.

    Dujardin, the English professor who is (very slowly) writing a cultural history of fatigue, thinks that our concept of it has been impoverished by centuries of reductionism. As the study of medicine slowly fractured into anatomical specialties, it lost an overarching sense of the systems that contribute to human energy, or its absence. The concept of energy was (and still is) central to animistic philosophies, and though once core to the Western world, too, it is now culturally associated with quackery and pseudoscience. “There are vials of ‘energy boosters’ by every cash register in the U.S.,” Dujardin said, but when the NIH convened a conference on the biology of fatigue in 2021, “specialists kept observing that no standard definition exists for fatigue, and everyone was working from different ideas of human energy.” These terms have become so unhelpfully unspecific that our concept of “fatigue” can encompass a wide array of states including PEM and idleness, and can be heavily influenced by social forces—in particular the desire to exploit the energy of others.

    As the historian Emily K. Abel notes in Sick and Tired: An Intimate History of Fatigue, many studies of everyday fatigue at the turn of the 20th century focused on the weariness of manual laborers, and were done to find ways to make those workers more productive. During this period, fatigue was recast from a physiological limit that employers must work around into a psychological failure that individuals must work against. “Present-day society stigmatizes those who don’t Push through; keep at it; show grit,” Dujardin said, and for the sin of subverting those norms, long-haulers “are not just disbelieved but treated openly with contempt.” Fatigue is “profoundly anti-capitalistic,” Jaime Seltzer, the director of scientific and medical outreach at the advocacy group MEAction, told me.

    Energy-limiting illnesses also disproportionately affect women, who have long been portrayed as prone to idleness. Dujardin notes that in Western epics, women such as Circe and Dido were perceived harshly for averting questing heroes such as Odysseus and Aeneas with the temptation of rest. Later, the onset of industrialization turned women instead into emblems of homebound idleness while men labored in public. As shirking work became a moral failure, it also remained a feminine one.

    These attitudes were evident in the ways two successive U.S. presidents dealt with COVID. Donald Trump, who always evinced a caricature of masculine strength and chastised rivals for being “low energy,” framed his recovery from the coronavirus as an act of domination. Joe Biden was less bombastic, but he still conspicuously assured the public that he was working through his COVID infection while his administration prioritized policies that got people back to work. Neither man spoke of the possibility of disabling fatigue or the need for rest.

    Medicine, too, absorbs society’s stigmas around fatigue, even in selecting those who get to join its ranks. Its famously grueling training programs exclude (among others) most people with energy-limiting illnesses, while valorizing the ability to function when severely depleted. This, together with the tendency to psychologize women’s pain, helps to explain why so many long-haulers—even those with medical qualifications, like Misko and Oller—are treated so badly by the professionals they see for care. When Dujardin first sought medical help for her ME/CFS symptoms, the same doctor who had treated her well for a decade suddenly became stiff and suspicious, she told me, reduced all of her detailed descriptions to “tiredness,” and left the room without offering diagnosis or treatment. There is so much cultural pressure to never stop that many people can’t accept that their patients or peers might be biologically forced to do so.

    No grand unified theory explains everything about long COVID and ME/CFS, but neither are these diseases total mysteries. In fact, plenty of evidence exists for at least two pathways that explain why people with these conditions could be so limited in energy.

    First, most people with energy-limiting chronic illnesses have problems with their autonomic nervous system, which governs heartbeat, breathing, sleep, hormone release, and other bodily functions that we don’t consciously control. When this system is disrupted—a condition called “dysautonomia”—hormones such as adrenaline might be released at inappropriate moments, leading to the wired-but-tired feeling. People might suddenly feel sleepy, as if they’re shutting down. Blood vessels might not expand in moments of need, depriving active muscles and organs of oxygen and fuel; those organs might include the brain, leading to cognitive dysfunction such as brain fog.

    Second, many people with long COVID and ME/CFS have problems with generating energy. When viruses invade the body, the immune system counterattacks, triggering a state of inflammation. Both infection and inflammation can damage the mitochondria—the bean-shaped batteries that power our cells. Malfunctioning mitochondria produce violent chemicals called “reactive oxygen species” (ROS) that inflict even more cellular damage. Inflammation also triggers a metabolic switch toward fast but inefficient ways of making energy, depleting cells of fuel and riddling them with lactic acid. These changes collectively explain the pervasive, dead-battery flavor of fatigue, as “the body struggles to generate energy,” Bindu Paul, a pharmacologist and neuroscientist at Johns Hopkins, told me. They might also explain the burning, poisoned feelings that patients experience, as their cells fill with lactic acid and ROS.

    These two pathways—autonomic and metabolic—might also account for PEM. Normally, the autonomic nervous system smoothly dials up to an intense fight-and-flight mode and down to a calmer rest-and-digest one. But “in dysautonomia, the dial becomes a switch,” David Putrino, a neuroscientist and rehabilitation specialist at Mount Sinai, told me. “You go from sitting to standing and your body thinks: Oh, are we going hunting? You stop, and your body shuts down.” The exhaustion of these dramatic, unstable flip-flops is made worse by the ongoing metabolic maelstrom. Damaged mitochondria, destructive ROS, inefficient metabolism, and chronic inflammation all compound one another in a vicious cycle that, if it becomes sufficiently intense, could manifest as a PEM crash. “No one is absolutely certain about what causes PEM,” Seltzer told me, but it makes sense that “you have this big metabolic shift and your nervous system can’t get back on an even keel.” And if people push through, deepening the metabolic demands on a body that already can’t meet them, the cycle can spin even faster, “leading to progressive disability,” Putrino said.

    Other factors might also be at play. Compared with healthy people, those with long COVID and ME/CFS have differences in the size, structure, or function of brain regions including the thalamus, which relays motor signals and regulates consciousness, and the basal ganglia, which controls movement and has been implicated in fatigue. Long-haulers also have problems with blood vessels, red blood cells, and clotting, all of which might further staunch their flows of blood, oxygen, and nutrients. “I’ve tested so many of these people over the years, and we see over and over again that when the systems start to fail, they all fail in the same way,” Keller said. Together, these woes explain why long COVID and ME/CFS have such bewilderingly varied symptoms. That diversity fuels disbelief—how could one disease cause all of this?—but it’s exactly what you’d expect if things as fundamental as metabolism go awry.

    Long-haulers might not know the biochemical specifics of their symptoms, but they are uncannily good at capturing those underpinnings through metaphor. People experiencing autonomic blood-flow problems might complain about feeling “drained,” and that’s literally happening: In POTS, a form of dysautonomia, blood pools in the lower body when people stand. People experiencing metabolic problems often use dead-battery analogies, and indeed their cellular batteries—the mitochondria—are being damaged: “It really feels like something is going wrong at the cellular level,” Oller told me. Attentive doctors can find important clues about the basis of their patients’ illness hiding amid descriptions that are often billed as “exaggerated or melodramatic,” Dujardin said.

