In Week 51, in Normandy, the spread of Covid-19 accelerated further, with the regional incidence rate (IR) rising to 474 per 100,000 inhabitants, a 57% increase compared to the previous week. This increase is particularly pronounced among those aged 20–39. On December 27, 55.1% of screening tests indicated a profile consistent with Omicron.

Flu

Non-epidemic phase, on the rise: In week 51, the proportion of emergency department visits for flu-like symptoms remained low. The number of consultations was stable and at a level similar to that of 2019–2020.

Nevertheless, the number of influenza viruses detected by virology laboratories in the region was rising sharply (20 at Rouen University Hospital and 5 at Caen University Hospital). A first case of severe influenza requiring hospitalization in an intensive care unit for the 2021–2022 season was reported.
