  • Long COVID Is Being Erased—Again

    Long COVID Is Being Erased—Again

    [ad_1]

    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.

  • No One Really Knows How Much COVID Is Silently Spreading … Again

    No One Really Knows How Much COVID Is Silently Spreading … Again

    [ad_1]

    In the early days of the pandemic, one of the scariest and most surprising features of SARS-CoV-2 was its stealth. Initially assumed to transmit only from people who were actively sick—as its predecessor SARS-CoV did—the new coronavirus turned out to be a silent spreader, also spewing from the airways of people who were feeling just fine. After months of insisting that only the symptomatic had to mask, test, and isolate, officials scrambled to retool their guidance; singing, talking, laughing, even breathing in tight quarters were abruptly categorized as threats.

    Three years later, the coronavirus is still silently spreading—but the fear of its covertness again seems gone. Enthusiasm for masking and testing has plummeted; isolation recommendations have been pared down, and may soon entirely disappear. “We’re just not communicating about asymptomatic transmission anymore,” says Saskia Popescu, an infectious-disease epidemiologist and infection-prevention expert at George Mason University. “People think, What’s the point? I feel fine.

    Although the concern over asymptomatic spread has dissipated, the threat itself has not. And even as our worries over the virus continue to shrink and be shunted aside, the virus—and the way it moves between us—is continuing to change. Which means that our best ideas for stopping its spread aren’t just getting forgotten; they’re going obsolete.

    When SARS-CoV-2 was new to the world and hardly anyone had immunity, symptomless spread probably accounted for most of the virus’s spread—at least 50 percent or so, says Meagan Fitzpatrick, an infectious-disease transmission modeler at the University of Maryland’s School of Medicine. People wouldn’t start feeling sick until four, five, or six days, on average, after being infected. In the interim, the virus would be xeroxing itself at high speed in their airway, reaching potentially infectious levels a day or two before symptoms started. Silently infected people weren’t sneezing and coughing—symptoms that propel the virus more forcefully outward, increasing transmission efficiency. But at a time when tests were still scarce and slow to deliver results, not knowing they had the virus made them dangerous all the same. Precautionary tests were still scarce, or very slow to deliver results. So symptomless transmission became a norm, as did epic superspreading events.

    Now, though, tests are more abundant, presymptomatic spread is a better-known danger, and repeated rounds of vaccination and infection have left behind layers of immunity. That protection, in particular, has slashed the severity and duration of acute symptoms, lowering the risk that people will end up in hospitals or morgues; it may even be chipping away at long COVID. At the same time, though, the addition of immunity has made the dynamics of symptomless transmission much more complex.

    On an individual basis, at least, silent spread could be happening less often than it did before. One possible reason is that symptoms are now igniting sooner in people’s bodies, just three or so days, on average, after infection—a shift that roughly coincided with the rise of the first Omicron variant and could be a quirk of the virus itself. But Aubree Gordon, an infectious-disease epidemiologist at the University of Michigan, told me that faster-arriving sicknesses are probably being driven in part by speedier immune responses, primed by past exposures. That means that illness might now coincide with or even precede the peak of contagiousness, shortening the average period in which people spread the virus before they feel sick. In that one very specific sense, COVID could now be a touch more flulike. Presymptomatic transmission of the flu does seem to happen on occasion, says Seema Lakdawala, a virologist at Emory University. But in general, “people tend not to hit their highest viral levels until after they develop symptoms,” Gordon told me.

    Coupled with more population-level immunity, this arrangement could be working in our favor. People might be less likely to pass the virus unwittingly to others. And thanks to the defenses we’ve collectively built up, the pathogen itself is also having more trouble exiting infected bodies and infiltrating new ones. That’s almost certainly part of the reason that this winter hasn’t been quite as bad as past ones have, COVID-wise, says Maia Majumder, an infectious-disease modeler at Harvard Medical School and Boston Children’s Hospital.

    That said, a lot of people are still undoubtedly catching the coronavirus from people who aren’t feeling sick. Infection per infection, the risk of superspreading events might now be lower, but at the same time people have gotten chiller about socializing without masks and testing before gathering in groups—a behavioral change that’s bound to counteract at least some of the forward shift in symptoms. Presymptomatic spread might be less likely nowadays, but it’s nowhere near gone. Multiply a small amount of presymptomatic spread by a large number of cases, and that can still seed … another large number of cases.

    There could be some newcomers to the pool of silent spreaders, too—those who are now transmitting the virus without ever developing symptoms at all. With people’s defenses higher than they were even a year and a half ago, infections that might have once been severe are now moderate or mild; ones that might have once been mild are now unnoticeable, says Seyed Moghadas, a computational epidemiologist at York University. At the same time, though, immunity has probably transformed some symptomless-yet-contagious infections into non-transmissible cases, or kept some people from getting infected at all. Milder cases are of course welcome, Fitzpatrick told me, but no one knows exactly what these changes add up to: Depending on the rate and degree of each of those shifts, totally asymptomatic transmission might now be more common, less common, or sort of a wash.

    Better studies on transmission patterns would help cut through the muck; they’re just not really happening anymore. “To get this data, you need to have pretty good testing for surveillance purposes, and that basically has stopped,” says Yonatan Grad, an infectious-disease epidemiologist at Harvard’s School of Public Health.

    Meanwhile, people are just straight-up testing less, and rarely reporting any of the results they get at home. For many months now, even some people who are testing have been seeing strings of negative results days into bona-fide cases of COVID—sometimes a week or more past when their symptoms start. That’s troubling on two counts: First, some legit COVID cases are probably getting missed, and keeping people from accessing test-dependent treatments such as Paxlovid. Second, the disparity muddles the start and end of isolation. Per CDC guidelines, people who don’t test positive until a few days into their illness should still count their first day of symptoms as Day 0 of isolation. But if symptoms might sometimes outpace contagiousness, “I think those positive tests should restart the isolation clock,” Popescu told me, or risk releasing people back into society too soon.

    American testing guidelines, however, haven’t undergone a major overhaul in more than a year—right after Omicron blew across the nation, says Jessica Malaty Rivera, an infectious-disease epidemiologist at Boston Children’s Hospital. And even if the rules were to undergo a revamp, they wouldn’t necessarily guarantee more or better testing, which requires access and will. Testing programs have been winding down for many months; free diagnostics are once again growing scarce.

    Through all of this, scientists and nonscientists alike are still wrestling with how to define silent infection in the first place. What counts as symptomless depends not just on biology, but behavior—and our vigilance. As worries over transmission continue to falter and fade, even mild infections may be mistaken for quiet ones, Grad told me, brushed off as allergies or stress. Biologically, the virus and the disease may not need to become that much more muted to spread with ease: Forgetting about silent spread may grease the wheels all on its own.