    Some COVID long-haulers do recover. But several studies have found that, so far, most don’t fully return to their previous baseline, and many who become severely ill stay that way. This pool of persistently sick people is now mired in the same neglect that has long plagued those who suffer from illnesses such as ME/CFS. Research into such conditions are grossly underfunded, so no cures exist. Very few doctors in the U.S. know how to treat these conditions, and many are nearing retirement, so patients struggle to find care. Long-COVID clinics exist but vary in quality: Some know nothing about other energy-limiting illnesses, and still prescribe potentially harmful and officially discouraged treatments such as exercise. Clinicians who better understand these illnesses know that caution is crucial. When Putrino works with long-haulers to recondition their autonomic nervous system, he always starts as gently as possible to avoid triggering PEM. Such work “isn’t easy and isn’t fast,” he said, and it usually means stabilizing people instead of curing them.

    Stability can be life-changing, especially when it involves changes that patients can keep up at home. Over-the-counter supplements such as coenzyme Q10, which is used by mitochondria to generate energy and is depleted in ME/CFS patients, can reduce fatigue. Anti-inflammatory medications such as low-dose naltrexone may have some promise. Sleep hygiene may not cure fatigue, but certainly makes it less debilitating. Dietary changes can help, but the right ones might be counterintuitive: High-fiber foods take more energy to digest, and some long-haulers get PEM episodes after eating meals that seem healthy. And the most important part of this portfolio is “pacing”—a strategy for carefully keeping your activity levels beneath the threshold that causes debilitating crashes.

    Pacing is more challenging than it sounds. Practitioners can’t rely on fixed routines; instead, they must learn to gauge their fluctuating energy levels in real time, while becoming acutely aware of their PEM triggers. Some turn to wearable technology such as heart-rate monitors, and more than 30,000 are testing a patient-designed app called Visible to help spot patterns in their illness. Such data are useful, but the difference between rest and PEM might be just 10 or 20 extra heartbeats a minute—a narrow crevice into which long-haulers must squeeze their life. Doing so can be frustrating, because pacing isn’t a recovery tactic; it’s mostly a way of not getting worse, which makes its value harder to appreciate. Its physical benefits come at mental costs: Walks, workouts, socializing, and “all the things I’d do for mental health before were huge energy sinks,” Vogel told me. And without financial stability or social support, many long-haulers must work, parent, and care for themselves even knowing that they’ll suffer later. “It’s impossible not to overdo it, because life is life,” Vogel said.

    “Our society is not set up for pacing,” Oller added. Long-haulers must resist the enormous cultural pressure to prove their worth by pushing as hard as they can. They must tolerate being chastised for trying to avert a crash, and being disbelieved if they fail. “One of the most insulting things people can say is ‘Fight your illness,’” Misko said. That would be much easier for her. “It takes so much self-control and strength to do less, to be less, to shrink your life down to one or two small things from which you try to extract joy in order to survive.” For her and many others, rest has become both a medical necessity and a radical act of defiance—one that, in itself, is exhausting.

  • Long-Haulers Are Trying to Define Themselves

    Long-Haulers Are Trying to Define Themselves

    Imagine you need to send a letter. The mailbox is only two blocks away, but the task feels insurmountable. Air hunger seizes you whenever you walk, you’re plagued by dizziness and headaches, and anyway, you keep blanking on your zip code for the return address. So you sit in the kitchen, disheartened by the letter you can’t send, the deadlines you’ve missed, the commitments you’ve canceled. Months have passed since you got COVID. Weren’t you supposed to feel better by now?

    Long COVID is a diverse and confusing condition, a new disease with an unclear prognosis, often-fluctuating symptoms, and a definition people still can’t agree on. And in many cases, it is disabling. In a recent survey, 1.6 percent of American adults said post-COVID symptoms limit their daily activities “a lot.” That degree of upheaval aligns with the Americans With Disabilities Act’s definition of disability: “a physical or mental impairment that substantially limits one or more major life activities.”

    But for many people experiencing long COVID who were able-bodied before, describing themselves as “disabled” is proving to be a complicated decision. This country is not kind to disabled people: American culture and institutions tend to operate on the belief that a person’s worth derives from their productivity and physical or cognitive abilities. That ableism was particularly stark in the early months of the pandemic, when some states explicitly de-prioritized certain groups of disabled people for ventilators. Despite the passage of the ADA in 1990, disabled people still confront barriers accessing things such as jobs and health care, and even a meal with friends at a restaurant. Most of our cultural narratives cast disability as either a tribulation to overcome or a tragedy.

    Consequently, incorporating disability into your identity can require a lot of reflection. Lizzie Jones, who finished her doctoral research in disability studies last year and now works for an educational consultancy, suffered a 30-foot fall that shattered half of her body a week before her college graduation. She told me that her accident prompted “radical identity shifts” as she transitioned from trying to get the life she’d imagined back on track to envisioning a new one.

    These are the sorts of mindset changes that Ibrahim Rashid struggled with after contracting COVID in November 2020, when he was a graduate student. He dealt with debilitating symptoms for months, but even after applying for disability accommodations to finish his degree, he “was so scared of that word,” he told me. Rashid was afraid of people treating him differently and of losing his internship offer. Most terrifying, calling himself disabled felt like an admission that his long COVID wasn’t going to suddenly resolve.

    Jennifer Senior: What not to ask me about my long COVID

    Aaron Teasdale, an outdoors and travel writer and a mountaineer, has also been wrestling with identity questions since he got COVID in January 2022. For months, he spent most of his time in a remote-controlled bed, gazing out the window at the Montana forests he once skied. Although his fatigue is now slowly improving, he had to take Ritalin to speak with me. He was still figuring out what being disabled meant to him, whether it simply described his current condition or reflected some new, deeper part of himself—a reckoning made more difficult by the unknowability of his prognosis. “Maybe I just need more time before I say I’m a disabled person,“ he said. “When you have your greatest passions completely taken away from you, it does leave you questioning, Well, who am I?”

    Long COVID can wax and wane, leaving people scrambling to adapt. It doesn’t mesh with the stereotype of disability as static, visible, and binary—the wheelchair user cast in opposition to the pedestrian. Nor does the fact that long COVID is often imperceptible in casual interactions, which forces long-haulers to contend with disclosure and the possibility of passing as able-bodied. One such long-hauler is Julia Moore Vogel, a program director at Scripps Research, who initially hesitated at the idea of getting a disabled-parking permit. “My first thought was, I’m not disabled, because I can walk,” she told me. But if she did walk, she’d be drained for days. Taking her daughter to the zoo or the beach was out of the question.

    Once she got over her apprehension, identifying as disabled ended up feeling empowering. Getting that permit was “one of the best things I’ve done for myself,” Vogel told me. She could drive her kid to the playground, park nearby, and then sit and watch her play. After plenty of therapy and conversations with other disabled people, Rashid, too, came to embrace disability as part of his identity, so much so that he now speaks and writes about chronic illness.

    Read: The future of long COVID

    Usually, the community around a disease—including advocacy among those it disables—arises after scientists name it. Long COVID upended that order, because the term first spread through hashtags and support groups in 2020. Instead of doctors informing patients of whether their symptoms fit a certain illness, patients were telling doctors what symptoms their illness entailed. And there were a lot of symptoms: everything from life-altering neurocognitive problems and dizziness to a mild, persistent cough.

    As long-COVID networks blossomed online, members began seeking support from wider disability-rights communities, and contributing fresh energy and resources to those groups. People who’d fought similar battles for decades sometimes bristled at the greater political capital afforded to long-haulers, whose advocacy didn’t universally extend to other disabled people; for the most part, though, long-haulers were welcomed.

