Key Points

• The circulation of influenza viruses is increasing in France; the epidemic threshold was crossed for the first time this week.

• The RSV bronchiolitis epidemic is beginning to subside.

• Activity related to acute gastroenteritis during week 51 is increasing in community settings and remains stable in hospitals compared to the previous week.

• Thresholds were exceeded across the entire region for emergency room visits and SAMU cases, with no notable effect on hospitalizations—a typical occurrence at this time of year, due to the combination of seasonal illnesses and the closure of many doctors’ offices.
