Health Monitoring in the Grand Est Region. Bulletin of December 4, 2025.

Key points

Bronchiolitis

  • Bronchiolitis indicators continue to rise for the third consecutive week, reflecting increased viral circulation in the region. It accounts for 15% of emergency room visits and 8% of SOS Médecins consultations in the region among children under 1 year of age. The region has been classified as being in an epidemic phase, like the rest of mainland France.

Influenza and Influenza-Like Illnesses

  • In week 2025-48, activity for influenza-like illness is on the rise in emergency departments (accounting for less than 1% of visits) as well as at SOS Médecins clinics in the region (accounting for approximately 7% of consultations). Virology data indicate a resurgence of influenza A viral circulation. These factors have led to the region being classified as being in a pre-epidemic phase for influenza.

COVID-19

  • Seekings of care for suspected COVID-19 remain stable at a low level (<1% of total activity) in both private practice and hospitals.

Acute gastroenteritis

  • In the SOS Médecins network, consultations for acute gastroenteritis have shown an upward trend in recent weeks, though they remain within the usual seasonal fluctuations.