    Tapping into conversations among disabled people “has shown me that I’m simply not alone,” Eris Eady, a writer and an artist who works for Planned Parenthood, told me. Eady, who is queer and Black, found that long COVID interplayed with struggles they already faced on account of their identity. So they sought advice from disabled Black women about interdependence, mutual aid, and accessibility, as well as about being dismissed by doctors, an experience more prevalent among women and people of color.

    Disabled communities have years of experience supporting people through identity changes. The writer and disability-justice organizer Leah Lakshmi Piepzna-Samarasinha told me that when she was newly disabled, she was dogged with heavy questions: Am I going to be able to make a living? Am I datable? Her isolation and fear dissipated only when she met other young disabled people, who taught her how to be creative in “hacking the world.”

    For long-haulers navigating these transitions for the first time, the process can be rocky. Rachel Robles, a contributor to The Long COVID Survival Guide, told me she spent her early months with long COVID “waking up every day and thinking, Okay, is this the day it’s left my body?” Conceiving of herself as disabled didn’t take away her long COVID. She didn’t stop seeing doctors and trying treatments. But thinking about accessibility did inspire her to return to gymnastics, which she’d quit decades earlier because of a heart condition. If she couldn’t lift her hands over her head sometimes, and if a dive roll would never be in her future, then so be it: Gymnastics could be about enjoying what her body could do, not yearning for what it couldn’t. Before she identified as disabled, returning to gymnastics “was something I would have never, ever imagined,” Robles said. And she never would have done it had she remained focused only on when she might recover.

    Read: Long COVID is being erased—again

    Hoping for improvement is a natural response to illness, especially one with a trajectory as uncertain as long COVID’s. But focusing exclusively on relinquished past identities or unrealized future ones can dampen our curiosity about the present. A better way to think about it is “What are the things you can do with the body that you have, and what are the things you might not know you can do yet?” Piepzna-Samarasinha said. “Who am I right now?”

  • Long COVID Is Being Erased—Again

    Long COVID Is Being Erased—Again

    Updated at 6:29 p.m. ET on April 21, 2023

    Charlie McCone has been struggling with the symptoms of long COVID since he was first infected, in March 2020. Most of the time, he is stuck on his couch or in his bed, unable to stand for more than 10 minutes without fatigue, shortness of breath, and other symptoms flaring up. But when I spoke with him on the phone, he seemed cogent and lively. “I can appear completely fine for two hours a day,” he said. No one sees him in the other 22.  He can leave the house to go to medical appointments, but normally struggles to walk around the block. He can work at his computer for an hour a day. “It’s hell, but I have no choice,” he said. Like many long-haulers, McCone is duct-taping himself together to live a life—and few see the tape.

    McCone knows 12 people in his pre-pandemic circles who now also have long COVID, most of whom confided in him only because “I’ve posted about this for three years, multiple times a week, on Instagram, and they’ve seen me as a resource,” he said. Some are unwilling to go public, because they fear the stigma and disbelief that have dogged long COVID. “People see very little benefit in talking about this condition publicly,” he told me. “They’ll try to hide it for as long as possible.”

    I’ve heard similar sentiments from many of the dozens of long-haulers I’ve talked with, and the hundreds more I’ve heard from, since first reporting on long COVID in June 2020. Almost every aspect of long COVID serves to mask its reality from public view. Its bewilderingly diverse symptoms are hard to see and measure. At its worst, it can leave people bed- or housebound, disconnected from the world. And although milder cases allow patients to appear normal on some days, they extract their price later, in private. For these reasons, many people don’t realize just how sick millions of Americans are—and the invisibility created by long COVID’s symptoms is being quickly compounded by our attitude toward them.

    Most Americans simply aren’t thinking about COVID with the same acuity they once did; the White House long ago zeroed in on hospitalizations and deaths as the measures to worry most about. And what was once outright denial of long COVID’s existence has morphed into something subtler: a creeping conviction, seeded by academics and journalists and now common on social media, that long COVID is less common and severe than it has been portrayed—a tragedy for a small group of very sick people, but not a cause for societal concern. This line of thinking points to the absence of disability claims, the inconsistency of biochemical signatures, and the relatively small proportion of severe cases as evidence that long COVID has been overblown. “There’s a shift from ‘Is it real?’ to ‘It is real, but …,’” Lekshmi Santhosh, the medical director of a long-COVID clinic at UC San Francisco, told me.

    Yet long COVID is a substantial and ongoing crisis—one that affects millions of people. However inconvenient that fact might be to the current “mission accomplished” rhetoric, the accumulated evidence, alongside the experience of long haulers, makes it clear that the coronavirus is still exacting a heavy societal toll.

    As it stands, 11 percent of adults who’ve had COVID are currently experiencing symptoms that have lasted for at least three months, according to data collected by the Census Bureau and the CDC through the national Household Pulse Survey. That equates to more than 15 million long-haulers, or 6 percent of the U.S. adult population. And yet, “I run into people daily who say, ‘I don’t know anyone with long COVID,’” says Priya Duggal, an epidemiologist and a co-lead of the Johns Hopkins COVID Long Study. The implication is that the large survey numbers cannot be correct; given how many people have had COVID, we’d surely know if one in 10 of our contacts was persistently unwell.

    But many factors make that unlikely. Information about COVID’s acute symptoms was plastered across our public spaces, but there was never an equivalent emphasis that even mild infections can lead to lasting and mercurial symptoms; as such, some people who have long COVID don’t even know what they have. This may be especially true for the low-income, rural, and minority groups that have borne the greatest risks of infection. Lisa McCorkell, a long-hauler who is part of the Patient-Led Research Collaborative, recently attended a virtual meeting of Bay Area community leaders, and “when I described what it is, some people in the chat said, ‘I just realized I might have it.’”

    Admitting that you could have a life-altering and long-lasting condition, even to yourself, involves a seismic shift in identity, which some people are understandably loath to make. “Everyone I know got Omicron and got over it, so I really didn’t want to concede that I didn’t survive this successfully,” Jennifer Senior, a friend and fellow staff writer at The Atlantic, who has written about her experience with long COVID, told me. Duggal mentioned an acquaintance who, after a COVID reinfection, can no longer walk the quarter mile to pick her kids up from school, or cook them dinner. But she has turned down Duggal’s offer of an appointment; instead, she is moving across the country for a fresh start. “That is common: I won’t call it ‘long COVID’; I’ll just change everything in my life,” Duggal told me. People who accept the condition privately may still be silent about it publicly. “Disability is often a secret we keep,” Laura Mauldin, a sociologist who studies disability, told me. One in four Americans has a disability; one in 10 has diabetes; two in five have at least two chronic diseases. In a society where health issues are treated with intense privacy, these prevalence statistics, like the one-in-10 figure for long COVID, might also intuitively feel like overestimates.

    Some long-haulers are scared to disclose their condition. They might feel ashamed for still being sick, or wary about hearing from yet another loved one or medical professional that there’s nothing wrong with them. Many long-haulers worry that they’ll be perceived as weak or needy, that their friends will stop seeing them, or that employers will treat them unfairly. Such fears are well founded: A British survey of almost 1,000 long-haulers found that 63 percent experienced overt discrimination because of their illness at least “sometimes,” and 34 percent sometimes regretted telling people that they have long COVID. “So many people in my life have reached out and said, ‘I’m experiencing this,’ but they’re not telling the rest of our friends,” McCorkell said.

