Health Monitoring in the Grand Est Region. Bulletin of November 27, 2025.

Key points

Bronchiolitis

  • Visits to emergency rooms and SOS Médecins consultations related to bronchiolitis have been on the rise since week 46. Virology data indicate an increase in the circulation of RSV in the region. These factors have led to the Grand Est region entering the pre-epidemic phase.

Influenza and influenza-like illnesses

  • Indicators for influenza-like illnesses remain at baseline levels. Virological data show a few sporadic cases of influenza, as expected at this time of year.

COVID-19

  • Healthcare utilization for suspected COVID-19 remains stable at a low level (<1% of total activity) in both primary care 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.
