"That is to say if you had Omicron you can still get infected with BA.2," says Furness. Studies suggest that reinfection with SARS-CoV-2 with the same virus variant as the initial infection or reinfection with a different variant are both possible; early reinfection within 90 days of the initial infection can occur. The idea that if you are infected, that you dont necessarily have to worry about reinfection for three months, doesnt necessarily apply anymore, he says. Additionally, the BA.2.75, an omicron subvariant with many mutations, is expected to be the next variant casing a wave, according to inewsource.