    Imagine that you interact with 50 people on a regular basis, all of whom got COVID. If 10 percent are long-haulers, that’s five people who are persistently sick. Some might not know what long COVID is or might be unwilling to confront it. The others might have every reason to hide their story. “Numbers like 10 percent are not going to naturally present themselves in front of you,” McCone told me. Instead, “you’ll hear from 45 people that they are completely fine.”

    The same factors that stop people from being public about their condition—ignorance, denial, or concerns about stigma—also make them less likely to file for disability benefits. And that process is, to put it mildly, not easy. Applicants need thorough medical documentation; many long-haulers struggle to find doctors who believe their symptoms are real. Even with the right documents, applicants must hack their way through bureaucratic overgrowth, likely while fighting fatigue or brain fog. For these reasons, attempting to measure long COVID through disability claims is a profoundly flawed exercise. Even if people manage to apply, they face an average wait time of seven months and a two-in-three denial rate. McCone took six weeks to put an application together, and, despite having a lawyer and extensive medical documentation, was denied after one day. McCorkell knows many first-wavers—people who’ve had long COVID since March 2020—“who are just getting their approvals now.”

    An alternative source of data comes from the Census Bureau’s Current Population Survey, which simply asks working-age Americans if they have any of six forms of disability. Using that data, Richard Deitz, an economics-research adviser at the Federal Reserve Bank of New York, calculated that about 1.7 million more people now say they do than in mid-2020, reversing a years-long decline. These numbers are lower than expected if one in 10 people who gets COVID really does become a long-hauler, but the survey doesn’t directly capture many of the condition’s most common symptoms, such as fatigue, neurological problems beyond brain fog, and post-exertional malaise, where a patient’s symptoms get dramatically worse after physical or mental exertion. About 900,000 of the newly disabled people are also still working. David Putrino, who leads a long-COVID rehabilitation clinic at Mount Sinai, told me that many of his patients are refused the accommodations required under the Americans With Disabilities Act. Their employers won’t allow them to work remotely or reduce their hours, because, he said, “you look at them and don’t see an obvious disability.”

    Long COVID can also seem bafflingly invisible when people look at it with the wrong tools. For example, a 2022 study by National Institutes of Health researchers compared 104 long-haulers with 85 short-term COVID patients and 120 healthy people and found no differences in measures of heart or lung capacities, cognitive tests, or levels of common biomarkers—bloodstream chemicals that might indicate health problems. This study has been repeatedly used as evidence that long COVID might be fictitious or psychosomatic, but in an accompanying editorial, Aluko Hope, the medical director of Oregon Health and Science University’s long-COVID program, noted that the study exactly mirrors what long-haulers commonly experience: They undergo extensive testing that turns up little and are told, “Everything is normal and nothing is wrong.”

    The better explanation, Putrino told me, is that “cookie-cutter testing” doesn’t work—a problem that long COVID shares with other neglected complex illnesses, such as myalgic encephalomyelitis/chronic-fatigue syndrome and dysautonomia. For example, the NIH study didn’t consider post-exertional malaise, a cardinal symptom of both ME/CFS and long COVID; measuring it requires performing cardiopulmonary tests on two successive days. Most long-haulers also show spiking heart rates when asked to simply stand against a wall for 10 minutes—a sign of problems with their autonomic nervous system. “These things are there if you know where to look,” Putrino told me. “You need to listen to your patients, hear where the virus is affecting them, and test accordingly.”

    Contrary to popular belief, researchers have learned a huge amount about the biochemical basis of long COVID, and have identified several potential biomarkers for the disease. But because long COVID is likely a cluster of overlapping conditions, there might never be a singular blood test that “will tell you if you have long COVID 100 percent of the time,” Putrino said. The best way to grasp the scale of the condition, then, is still to ask people about their symptoms.

    Large attempts to do this have been relatively consistent in their findings: The U.S. Household Pulse Survey estimates that one in 10 people who’ve had COVID currently have long COVID; a large Dutch study put that figure at one in eight. The former study also estimated that 6 percent of American adults are long-haulers; a similar British survey by the Office for National Statistics estimated that 3 percent of the general population is. These cases vary widely in severity, and about one in five long-haulers is barely affected by their symptoms—but the remaining majority very much is. Another one in four long-haulers (or 4 million Americans) has symptoms that severely limit their daily activities. The others might, at best, wake every day feeling as if they haven’t had any rest, or feel trapped in an endless hangover. They might work or socialize when their tidal symptoms ebb, but only by making big compromises: “If I work a full day, I can’t also then make dinner or parent without significant suffering,” JD Davids, who has both long COVID and ME/CFS, told me.

    Some people do recover. A widely cited Israeli study of 1.9 million people used electronic medical records to show that most lingering COVID symptoms “are resolved within a year from diagnosis,” but such data fail to capture the many long-haulers who give up on the medical system precisely because they aren’t getting better or are done with being disbelieved. Other studies that track groups of long-haulers over time have found less rosy results. A French one found that 85 percent of people who had symptoms two months after their infection were still symptomatic after a year. A Scottish team found that 42 percent of its patients had only partially recovered at 18 months, and 6 percent had not recovered at all. The United Kingdom’s national survey shows that 69 percent of people with long COVID have been dealing with symptoms for at least a year, and 41 percent for at least two.

    The most recent data from the U.S. and the U.K. show that the total number of long-haulers has decreased over the past six months, which certainly suggests that people recover in appreciable numbers. But there’s a catch: In the U.K., the number of people who have been sick for more than a year, or who are severely limited by their illness, has gone up. A persistent pool of people is still being pummeled by symptoms—and new long-haulers are still joining the pool. This influx should be slower than ever, because Omicron variants seem to carry a lower risk of triggering long COVID, while vaccines and the drug Paxlovid can lower that risk even further. But though the odds against getting long COVID are now better, more people are taking a gamble, because preventive precautions have been all but abandoned.

    Even if prevalence estimates were a tenth as big, that would still mean more than 1 million Americans are dealing with a chronic illness that they didn’t have three years ago. “When long COVID first came on the scene, everyone told us that once we have the prevalence numbers, we can do something about it,” McCorkell told me. “We got those numbers. Now people say, ‘Well, we don’t believe them. Try again.’”

    To a degree, I sympathize with some of the skepticism regarding long COVID, because the condition challenges our typical sense of what counts as solid evidence. Blood tests, electronic medical records, and disability claims all feel like rigorous lines of objective data. Their limitations become obvious only when you consider what the average long-hauler goes through—and those details are often cast aside because they are “anecdotal” and, by implication, unreliable. This attitude is backwards: The patients’ stories are the ground truth against which all other data must be understood. Gaps between the data and the stories don’t immediately invalidate the latter; they just as likely show the holes in the former.

