This decrease was primarily observed among children aged 2 to 14 (-18%); the caseload among adults remained stable compared to the previous week.Among adults over 15 years of age, diagnoses of influenza/influenza-like illness and gastroenteritis were the most common diagnoses reported during the week of February 20–26.

A 27% increase was observed for the influenza indicator (diagnosis), particularly among people aged 75 and older (+51%). However, this increase appears to have slowed toward the end of the week across various geographic regions (with the exception of the West and Northeast).Treatments for gastroenteritis remained stable (-6%) over the past week, except among people aged 75 and older, for whom a 30% increase was recorded compared to the previous week.Activity related to bronchiolitis remains stable over the period, with case numbers similar to those recorded in the two previous seasons (2010–2011, 2009–2010). The measles indicator is stable over the period.

Following an increase in deaths certified by associations during the week of February 13–19, case numbers decreased during the preceding week (February 20–26), but remain higher than those recorded in the two previous years for the same period. This trend in mortality is particularly evident in the North, Central-East, Southeast, and Southwest regions. It is consistent with the trend observed at the national level based on the mortality surveillance system using INSEE data.
