Why Does Everyone Have a Gnarly Cold Right Now?
For the past few weeks, my daily existence has been scored by the melodies of late winter: the drip of melting ice, the soft rustling of freshly sprouted leaves—and, of course, the nonstop racket of sneezes and coughs.
The lobby of my apartment building is alive with the sounds of sniffles and throats being cleared. Every time I walk down the street, I’m treated to the sight of watery eyes and red noses. Even my work Slack is rife with illness emoji, and the telltale pings of miserable colleagues asking each other why they feel like absolute garbage. “It’s not COVID,” they say. “I tested, like, a million times.” Something else, they insist, is making them feel like a stuffed and cooked goose.
That something else might be the once-overlooked common cold. After three years of largely being punted out of the limelight, a glut of airway pathogens—among them, adenovirus, RSV, metapneumovirus, parainfluenza, common-cold coronaviruses, and rhinoviruses galore—are awfully common again. And they’re really laying some people out. The good news is that there’s no evidence that colds are actually, objectively worse now than they were before the pandemic started. The less-good news is that after years of respite from a bunch of viral nuisances, a lot of us have forgotten that colds can be a real drag.
Once upon a time—before 2020, to be precise—most of us were very, very used to colds. Every year, adults, on average, catch two to three of the more than 200 viral strains that are known to cause the illnesses; young kids may contract half a dozen or more as they toddle in and out of the germ incubators that we call “day cares” and “schools.” The sicknesses are especially common during the winter months, when many viruses thrive amid cooler temps, and people tend to flock indoors to exchange gifts and breath. When the pandemic began, masks and distancing drove several of those microbes into hiding—but as mitigations have eased in the time since, they’ve begun their slow creep back.
For the majority of people, that’s not really a big deal. Common-cold symptoms tend to be pretty mild and usually resolve on their own after a few days of nuisance. The virus infiltrates the nose and throat, but isn’t able to do much damage and gets quickly swept out. Some people may not even notice they’re infected at all, or may mistake the illness for an allergy—snottiness, drippiness, and not much more. Most of us know the drill: “Sometimes, it’s just congestion for a few days and feeling a bit tired for a while, but otherwise you’ll be just fine,” says Emily Landon, an infectious-disease physician at the University of Chicago. As a culture, we’ve long been in the habit of dismissing these symptoms as just a cold, not enough of an inconvenience to skip work or school, or to put on a mask. (Spoiler: The experts I spoke with were adamant that we all really should be doing those things when we have a cold.)
The general infectious-disease dogma has always been that colds are a big nothing, at least compared with the flu. But gentler than the flu is not saying much. The flu is a legitimately dangerous disease that hospitalizes hundreds of thousands of Americans each year, and, like COVID, can sometimes saddle people with long-term symptoms. Even if colds are generally less severe, people can end up totally clobbered by headaches, exhaustion, and a burning sore throat; their eyes will tear up; their sinuses will clog; they’ll wake up feeling like they’ve swallowed serrated razor blades, or like their heads have been pumped full of fast-hardening concrete. It’s also common for cold symptoms to stretch out beyond a week, occasionally even two; coughs, especially, can linger long after the runny nose and headache resolve. At their worst, colds can lead to serious complications, especially in the very young, very old, and immunocompromised. Sometimes, cold sufferers end up catching a bacterial infection on top of their viral disease, a one-two punch that can warrant a trip to the ER. “The fact of the matter is, it’s pretty miserable to have a cold,” Landon told me. “And that’s how it’s always been.”
As far as experts can tell, the average severity of cold symptoms hasn’t changed. “It’s about perception,” says Jasmine Marcelin, an infectious-disease physician at the University of Nebraska Medical Center. After skipping colds for several years, “experiencing them now feels worse than usual,” she told me. Frankly, this was sort of a problem even before COVID came onto the scene. “Every year, I have patients who call me with ‘the worst cold they’ve ever had,’” Landon told me. “And it’s basically the same thing they had last year.” Now, though, the catastrophizing might be even worse, especially since pandemic-brain started prompting people to scrutinize every sniffle and cough.
There’s still a chance that some colds this season might be a shade more unpleasant than usual. Many people falling sick right now are just coming off of bouts with COVID, flu, or RSV, each of which infected Americans (especially kids) by the millions this past fall and winter. Their already damaged tissues may not fare as well against another onslaught from a cold-causing virus.
It’s also possible that immunity, or lack thereof, could be playing a small role. Many people are now getting their first colds in three-plus years, which means population-level vulnerability might be higher than it normally is this time of year, speeding the rate at which viruses spread and potentially making some infections more gnarly than they’d otherwise be. But higher-than-usual susceptibility seems unlikely to be driving uglier symptoms en masse, says Roby Bhattacharyya, an infectious-disease physician and microbiologist at Massachusetts General Hospital. Not all cold-causing viruses leave behind good immunity—but many of those that do are thought to prompt the body to mount relatively durable defenses against truly severe infections, lasting several years or more.
Plus, for a lot of viruses going around right now, the immunity question is largely moot, Landon told me. So many different pathogens cause colds that a recent exposure to one is unlikely to do much against the next. A person could catch half a dozen colds in a five-year time frame and not even encounter the same type of virus twice.
It’s also worth noting that what some people are categorizing as the worst cold they’ve ever had might actually be a far more menacing virus, such as SARS-CoV-2 or a flu virus. At-home rapid tests for the coronavirus often churn out false-negative results in the early days of infection, even after symptoms start. And although the flu can sometimes be distinguished from a cold by its symptoms, they’re often pretty similar. The illnesses can only be definitively diagnosed with a test, which can be difficult to come by.
The pandemic has steered our perception of illness into a false binary: Oh no, it’s COVID or Phew, it’s not. COVID is undoubtedly still more serious than a run-of-the-mill cold—more likely to spark severe disease or chronic, debilitating symptoms that can last months or years. But the range of severity between them overlaps more than the binary implies. Plus, Marcelin points out, what truly is “just” a cold for one person might be an awful, weeks-long slog for someone else, or worse—which is why, no matter what’s turning your face into a snot factory, it’s still important to keep your germs to yourself. The current outbreak of colds may not be any more severe than usual. But there’s no need to make it bigger than it needs to be.