    Laura Mauldin, the disability sociologist, argues that the U.S. is primed to discount those experiences because the country’s values—exceptionalism, strength, self-reliance—have created what she calls the myth of the able-bodied public. “We cannot accept that our bodies are fallible, or that disability is utterly ordinary and expected,” she told me. “We go to great pains to pretend as though that is not the case.” If we believe that a disabling illness like long COVID is rare or mild, “we protect ourselves from having to look at it.” And looking away is that much easier because chronic illnesses like long COVID are more likely to affect women—“who are more likely to have their symptoms attributed to psychological problems,” Mauldin said—and because the American emphasis on work ethic devalues people who can’t work as much or as hard as their peers.

    Other aspects of long COVID make it hard to grasp. Like other similar, neglected chronic illnesses, it defies a simplistic model of infectious disease in which a pathogen causes a predictable set of easily defined symptoms that alleviate when the bug is destroyed. It challenges our belief in our institutions, because truly contending with what long-haulers go through means acknowledging how poorly the health-care system treats chronically ill patients, how inaccessible social support is to them, and how many callous indignities they suffer at the hands of even those closest to them. Long COVID is a mirror on our society, and the image it reflects is deeply unflattering.

    Most of all, long COVID is a huge impediment to the normalization of COVID. It’s an insistent indicator that the pandemic is not actually over; that policies allowing the coronavirus to spread freely still carry a cost; that improvements such as better indoor ventilation are still wanting; that the public emergency may have been lifted but an emergency still exists; and that millions cannot return to pre-pandemic life. “Everyone wants to say goodbye to COVID,” Duggal told me, “and if long COVID keeps existing and people keep talking about it, COVID doesn’t go away.” The people who still live with COVID are being ignored so that everyone else can live with ignoring it.

  • The Future of Long COVID

    The Future of Long COVID

    In the early spring of 2020, the condition we now call long COVID didn’t have a name, much less a large community of patient advocates. For the most part, clinicians dismissed its symptoms, and researchers focused on SARS-CoV-2 infections’ short-term effects. Now, as the pandemic approaches the end of its third winter in the Northern Hemisphere, the chronic toll of the coronavirus is much more familiar. Long COVID has been acknowledged by prominent experts, national leaders, and the World Health Organization; the National Institutes of Health has set up a billion-dollar research program to understand how and in whom its symptoms unfurl. Hundreds of long-COVID clinics now freckle the American landscape, offering services in nearly every state; and recent data hint that well-vetted drugs to treat or prevent long COVID may someday be widespread. Long COVID and the people battling it are commanding more respect, says Hannah Davis, a co-founder of the Patient-Led Research Collaborative, who has had long COVID for nearly three years: Finally, many people “seem willing to understand.”

    But for all the ground that’s been gained, the road ahead is arduous. Long COVID still lacks a universal clinical definition and a standard diagnosis protocol; there’s no consensus on its prevalence, or even what symptoms fall under its purview. Although experts now agree that long COVID does not refer to a single illness, but rather is an umbrella term, like cancer, they disagree on the number of subtypes that fall within it and how, exactly, each might manifest. Some risk factors—among them, a COVID hospitalization, female sex, and certain preexisting medical conditions—have been identified, but researchers are still trying to identify others amid fluctuating population immunity and the endless slog of viral variants. And for people who have long COVID now, or might develop it soon, the interventions are still scant. To this day, “when someone asks me, ‘How can I not get long COVID?’ I can still only say, ‘Don’t get COVID,’” says David Putrino, a neuroscientist and physical therapist who leads a long-COVID rehabilitation clinic at Mount Sinai’s Icahn School of Medicine.

    As the world turns its gaze away from the coronavirus pandemic, with country after country declaring the virus “endemic” and allowing crisis-caliber interventions to lapse, long-COVID researchers, patients, and activists worry that even past progress could be undone. The momentum of the past three years now feels bittersweet, they told me, in that it represents what the community might lose. Experts can’t yet say whether the number of long-haulers will continue to increase, or offer a definitive prognosis for those who have been battling the condition for months or years. All that’s clear right now is that, despite America’s current stance on the coronavirus, long COVID is far from being beaten.

    Despite an influx of resources into long-COVID research in recent months, data on the condition’s current reach remain a mess—and scientists still can’t fully quantify its risks.

    Recent evidence from two long-term surveys have hinted that the pool of long-haulers might be shrinking, even as new infection rates remain sky-high: Earlier this month, the United Kingdom’s Office for National Statistics released data showing that 2 million people self-reported lingering symptoms at the very start of 2023, down from 2.3 million in August 2022. The U.S. CDC’s Household Pulse Survey, another study based on self-reporting, also recorded a small drop in long-COVID prevalence in the same time frame, from about 7.5 percent of all American adults to roughly 6. Against the massive number of infections that have continued to slam both countries in the pandemic’s third year and beyond, these surveys might seem to imply that long-haulers are leaving the pool faster than newcomers are arriving.

    Experts cautioned, however, that there are plenty of reasons to treat these patterns carefully—and to not assume that the trends will be sustained. It’s certainly better that these data aren’t showing a sustained, dramatic uptick in long-COVID cases. But that doesn’t mean the situation is improving. Throughout the pandemic, the size of the long-COVID pool has contracted or expanded for only two reasons: a change in the rate at which people enter, or at which they exit. Both figures are likely to be in constant flux, as surges of infections come and go, masking habits change, and vaccine and antiviral uptake fluctuates. Davis pointed out that the slight downward tick in both studies captured just a half-year stretch, so the downward slope could be one small portion of an undulating wave. A few hours spent at the beach while the tide is going out wouldn’t be enough to prove that the ocean is drying up.

    Read: We’re bungling the COVID wind-down

    Recent counts of new long-COVID cases might also be undercounts, as testing slows and people encounter more challenges getting diagnosed. That said, it’s still possible that, on a case-by-case basis, the likelihood of any individual developing long COVID after a SARS-CoV-2 infection may have fallen since the pandemic’s start, says Deepti Gurdasani, a clinical epidemiologist at Queen Mary University of London and the University of New South Wales. Population immunity—especially acquired via vaccination—has, over the past three years, better steeled people’s bodies against the virus, and strong evidence supports the notion that vaccines can moderately reduce the risk of developing long COVID. Treatments and behavioral interventions that have become more commonplace may have chipped away at incidence as well. Antivirals can now help to corral the virus early in infection; ventilation, distancing, and masks—when they’re used—can trim the amount of virus that infiltrates the body. And if overall exposure to the virus can influence the likelihood of developing long COVID, that could help explain why so many debilitating cases arose at the very start of the pandemic, when interventions were few and far between, says Steven Deeks, a physician researcher at UC San Francisco.

    There’s not much comfort to derive from those individual-level stats, though, when considering what’s happening on broader scales. Even if immunity makes the average infected person less likely to fall into the long-COVID pool, so many people have been catching the virus that the inbound rate still feels like a flood. “The level of infection in many countries has gone up substantially since 2021,” Gurdasani told me. The majority of long-COVID cases arise after mild infections, the sort for which our immune defenses fade most rapidly. Now that masking and physical distancing have fallen by the wayside, people may be getting exposed to higher viral doses than they were a year or two ago. In absolute terms, then, the number of people entering the long-COVID pool may not really be decreasing. Even if the pool were getting slightly smaller, its size would still be staggering, an ocean of patients with titanic needs. “Anecdotally, we still have an enormous waitlist to get into our clinic,” Putrino told me.

