Overview
- Authorities say influenza remains at epidemic levels across nearly all regions, excluding Mayotte and La Réunion.
- Santé publique France reports increasing healthcare use among children since the post‑holiday return, while adult indicators are stable or declining.
- New Institut Pasteur and SpF modelling leans toward a near‑term decline but carries high uncertainty, so a renewed rise in hospital care cannot be ruled out.
- Vaccination coverage is deemed insufficient for target groups, reaching 46.3% overall and 53.3% among people aged 65 and older as of December 31.
- People 65 and older account for more than half of ICU flu admissions with nearly three quarters unvaccinated, and early estimates indicate vaccine effectiveness is moderate but real.
