After a lull, here she is back. The flu epidemic continues to progress in France and has now spread to almost all of France, including the Paris region where it is resuming after declining at the start of the year, shows the weekly report from Public Health France on Wednesday March 16. The past week has been marked by a “sharp increase in all the indicators [de la] flu” in France, summarizes the public health agency, noting that now “all metropolitan areas [sont] in epidemic, except Corsica”.
This includes Ile-de-France, which, hit by the epidemic from the end of 2021, had experienced a lull at the start of the year and was no longer considered to be in the epidemic phase. She went back there this week. Outside mainland France, Guyana was also hit by the flu epidemic, but the other French overseas departments and territories were spared.
This flight of the flu is unusually late. In recent years, the peak of the epidemic (measured by the consultation rate in relation to the number of inhabitants) took place in February.
Winter 2020-2021 was however special, due to the containment measures taken against Covid-19. They had, by extension, made it possible to block the circulation of many other microbes, such as the flu virus. But the French, less infected than usual, are also less immunized collectively, which favored a resumption of the epidemic this winter.
However, this remains below the levels observed in 2019-2020, just before the health crisis.
