"We used to say that if you got infected, you had about a 90-day warranty. "Yes, you can get Omicron twice," Stanley Weiss, an epidemiologist at Rutgers School of Public Health, told Yahoo, citing discussions with colleagues in South Africa. Professor Neil Ferguson, of Imperial College London, said: This study provides further evidence of the very substantial extent to which Omicron can evade prior immunity given by both infection or vaccination.. For media inquiries, please contact media@northeastern.edu. It is at least 2.4 times more likely to reinfect people who already had a previous strain of Covid. Whether your immune system contains COVID-19 antibodies after fighting through infection or through natural response to a COVID-19 vaccine booster, it is possible to get reinfected after either of these events. In that time period, Amiji says you'd theoretically be protected from a second infection, "but if that decline in antibody levels is rapid from the [first] infection, then you may not necessarily have enough of the antibodies to prevent a second infection," which he shared in a Northeastern University news piece.

Amiji adds that as vaccines continue to aid an ever-expanding amount of the population in blocking potential viral infections, it makes sense that SARS-CoV-2 strains will likely continue to mutate in response. This variant is currently the worlds most dominant variant and has a growth advantage over BA.1. The CDC says most people with COVID-19 "get better within a few days to a few weeks after infection." But for some, symptoms may last even longer and in other cases may even disappear and then return.

Danish scientists confirmed Tuesday that the BA.2 subvariant can reinfect people who previously had its omicron predecessor, BA.1, though the risk of catching the virus again appears low. With the first "deadlier" variant, we double that mortality rate to 2%. He has written about food and dining for Time, among other publications. If another variant were to arise as more common than Omicron in the spring, there's a chance that the expected lower risk of reinfection within 90 days may be impacted.

Many factors play a role in Omicron's seemingly higher risk of reinfection, said Chakrabarti, including its enhanced ability to evade immunity from past infection or vaccination. Omicron BA.5 Coronavirus Variant Can Reinfect in 4 Weeks, Expert Says Home Healthcare You can now get COVID again within 4 weeks because of the new Omicron BA.5 variant, health expert. As viruses mutate into new variants, they can split off into sub-lineages. For example, theDelta variantcomprises 200 sub-variants. And a Danish preprint study found last month it is possible to have had Omicron's original strain, BA.1, and then get the sub-variant, BA.2.
