Lengthy COVID Danger Makes It Value Avoiding Second Infections


Dec. 19, 2022 — Alexander Truong, MD, has been seeing lengthy COVID sufferers for greater than 2 years however thought the numbers would have considerably dwindled by now. As a substitute, a gradual circulation of sufferers nonetheless reveals up on the Emory Government Park post-COVID clinic he and a colleague launched in fall 2020 in Atlanta. And amongst sufferers contaminated greater than as soon as, the signs seem worse.

“We’re undoubtedly seeing quite a lot of sufferers who, once they get reinfected, have worsening post-COVID points. That’s very true and I believe that’s an enormous sign,” says Truong, a pulmonologist and an assistant professor at Emory College’s Faculty of Medication.

COVID-19 is certainly not over, says Angela Cheung, MD, PhD, a senior doctor scientist with the College Well being Community and a professor of drugs on the College of Toronto. And every time somebody will get contaminated, they danger growing lengthy COVID. A previous an infection doesn’t erase the chance, Cheung says.

“It’s not like, ‘Oh, I’ve had one, so it’s OK. Now I can take off my masks, do what I like.’ It has well being penalties for reinfections – increased mortality charge, increased hospitalization charges, increased danger of long run, lingering signs,” she says.

New analysis means that these contaminated greater than as soon as have an elevated danger of growing lengthy COVID and different well being issues in comparison with these contaminated simply as soon as. However parsing out the extent of those dangers – notably with newer variants – is extra difficult, Truong and different consultants say, notably when factoring in vaccinations and antiviral remedies. 

“It is smart that repeat infections wouldn’t be useful to an individual’s well being. However I believe it is actually exhausting to know what the extra danger of every subsequent an infection could be as a result of there are all types of different issues within the combine,” says Michael Peluso, MD, an assistant professor of drugs and an infectious ailments physician on the College of California San Francisco.

“There are vaccines — new vaccines, previous vaccines. There are variants — previous variants, new variants, and now a number of variants circulating on the identical time.”

Veterans Affairs Research

A big examine involving the data of 5.8 million Division of Veterans Affairs sufferers that was printed in Nature Medication in November discovered that sufferers contaminated greater than as soon as had considerably increased dangers of dying, hospitalization, coronary heart issues, blood clotting, lengthy COVID, and a bunch of different well being points and organ injury. Notably, the examine discovered that these elevated dangers remained even 6 months after reinfection.

Whereas the examine highlights the elevated dangers related to reinfections, it has its limitations. The examine didn’t straight evaluate a primary an infection to reinfection inside the identical pool of sufferers. It solely in contrast one group of people who had a single an infection to a separate group who had multiple an infection. 

There could possibly be different components that made one group extra vulnerable to reinfection and at better danger of opposed well being outcomes. The examine additionally didn’t evaluate reinfection dangers between completely different variants or subvariants.

One other limitation is the VA inhabitants itself. The VA database is extraordinarily helpful for big research like this one as a result of it follows numerous individuals with complete medical data, consultants say, however the VA’s inhabitants of largely older white males doesn’t replicate the demographics of the final inhabitants.

Nonetheless, the message for the general public is easy, says Cheung. “I wouldn’t get into the weeds. The large message and large image is that reinfections are unhealthy.”

Completely different Dangers With New Variants?

Consultants say understanding reinfection dangers, notably with the newer variants and subvariants, is difficult as a result of extra individuals at the moment are vaccinated in comparison with earlier within the pandemic.

“There usually are not any definitive solutions. … It’s very, very tough to disentangle the emergence of recent variants from the uptake of vaccines,” says Peluso.

“It does seem to be total there could also be much less lengthy COVID with the newer variants, however it’s very exhausting to say whether or not that may be a attribute of the virus or a attribute of the truth that most people who find themselves getting the virus have both been vaccinated or beforehand contaminated to have some completely different immune baseline from any individual who’s seeing the viral antigen for the primary time.”

Nonetheless, consensus is rising that those that are vaccinated and find yourself with breakthrough infections are at decrease danger of growing lengthy COVID. One U.Okay. examine printed within the journal Open Discussion board Infectious Ailments in September, for instance, discovered that individuals who had two COVID-19 vaccinations at the very least 2 weeks previous to an infection had a 41% lower within the odds of growing lengthy COVID signs, in comparison with individuals who weren’t vaccinated on the time of an infection.

“We additionally know that in sufferers who’ve had their vaccinations, they’re much less prone to have a reinfection, or once they do have reinfection, they’re much less prone to have extreme an infection,” says Truong.

“That’s the one large sign that we’ve got and that’s why I am making an attempt to wave the flag as a lot as I can about getting vaccinated [and boosted].”

Whereas some information suggests the dangers of lengthy COVID are decrease with Omicron variants in contrast with the Delta variant, consultants level out {that a} far better variety of individuals have been contaminated with Omicron, so even a small share of a big quantity continues to be a big quantity. 

One examine taking a look at Omicron versus Delta reveals about half the chance, however half the chance in much more individuals continues to be quite a lot of excessive absolute numbers,” Cheung says, referring to a June paper printed in The Lancet

She nonetheless sees quite a lot of sufferers with lengthy COVID – some contaminated as not too long ago as this previous summer time, some vaccinated and contaminated for the primary time, and others coming in following reinfections.

And whereas Omicron variant and subvariant infections could seem milder for many individuals, docs be aware new sufferers are additionally displaying up with the identical debilitating signs as those that bought lengthy COVID earlier within the pandemic: fatigue, shortness of breath, racing coronary heart, mind fog, sleep disturbances, and psychological well being points.

“On my post-COVID clinic days, I’m nonetheless seeing 4 to eight new sufferers who had infections in 2022 are available with important signs,” says Truong.

And lengthy COVID can kill. Greater than 3,500 dying certificates filed from the beginning of the pandemic by June 2022 listing lengthy COVID as a selected reason behind dying, the Nationwide Heart for Well being Statistics reviews.

Minimizing Put up-COVID Dangers

Peluso says what may be realized from the VA examine is that repeated assaults on the immune system are harmful and that persevering with to keep away from an infection stays extraordinarily essential.

“One of the best ways for somebody to guard themselves towards that’s to keep away from getting COVID within the first place,” says Peluso. It’s a sentiment echoed by Truong and Cheung.

However given the transmissibility of the most recent variants and subvariants and the elimination of public well being measures, it’s typically tough to forestall an infection. Tried and true instruments do, nevertheless, work: being updated on vaccinations, sporting high-quality, well-fitted masks, advocating for good air flow, and conducting self-testing with fast antigen exams, notably forward of indoor occasions throughout busy vacation durations.

“It’s attainable that this may occasionally develop into much less widespread over time. I hope that’s true,” Peluso says. 

“It’s additionally attainable that it would go the opposite method. And so for that cause, I’m making an attempt to keep away from all the variants.”
