Health Surveillance in Normandy. Bulletin of December 3, 2025.

Key points

Bronchiolitis

  • Normandy is in the midst of a bronchiolitis epidemic for the third consecutive week. Most indicators are rising sharply (hospitals, hospital laboratories), reaching the highest levels of the previous season. However, the epidemic has leveled off in urban areas (SOS-Médecins) with a decrease in the number of consultations.

Influenza and Flu-Like Illness

  • Normandy has entered an epidemic phase for influenza. All indicators are on the rise (emergency rooms, SOS Médecins, the Sentinelle + IQVIA network, private and hospital laboratories), reaching moderate levels typical of the start of an epidemic wave. The viruses detected by hospital laboratories are type A, with H1N1 and H3N2 circulating simultaneously.
