Just because you've had the coronavirus doesn't mean you're immune.

The numbers remind us.

Recently, the number of people reinfected with Covid-19 has increased significantly.

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 cases of reinfection that have occurred since March 2021 were indeed "suspected Omicron variant".

Despite a high number of reinfections with an Omicron subvariant after a first infection with another Omicron subvariant (44% of cases), "the probability that a reinfection will actually occur after a first infection with a other variant (Alpha, Delta or other)" "remains significantly higher", underlines the agency.

In addition, "the further the first contamination is in time, the more the probability of reinfection will increase", specified Vincent Auvigne.
