When you’ve gotten COVID greater than as soon as, as many individuals have, it’s possible you’ll be questioning in case your danger for struggling the lingering signs of lengthy COVID is identical with each new an infection.

The reply seems to be no. The possibilities of lengthy COVID — a set of signs together with exhaustion and shortness of breath — falls sharply between the primary and second infections, based on current analysis.

“It does appear that the chance is considerably decrease the second time round than the primary time round for growing lengthy COVID,” says Daniel Ayoubkhani, a statistician on the Workplace for Nationwide Statistics in the UK, who’s been learning lengthy COVID in that nation.

However the danger doesn’t fall to zero, based on the newest outcomes of an ongoing survey of greater than 500,000 folks within the U.Okay. via March 5.

“The chance of lengthy COVID is considerably decrease, … however it’s nonetheless non-negligible. It is not not possible to develop lengthy COVID the second time in case you did not develop it the primary time. I believe that is the important thing takeaway from our examine,” Ayoubkhani says.

The survey tracked lengthy COVID signs like fatigue, muscle aches, shortness of breath and focus issues. Fatigue and bother concentrating had been the most typical.

Among the many adults within the survey, 4% reported lengthy COVID signs persisting at the least 4 weeks after their first an infection, the survey discovered. In distinction, simply 2.4% of those that hadn’t developed lingering well being issues after their first an infection reported ongoing signs after their second case.

“That is a major discount within the odds,” he says.

The examine did not look at why the chance for lengthy COVID could be decrease from a second an infection than a primary. However Ayoubkhani says there may very well be a number of causes.

For instance, the immunity folks have constructed up from earlier infections might cut back the chance of growing lengthy COVID from the following one. “We do not know that from our knowledge, however that is a speculation,” he says.

One other chance is that the examine excluded those that had gotten lengthy COVID from their first an infection, so those that did not get it from their first an infection could also be innately much less vulnerable to lengthy COVID for some purpose.

“It may have one thing to do with somebody’s predisposition,” he says.

The examine additionally did not look at whether or not a second an infection worsens signs in individuals who have already got lengthy COVID.

Although the examine was performed within the U.Okay., there isn’t any purpose to consider the outcomes would not apply to the U.S., he says.

In reality, the findings are in step with an earlier examine that produced related outcomes by inspecting knowledge from tons of of hundreds of sufferers handled via the U.S. Veterans Administration.

That examine, which was revealed in November, discovered that the chance of nonetheless experiencing well being issues a yr after getting COVID fell from about 10% from a primary an infection to about 6% from a second an infection.

“Undeniably, we’re seeing very, very clearly that for the second an infection the chance is decrease than the primary an infection,” says Dr. Ziyad Al-Aly, an epidemiologist at Washington College in St. Louis who led that examine.

Al-Aly agrees which may be due partially to immunity from the primary an infection. One other issue is that later strains of the virus seem to trigger milder illness, which can make them much less prone to result in long-COVID.

“When folks obtained re-infected they typically obtained re-infected with omicron, which is actually milder,” he mentioned, discussing the outcomes of his examine.

One other attainable affect could also be improved therapies, which lessened the severity of COVID, he says.

Neither examine examined the chance of lengthy COVID after a 3rd or fourth an infection, however Al-Aly hopes that the chance would proceed to say no with every subsequent an infection.

“All this stuff are pointing in the best course that makes me optimistic that sooner or later in time re-infection might add trivial dangers or non-consequential dangers,” he says.

“That is our hope. We do not have knowledge. However that is our hope,” he says.

However Al-Aly notes that as a result of so many individuals are nonetheless catching the virus, the general quantity who’re affected by lingering well being issues continues to extend even when there’s a decrease danger from second infections.

“I kind of liken it to Russian Roulette,” Al-Aly says. “The chances on the particular person degree of getting lengthy COVID after a second an infection versus the primary is decrease for any particular person particular person.”

However he provides, “that danger will not be zero,” and meaning at a inhabitants degree, we nonetheless see a rising variety of circumstances of lengthy COVID in the neighborhood — and a rising burden on caregivers and society.
