Key Points

COVID-19

In the Pays de la Loire region, the spread of Covid-19 continues, with a significant impact on the healthcare system and the demand for medical care.

Bronchiolitis

The Pays de la Loire region has been in the bronchiolitis epidemic phase since Week 41, marking the 9th consecutive week in Week 49, in line with other metropolitan regions (see map opposite). A trend toward stabilization, or even a decrease, in healthcare utilization for bronchiolitis among children under 2 years of age was observed in Week 49, though levels remain high and well above alert thresholds. These healthcare visits are linked to the sharp increase in RSV circulation reported by the virology laboratories at the Nantes and Angers University Hospitals in weeks 47 and 48, which also stabilized in week 49.

Influenza

The Pays de la Loire region is not currently in a pre-epidemic phase. Emergency department visits for influenza-like illness were stable and relatively low in week 49, at levels typically observed at this time of year. An increase in influenza A isolates among children was reported in week 49 by the region’s virology laboratories.

Acute gastroenteritis

A marked increase in emergency department visits for acute gastroenteritis, particularly affecting children under 5 years of age.
