Key Points

COVID-19

• SOS Médecins continues to see a decline in activity that began in Week 41, though the decline is less pronounced than that between Weeks 41 and 40. This decline is also evident, to a lesser extent, in emergency departments. Activity rates for both sources remain low compared to the same period in previous years.

Bronchiolitis (Under 1 year)

• Non-epidemic activity. At the start of the winter surveillance period, activity related to bronchiolitis remains low in both hospital and community emergency departments and has remained generally stable since Week 39. The virology laboratories at the two Breton university hospitals have not detected RSV in the respiratory specimens tested. However, other viruses capable of causing bronchiolitis are circulating, notably rhinoviruses.

Influenza and Flu-Like Illness

• Non-epidemic activity. The monitored indicators for influenza and influenza-like illnesses remain low as winter surveillance resumes, both in hospital emergency departments and at SOS Médecins. The virology laboratories at the Brest University Hospital (CHRU) and the Rennes University Hospital (CHU) have been sporadically detecting influenza A viruses for the past few weeks.

Gastroenteritis

• Activity is considered low based on emergency department data and moderate based on SOS Médecins data. The number of emergency department visits remains stable, while, at the same time, SOS Médecins consultations continue to rise. Activity rates are higher than those of the past two seasons, both in emergency departments and at SOS Médecins.
