By now, it’s abundantly clear that COVID-19 isn’t at all times an sickness that clears shortly and leaves no hint. Tens of millions of individuals within the U.S., and much more world wide, have Lengthy COVID, the identify for signs that final months and even years after an an infection.
Now, a brand new report from the U.S. Facilities for Illness Management and Prevention (CDC) helps quantify simply how typically COVID-19 is linked to subsequent well being points. Amongst U.S. adults youthful than 65 who’ve had COVID-19, roughly one in 5 has developed a well being situation which may be associated to the virus, the report says. Amongst individuals 65 or older, about one in 4 has.
To succeed in these findings, CDC researchers used digital well being data to trace greater than 350,000 U.S. adults who had confirmed COVID-19 instances. They tracked these individuals for as much as a 12 months after their diagnoses to see in the event that they developed at the very least certainly one of 26 situations linked to post-COVID-19 sickness—together with coronary heart illness, respiratory issues, bronchial asthma, kidney illness, neurologic situations, diabetes, and psychological well being situations. For comparability, in addition they tracked a gaggle of 1.6 million U.S. adults who had not had COVID-19, however sought medical take care of different causes throughout the research interval.

From that comparability, it was clear that COVID-19 survivors had been at elevated threat of growing nearly the entire 26 situations. Probably the most dramatic threat variations between COVID-19 survivors and the overall inhabitants had been in growing respiratory signs and pulmonary embolisms, a kind of blood clot that may result in shortness of breath and chest ache. Individuals who’d had COVID-19 had been about twice as more likely to develop each situations.
There have been some limitations to the info. The researchers used one particular digital well being file community, so the affected person base might not be completely consultant of the U.S. inhabitants. It’s additionally potential that docs had been trying extra intently for the analyzed situations in COVID-19 survivors than in those that hadn’t had the virus, or that some individuals had undiagnosed situations earlier than they received contaminated. (Individuals with a documented, latest historical past of one of many 26 situations had been excluded from the research.) The researchers additionally didn’t account for an individual’s COVID-19 vaccination standing, and knowledge assortment ran solely by way of November 2021, so it’s not possible to say how newer COVID-19 variants like Omicron match into the image.
Nonetheless, the research offers much more proof that COVID-19 could cause issues that final for much longer than an acute an infection does. Even when signs like coughing, fever, and fatigue clear up in a matter of days, the virus can depart an enduring mark in ways in which aren’t instantly obvious.
That’s trigger for severe concern, notably given how contagious the at the moment circulating variants are. Nearly 60% of the U.S. inhabitants had been contaminated as of February, in line with CDC estimates, and that quantity is nearly actually a lot larger now. “Because the cumulative variety of individuals ever having been contaminated with SARS-CoV-2 will increase, the variety of survivors struggling post-COVID situations can be more likely to enhance,” the authors of the brand new report write.
These situations might be severe and even debilitating—some with Lengthy COVID have needed to depart their jobs or drastically change their life—and it’s not at all times potential to foretell who will likely be affected. One of the simplest ways to keep away from post-COVID issues, consultants typically say, is to keep away from catching the virus within the first place, and to be vaccinated and boosted should you do.
