Just because you’ve had the coronavirus doesn’t mean you’re immune. The numbers remind us. Recently, the number of people re-infected with Covid-19 has increased dramatically. Thus, 12% of confirmed cases of Covid-19 were possible cases of reinfection, Public Health France indicated on Friday in its weekly update. Between March 2, 2021 and June 12, 2022, possible reinfections accounted for 4.1% of all confirmed Covid-19 cases.
“The increase has been continuous since the arrival of the Omicron wave”, commented Vincent Auvigne, epidemiologist from Public Health France, during a press briefing. The vast majority (93.5%) of reinfection cases occurring since March 2021 were indeed “suspected Omicron variants”.
Despite a high number of reinfections with a subvariant of Omicron after a first infection with another subvariant of Omicron (44% of cases), “the probability that a reinfection actually occurs after a first infection with a other variant (Alpha, Delta or other)” “remains clearly superior”, underlines the agency. In addition, “the further the first contamination is in time, the more the probability of reinfection will increase”, specified Vincent Auvigne.
