The surge of COVID reinfections during Omicron onslaught

Thu, 2022-02-17 21:05 — mike kraft

COVID reinfections surge during Omicron onslaught Nature - Immunity acquired through previous infection is less effective against Omicron than against other variants, but the risk of severe COVID-19 remains low. Mallapaty, Smriti nature

Since the Omicron variant of SARS-CoV-2 was first detected, the number of people reinfected with the coronavirus has been rising sharply — a trend that was not observed with previous variants. Researchers say that the new variant is probably driving the surge because it is able to evade the body’s immune defences.
