It says its definition of suspected reinfection is a positive PCR test 90 days (three months) or more after a previous PCR test. Pia MacDonald, PhD, infectious disease epidemiologist at RTI International, a nonprofit research institute, said that this research shows how transmissible the Omicron variant was compared to previous coronavirus variants like Delta. Second, immunity against Covid - either built from previous infection or vaccination - wanes over time. However, a. Photos by Matthew Modoono/Northeastern University. "Typically reinfections are only considered if there is a time gap of at least 90 days between the initial infection and the reinfection. Amiji says COVID-19s subvariants typically cause more upper respiratory issues than lower, making the symptoms less serious. 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.