    Deeks told me that he’s seen another possible reason for optimism: People with newer cases of long COVID might be experiencing less debilitating or faster-improving disease, based on what he’s seen. “The worst cases we’ve seen come from the first wave in 2020,” he said. But Putrino isn’t so sure. “If you put an Omicron long-COVID patient in front of me, versus one from the first wave, I wouldn’t be able to tell you who was who,” he said. The two cases would also be difficult to compare, because they’re separated by so much time. Long COVID’s symptoms can wax, wane, and qualitatively change; a couple of years into the future, some long-haulers who’ve just developed the condition may be in a spot that’s similar to where many veterans with the condition are now.

    Read: The flu-ification of COVID policy is almost complete

    Experts’ understanding of how often people depart the long-COVID pool is also meager. Some long-haulers have undoubtedly seen improvement—but without clear lines distinguishing short COVID from medium and long COVID, entry and exit into these various groups is easy to over- or underestimate. What few data exist on the likelihood of recovery or remission is inconsistent, and not always rosy: Investigators of RECOVER, a large national study of long COVID, have calculated that about two-thirds of the long-haulers in their cohort do not return to baseline health. Putrino, who has worked with hundreds of long-haulers since the pandemic began, estimates that although most of his patients experience at least some benefit from a few months of rehabilitation, only about one-fifth to one-quarter of them eventually reach the point of feeling about as well as they did before catching the virus, while the majority hit a middling plateau. A small minority of the people he has treated, he told me, never seem to improve at all.

    Letícia Soares, a long-hauler in Brazil who caught the virus near the start of the pandemic, falls into that final category. Once a disease ecologist who studied parasite transmission in birds, she is now mostly housebound, working when she is able as a researcher for the Patient-Led Research Collaborative. Her days revolve around medications and behavioral modifications she uses for her fatigue, sleeplessness, and chronic pain. Soares no longer has the capacity to cook or frequently venture outside. And she has resigned herself to this status quo until the treatment landscape changes drastically. It is not the life she pictured for herself, Soares told me. “Sometimes I think the person I used to be died in April of 2020.”

    Even long-haulers who have noticed an improvement in their symptoms are wary of overconfidence. Some absolutely do experience what could be called recovery—but for others, the term has gotten loaded, almost a jinx. “If the question is, ‘Are you doing the things you were doing in 2019?’ the answer is largely no,” says JD Davids, a chronic-illness advocate based in New York. For some, he told me, “getting better” has been more defined by a resetting of expectations than a return to good health. Relapses are also not uncommon, especially after repeat encounters with the virus. Lisa McCorkell, a long-hauler and a co-founder of the Patient-Led Research Collaborative, has felt her symptoms partly abate since she first fell ill in the spring of 2020. But, she told me, she suspects that her condition is more likely to deteriorate than further improve—partly because of “how easy it is to get reinfected now.”

    Last week, in his State of the Union address, President Joe Biden told the American public that “we have broken COVID’s grip on us.” Highlighting the declines in the rates of COVID deaths, the millions of lives saved, and the importance of remembering the more than 1 million lost, Biden reminded the nation of what was to come: “Soon we’ll end the public-health emergency.”

    When the U.S.’s state of emergency was declared nearly three years ago, as hospitals were overrun and morgues overflowed, the focus was on severe, short-term disease. Perhaps in that sense, the emergency is close to being over, Deeks told me. But long COVID, though slower to command attention, has since become its own emergency, never formally declared; for the millions of Americans who have been affected by the condition, their relationship with the virus does not yet seem to be in a better place.

    Read: Trying to stop long COVID before it even starts

    Even with many more health-care providers clued into long COVID’s ills, the waiting lists for rehabilitation and treatment remain untenable, Hannah Davis told me. “I consider myself someone who gets exceptional care compared to other people,” she said. “And still, I hear from my doctor every nine or 10 months.” Calling a wrap on COVID’s “emergency” phase could worsen that already skewed supply-demand ratio. Changes to the nation’s funding tactics could strip resources—among them, access to telehealth; Medicaid coverage; and affordable antivirals, tests, and vaccines—from vulnerable populations, including people of color, that aren’t getting their needs met even as things stand, McCorkell told me. And as clinicians internalize the message that the coronavirus has largely been addressed, attention to its chronic impacts may dwindle. At least one of the country’s long-COVID clinics has, in recent months, announced plans to close, and Davis worries that more could follow soon.

    Scientists researching long COVID are also expecting new challenges. Reduced access to testing will complicate efforts to figure out how many people are developing the condition, and who’s most at risk. Should researchers turn their scientific focus away from studying causes and cures for long COVID when the emergency declaration lifts, Davids and others worry that there will be ripple effects on the scientific community’s interest in other, neglected chronic illnesses, such as ME/CFS (myalgic encephalomyelitis or chronic fatigue syndrome), a diagnosis that many long-haulers have also received.

    The end of the U.S.’s official crisis mode on COVID could stymie research in other ways as well. At Johns Hopkins University, the infectious-disease epidemiologists Priya Duggal, Shruti Mehta, and Bryan Lau have been running a large study to better understand the conditions and circumstances that lead to long COVID, and how symptoms evolve over time. In the past two years, they have gathered online survey data from thousands of people who both have and haven’t been infected, and who have and haven’t seen their symptoms rapidly resolve. But as of late, they’ve been struggling to recruit enough people who caught the virus and didn’t feel their symptoms linger. “I think that the people who are suffering from long COVID will always do their best to participate,” Duggal told me. That may not be the case for individuals whose experiences with the virus were brief. A lot of them “are completely over it,” Duggal said. “Their life has moved on.”

    Kate Porter, a Massachusetts-based marketing director, told me that she worries about her family’s future, should long COVID fade from the national discourse. She and her teenage daughter both caught the virus in the spring of 2020, and went on to develop chronic symptoms; their experience with the disease isn’t yet over. “Just because the emergency declaration is expiring, that doesn’t mean that suddenly people are magically going to get better and this issue is going to go away,” Porter told me. After months of relative improvement, her daughter is now fighting prolonged bouts of fatigue that are affecting her school life—and Porter isn’t sure how receptive people will be to her explanations, should their illnesses persist for years to come. “Two years from now, how am I going to explain, ‘Well, this is from COVID, five years ago’?” she said.

    A condition that was once mired in skepticism, scorn, and gaslighting, long COVID now has recognition—but empathy for long-haulers could yet experience a backslide. Nisreen Alwan, a public-health researcher at the University of Southampton, in the U.K., and her colleagues have found that many long-haulers still worry about disclosing their condition, fearing that it could jeopardize their employment, social interactions, and more. Long COVID could soon be slated to become just one of many neglected chronic diseases, poorly understood and rarely discussed.

    Davis doesn’t think that marginalization is inevitable. Her reasoning is grim: Other chronic illnesses have been easier to push to the sidelines, she said, on account of their smaller clinical footprint, but the pool of long-haulers is enormous—comprising millions of people in the U.S. alone. “I think it’s going to be impossible to ignore,” she told me. One way or another, the world will have no choice but to look.

    Long COVID Experts: ‘So Incredibly Clear What’s at Stake’

    It’s estimated that more than a third of people who have had COVID-19 experience neurological complications such as brain fog that persist or develop 3 months after infection. And two thirds of so-called long haulers still have neurological symptoms after 6 months.

