If You Get the Coronavirus and Recover Can You Get It Again
As the latest COVID-xix surge begins to subside in the U.S., some people may find themselves recovering from a coronavirus infection or fifty-fifty reinfection.
That's because as the virus mutates and protection wanes, it becomes more possible to be reinfected by the coronavirus. But experts say that, while getting COVID-19 tin provide some protection against a future coronavirus infection, it's much safer to rely on vaccines and boosters for that protection instead.
Tin you get reinfected with the coronavirus?
Yep, it's definitely possible to become COVID-19 more than than once.
"Even before the virus started to turn into different variants, even with the original strain that was circulating, there were already many documented cases of people getting reinfected," Dr. Otto Yang,professor of medicine in the division of infectious diseases and of microbiology, immunology and molecular genetics at the David Geffen School of Medicine at UCLA, told TODAY.
That's not peculiarly surprising considering that nosotros tin can be infected and reinfected past the regular pre-COVID coronaviruses that cause the mutual cold within a year, he said.
As more variants emerge, reinfections merely go more likely because those variants tin potentially evade the immune protection nosotros already have. "If you had delta, you can become omicron — definitely," Dr. Bernard Camins,medical director for infection prevention at the Mount Sinai Health Organization, told TODAY. And the contrary is truthful as well; if you had an infection with the omicron variant, you can still go delta. That's because "the fasten poly peptide of the delta variant is very dissimilar from the spike protein of omicron," Camins said.
The coronavirus fasten protein is what the virus uses to infect human cells. Antibodies that yous might develop after a previous COVID-xix infection "have to bind to a really specific expanse of the spike protein to block the virus," Yang explained. If the spike poly peptide keeps irresolute in meaning ways, antibodies aren't as able to do their jobs to protect you from infection.
So, tin you become omicron more than than in one case? Earlier in the pandemic, there were definitely cases of reinfection with the same variant. Only when it comes to omicron reinfections specifically, that's something researchers are still figuring out. And we probable won't know how mutual that scenario is for a few more months, Camins said.
How astringent are COVID-19 reinfections?
Generally, reinfections are milder than the initial infection regardless of which variants you're infected with, the experts said.
And even if you are infected with a different variant the 2nd time around, you shouldn't necessarily look more severe symptoms. That's partly because, fifty-fifty if your antibodies aren't able to muster plenty protection confronting getting infected, the protection from your T-cells — another major player in the immune organisation — volition still help protect you from the most severe consequences of the disease fifty-fifty if you go infected, Yang said.
"T-cells are not restricted by recognizing any one surface area of the spike," he said. "They're not really afflicted as much or at all by different variants. They should human action just as well confronting omicron as against delta as against the prior variants."
But Camins notes that what experts may define as a "mild" infection tin yet feel subjectively awful — and, of course, crusade disruptions in your daily life. "In virtually cases, the symptoms are less severe, pregnant your likelihood of death or astringent illness is lower," he said. Simply if your symptoms cause y'all to miss work for a prolonged period of time or it takes yous a few weeks to recover, "that's still pretty significant" fifty-fifty if it doesn't transport you to the hospital.
And at that place is still the small hazard that you may experience severe symptoms or complications — or that yous'll spread the virus to someone with a weakened immune system or other underlying status that puts them at a higher risk.
How long does amnesty from a previous COVID-xix infection last?
Equally the experts explained in a higher place, having had COVID-19 in the past volition protect you to some degree from reinfection in the hereafter.
In general, the experts said that y'all'll have some protection for about three to six months subsequently a COVID-19 infection. But the protection yous'll get from this type of "natural immunity" can exist unpredictable, Yang said.
People who have more severe bouts of COVID-19, pregnant people who are hospitalized, typically end up with more than robust protection from the virus, he explained. Just on the other hand, that as well probably means they have a take a chance gene that made it more than likely for them to get COVID-19 in one case — and people in that situation really don't want to become information technology again.
And a CDC study published in November underscores but how much better it is to become protection through vaccination than infection: Among seven,300 patients hospitalized with symptoms like those of COVID-nineteen, those who were unvaccinated but had previously had the illness were five times more than likely to examination positive for the infection than those who were vaccinated (and didn't have any record of a previous COVID-nineteen infection).
Of form, getting that protection via infection also comes with the risks for long-term consequences of COVID-19 besides as hospitalization and even death. So, if you had COVID-19 and aren't vaccinated, it's still worth getting the shots to protect yous in the futurity.
What can you practise to forestall reinfections?
To prevent COVID-19 reinfections, yous can use the aforementioned public wellness strategies that we know can aid prevent an initial coronavirus infection. That includes getting vaccinated and boosted, wearing a mask in public (especially an N95 or KN95 respirator, Camins said), getting tested when appropriate and focusing on ventilation.
But some people are more than likely to get COVID-19 and also, therefore, to get it more than once. That includes those with certain underlying atmospheric condition or who are taking medications that suppress the immune system, such equally those with uncontrolled diabetes or autoimmune diseases as well equally those undergoing chemotherapy.
Reducing the amount of the virus that's circulating in your community will go on you and those around y'all safer, including those who might have chance factors that could make COVID-nineteen more than severe for them. "It's non necessarily just most you," Yang said. "Information technology may exist that you lot had mild COVID and that if you lot get infected once more, it will be mild COVID. But we should be thinking every bit a society virtually everybody."
