Key Points

COVID-19

• Although on the rise, COVID-19-related activity in emergency departments remains low and is in line with observations from previous years during the same period. Activity among SOS Médecins associations is also low. According to the virology laboratory at Rennes University Hospital, SARS-CoV-2 circulation has remained stable over the past few weeks (10% of samples tested positive). Circulation is very low, according to the virology laboratory at Brest University Hospital (< 1%).

Bronchiolitis (Under 1 year)

• Non-epidemic activity. Activity related to bronchiolitis remains low in hospital emergency departments, with emergency department visit rates lower than in previous years during the same period. The Virology Laboratory at Brest University Hospital (CHU) has sporadically detected RSV among the respiratory specimens analyzed (no detections reported by Rennes University Hospital). 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 have remained low and stable over the past few weeks in hospital emergency departments. The virology laboratories at the Brest University Hospital (CHRU) and the Rennes University Hospital (CHU) have been sporadically detecting influenza A viruses for several weeks.
