There’s a purpose why persons are nonetheless vulnerable to catching SARS-CoV-2 months after recovering from COVID-19, and it has one thing to do with how the virus developed from the time the pandemic began.

It’s widespread for everybody to assume that they’ve gotten resistant to the virus after battling its illness as soon as. But pecialists clarified that because of the variations within the newer strains, it’s very probably for COVID-19 survivors to contract the virus once more. 

People who caught the illness earlier than the arrival of omicron developed an 84% decrease threat of reinfection, particularly within the months proper after battling the virus, as per NPR

However, the subvariants that got here after omicron modified the best way transmissions work. With the newer mutations within the virus, SARS-CoV-2 has develop into extra transmissible and superb at evading immunity, whether or not from prior an infection, vaccination, or each. 

The newer omicron subvariants have develop into able to evading safety afforded by earlier non-omicron variations of the virus. This makes it attainable for former sufferers to catch the newer subvariants even when they’d the unique omicron variant earlier than. 

It can also be essential to notice that safety from a previous an infection wanes over time. Hence, those that battled COVID-19 earlier than are nonetheless inclined to reinfection a couple of months later. 

In February, researchers discovered that COVID-19 reinfections were rising because of the emergence of newer strains with extra mutations than the earlier virus variations. They insisted that reinfections needs to be much less extreme than main infections. 

The newest knowledge on COVID transmissions appeared to agree with what the researchers mentioned. Though the newer strains are extra transmissible and fewer inclined to vaccines, they trigger much less extreme sickness and fewer deaths, particularly among the many vaccinated, in line with The New York Times

“Both natural infection and vaccination seem to provide good protection against severe outcomes in most individuals,” Juliet Pulliam, the director of the South African Centre for Epidemiological Modelling and Analysis, informed NPR.

Repeat infections aren’t preventable, so consultants have been urging everybody to deal with strengthening their immunity by way of vaccination. For previously hospitalized COVID-19 sufferers, getting the two-dose mRNA vaccines would give them at the least 35% safety from subsequent hospitalizations. Getting a booster would improve this to 68%.