  • One of Long COVID’s Worst Symptoms Is Also Its Most Misunderstood

    One of Long COVID’s Worst Symptoms Is Also Its Most Misunderstood

    On March 25, 2020, Hannah Davis was texting with two friends when she realized that she couldn’t understand one of their messages. In hindsight, that was the first sign that she had COVID-19. It was also her first experience with the phenomenon known as “brain fog,” and the moment when her old life contracted into her current one. She once worked in artificial intelligence and analyzed complex systems without hesitation, but now “runs into a mental wall” when faced with tasks as simple as filling out forms. Her memory, once vivid, feels frayed and fleeting. Former mundanities—buying food, making meals, cleaning up—can be agonizingly difficult. Her inner world—what she calls “the extras of thinking, like daydreaming, making plans, imagining”—is gone. The fog “is so encompassing,” she told me, “it affects every area of my life.” For more than 900 days, while other long-COVID symptoms have waxed and waned, her brain fog has never really lifted.

    Of long COVID’s many possible symptoms, brain fog “is by far one of the most disabling and destructive,” Emma Ladds, a primary-care specialist from the University of Oxford, told me. It’s also among the most misunderstood. It wasn’t even included in the list of possible COVID symptoms when the coronavirus pandemic first began. But 20 to 30 percent of patients report brain fog three months after their initial infection, as do 65 to 85 percent of the long-haulers who stay sick for much longer. It can afflict people who were never ill enough to need a ventilator—or any hospital care. And it can affect young people in the prime of their mental lives.

    Long-haulers with brain fog say that it’s like none of the things that people—including many medical professionals—jeeringly compare it to. It is more profound than the clouded thinking that accompanies hangovers, stress, or fatigue. For Davis, it has been distinct from and worse than her experience with ADHD. It is not psychosomatic, and involves real changes to the structure and chemistry of the brain. It is not a mood disorder: “If anyone is saying that this is due to depression and anxiety, they have no basis for that, and data suggest it might be the other direction,” Joanna Hellmuth, a neurologist at UC San Francisco, told me.

    And despite its nebulous name, brain fog is not an umbrella term for every possible mental problem. At its core, Hellmuth said, it is almost always a disorder of “executive function”—the set of mental abilities that includes focusing attention, holding information in mind, and blocking out distractions. These skills are so foundational that when they crumble, much of a person’s cognitive edifice collapses. Anything involving concentration, multitasking, and planning—that is, almost everything important—becomes absurdly arduous. “It raises what are unconscious processes for healthy people to the level of conscious decision making,” Fiona Robertson, a writer based in Aberdeen, Scotland, told me.

    For example, Robertson’s brain often loses focus mid-sentence, leading to what she jokingly calls “so-yeah syndrome”: “I forget what I’m saying, tail off, and go, ‘So, yeah …’” she said. Brain fog stopped Kristen Tjaden from driving, because she’d forget her destination en route. For more than a year, she couldn’t read, either, because making sense of a series of words had become too difficult. Angela Meriquez Vázquez told me it once took her two hours to schedule a meeting over email: She’d check her calendar, but the information would slip in the second it took to bring up her inbox. At her worst, she couldn’t unload a dishwasher, because identifying an object, remembering where it should go, and putting it there was too complicated.

    Memory suffers, too, but in a different way from degenerative conditions like Alzheimer’s. The memories are there, but with executive function malfunctioning, the brain neither chooses the important things to store nor retrieves that information efficiently. Davis, who is part of the Patient-Led Research Collaborative, can remember facts from scientific papers, but not events. When she thinks of her loved ones, or her old life, they feel distant. “Moments that affected me don’t feel like they’re part of me anymore,” she said. “It feels like I am a void and I’m living in a void.”

    Most people with brain fog are not so severely affected, and gradually improve with time. But even when people recover enough to work, they can struggle with minds that are less nimble than before. “We’re used to driving a sports car, and now we are left with a jalopy,” Vázquez said. In some professions, a jalopy won’t cut it. “I’ve had surgeons who can’t go back to surgery, because they need their executive function,” Monica Verduzco-Gutierrez, a rehabilitation specialist at UT Health San Antonio, told me.

    Robertson, meanwhile, was studying theoretical physics in college when she first got sick, and her fog occluded a career path that was once brightly lit. “I used to sparkle, like I could pull these things together and start to see how the universe works,” she told me. “I’ve never been able to access that sensation again, and I miss it, every day, like an ache.” That loss of identity was as disruptive as the physical aspects of the disease, which “I always thought I could deal with … if I could just think properly,” Robertson said. “This is the thing that’s destabilized me most.”

    Robertson predicted that the pandemic would trigger a wave of cognitive impairment in March 2020. Her brain fog began two decades earlier, likely with a different viral illness, but she developed the same executive-function impairments that long-haulers experience, which then worsened when she got COVID last year. That specific constellation of problems also befalls many people living with HIV, epileptics after seizures, cancer patients experiencing so-called chemo brain, and people with several complex chronic illnesses such as fibromyalgia. It’s part of the diagnostic criteria for myalgic encephalomyelitis, also known as chronic fatigue syndrome, or ME/CFS—a condition that Davis and many other long-haulers now have. Brain fog existed well before COVID, affecting many people whose conditions were stigmatized, dismissed, or neglected. “For all of those years, people just treated it like it’s not worth researching,” Robertson told me. “So many of us were told, Oh, it’s just a bit of a depression.”

    Several clinicians I spoke with argued that the term brain fog makes the condition sound like a temporary inconvenience and deprives patients of the legitimacy that more medicalized language like cognitive impairment would bestow. But Aparna Nair, a historian of disability at the University of Oklahoma, noted that disability communities have used the term for decades, and there are many other reasons behind brain fog’s dismissal beyond terminology. (A surfeit of syllables didn’t stop fibromyalgia and myalgic encephalomyelitis from being trivialized.)

    For example, Hellmuth noted that in her field of cognitive neurology, “virtually all the infrastructure and teaching” centers on degenerative diseases like Alzheimer’s, in which rogue proteins afflict elderly brains. Few researchers know that viruses can cause cognitive disorders in younger people, so few study their effects. “As a result, no one learns about it in medical school,” Hellmuth said. And because “there’s not a lot of humility in medicine, people end up blaming patients instead of looking for answers,” she said.

    People with brain fog also excel at hiding it: None of the long-haulers I’ve interviewed sounded cognitively impaired. But at times when her speech is obviously sluggish, “nobody except my husband and mother see me,” Robertson said. The stigma that long-haulers experience also motivates them to present as normal in social situations or doctor appointments, which compounds the mistaken sense that they’re less impaired than they claim—and can be debilitatingly draining. “They’ll do what is asked of them when you’re testing them, and your results will say they were normal,” David Putrino, who leads a long-COVID rehabilitation clinic at Mount Sinai, told me. “It’s only if you check in on them two days later that you’ll see you’ve wrecked them for a week.”

    “We also don’t have the right tools for measuring brain fog,” Putrino said. Doctors often use the Montreal Cognitive Assessment, which was designed to uncover extreme mental problems in elderly people with dementia, and “isn’t validated for anyone under age 55,” Hellmuth told me. Even a person with severe brain fog can ace it. More sophisticated tests exist, but they still compare people with the population average rather than their previous baseline. “A high-functioning person with a decline in their abilities who falls within the normal range is told they don’t have a problem,” Hellmuth said.

    This pattern exists for many long-COVID symptoms: Doctors order inappropriate or overly simplistic tests, whose negative results are used to discredit patients’ genuine symptoms. It doesn’t help that brain fog (and long COVID more generally) disproportionately affects women, who have a long history of being labeled as emotional or hysterical by the medical establishment. But every patient with brain fog “tells me the exact same story of executive-function symptoms,” Hellmuth said. “If people were making this up, the clinical narrative wouldn’t be the same.”

    Earlier this year, a team of British researchers rendered the invisible nature of brain fog in the stark black-and-white imagery of MRI scans. Gwenaëlle Douaud at the University of Oxford and her colleagues analyzed data from the UK Biobank study, which had regularly scanned the brains of hundreds of volunteers for years prior to the pandemic. When some of those volunteers caught COVID, the team could compare their after scans to the before ones. They found that even mild infections can slightly shrink the brain and reduce the thickness of its neuron-rich gray matter. At their worst, these changes were comparable to a decade of aging. They were especially pronounced in areas such as the parahippocampal gyrus, which is important for encoding and retrieving memories, and the orbitofrontal cortex, which is important for executive function. They were still apparent in people who hadn’t been hospitalized. And they were accompanied by cognitive problems.

    Although SARS-CoV-2, the coronavirus that causes COVID, can enter and infect the central nervous system, it doesn’t do so efficiently, persistently, or frequently, Michelle Monje, a neuro-oncologist at Stanford, told me. Instead, she thinks that in most cases the virus harms the brain without directly infecting it. She and her colleagues recently showed that when mice experience mild bouts of COVID, inflammatory chemicals can travel from the lungs to the brain, where they disrupt cells called microglia. Normally, microglia act as groundskeepers, supporting neurons by pruning unnecessary connections and cleaning unwanted debris. When inflamed, their efforts become overenthusiastic and destructive. In their presence, the hippocampus—a region crucial for memory—produces fewer fresh neurons, while many existing neurons lose their insulating coats, so electric signals now course along these cells more slowly. These are the same changes that Monje sees in cancer patients with “chemo fog.” And although she and her team did their COVID experiments in mice, they found high levels of the same inflammatory chemicals in long-haulers with brain fog.

    Monje suspects that neuro-inflammation is “probably the most common way” that COVID results in brain fog, but that there are likely many such routes. COVID could possibly trigger autoimmune problems in which the immune system mistakenly attacks the nervous system, or reactivate dormant viruses such as Epstein-Barr virus, which has been linked to conditions including ME/CFS and multiple sclerosis. By damaging blood vessels and filling them with small clots, COVID also throttles the brain’s blood supply, depriving this most energetically demanding of organs of oxygen and fuel. This oxygen shortfall isn’t stark enough to kill neurons or send people to an ICU, but “the brain isn’t getting what it needs to fire on all cylinders,” Putrino told me. (The severe oxygen deprivation that forces some people with COVID into critical care causes different cognitive problems than what most long-haulers experience.)

    None of these explanations is set in stone, but they can collectively make sense of brain fog’s features. A lack of oxygen would affect sophisticated and energy-dependent cognitive tasks first, which explains why executive function and language “are the first ones to go,” Putrino said. Without insulating coats, neurons work more slowly, which explains why many long-haulers feel that their processing speed is shot: “You’re losing the thing that facilitates fast neural connection between brain regions,” Monje said. These problems can be exacerbated or mitigated by factors such as sleep and rest, which explains why many people with brain fog have good days and bad days. And although other respiratory viruses can wreak inflammatory havoc on the brain, SARS-CoV-2 does so more potently than, say, influenza, which explains both why people such as Robertson developed brain fog long before the current pandemic and why the symptom is especially prominent among COVID long-haulers.

    Perhaps the most important implication of this emerging science is that brain fog is “potentially reversible,” Monje said. If the symptom was the work of a persistent brain infection, or the mass death of neurons following severe oxygen starvation, it would be hard to undo. But neuroinflammation isn’t destiny. Cancer researchers, for example, have developed drugs that can calm berserk microglia in mice and restore their cognitive abilities; some are being tested in early clinical trials. “I’m hopeful that we’ll find the same to be true in COVID,” she said.

    Biomedical advances might take years to arrive, but long-haulers need help with brain fog now. Absent cures, most approaches to treatment are about helping people manage their symptoms. Sounder sleep, healthy eating, and other generic lifestyle changes can make the condition more tolerable. Breathing and relaxation techniques can help people through bad flare-ups; speech therapy can help those with problems finding words. Some over-the-counter medications such as antihistamines can ease inflammatory symptoms, while stimulants can boost lagging concentration.

    “Some people spontaneously recover back to baseline,” Hellmuth told me, “but two and a half years on, a lot of patients I see are no better.” And between these extremes lies perhaps the largest group of long-haulers—those whose brain fog has improved but not vanished, and who can “maintain a relatively normal life, but only after making serious accommodations,” Putrino said. Long recovery periods and a slew of lifehacks make regular living possible, but more slowly and at higher cost.

    Kristen Tjaden can read again, albeit for short bursts followed by long rests, but hasn’t returned to work. Angela Meriquez Vázquez can work but can’t multitask or process meetings in real time. Julia Moore Vogel, who helps lead a large biomedical research program, can muster enough executive function for her job, but “almost everything else in my life I’ve cut out to make room for that,” she told me. “I only leave the house or socialize once a week.” And she rarely talks about these problems openly because “in my field, your brain is your currency,” she said. “I know my value in many people’s eyes will be diminished by knowing that I have these cognitive challenges.”

    Patients struggle to make peace with how much they’ve changed and the stigma associated with it, regardless of where they end up. Their desperation to return to normal can be dangerous, especially when combined with cultural norms around pressing on through challenges and post-exertional malaise—severe crashes in which all symptoms worsen after even minor physical or mental exertion. Many long-haulers try to push themselves back to work and instead “push themselves into a crash,” Robertson told me. When she tried to force her way to normalcy, she became mostly housebound for a year, needing full-time care. Even now, if she tries to concentrate in the middle of a bad day, “I end up with a physical reaction of exhaustion and pain, like I’ve run a marathon,” she said.

    Post-exertional malaise is so common among long-haulers that “exercise as a treatment is inappropriate for people with long COVID,” Putrino said. Even brain-training games—which have questionable value but are often mentioned as potential treatments for brain fog—must be very carefully rationed because mental exertion is physical exertion. People with ME/CFS learned this lesson the hard way, and fought hard to get exercise therapy, once commonly prescribed for the condition, to be removed from official guidance in the U.S. and U.K. They’ve also learned the value of pacing—carefully sensing and managing their energy levels to avoid crashes.

    Vogel does this with a wearable that tracks her heart rate, sleep, activity, and stress as a proxy for her energy levels; if they feel low, she forces herself to rest—cognitively as well as physically. Checking social media or responding to emails do not count. In those moments, “you have to accept that you have this medical crisis and the best thing you can do is literally nothing,” she said. When stuck in a fog, sometimes the only option is to stand still.
