Overview
- Santé publique France reports all mainland regions at epidemic level, with La Réunion in pre‑epidemic phase.
- Influenza‑like illness consultations rose to 349 per 100,000 people for Dec. 15–21, up from 282 the prior week, and SOS Médecins estimates flu at 19.28% of visits.
- The increase spans all ages but is most pronounced in children under 15, and hospitalizations after emergency visits have reached moderate intensity across age groups.
- As of Nov. 30, vaccination coverage was 38.1% among targeted groups, 44.2% in those 65+, and 21.3% in at‑risk adults under 65, with 30% of vaccinated seniors receiving enhanced vaccines.
- Virologists identify H3N2 subclade K as dominant with partial immune escape that raises transmissibility, and modeling suggests the epidemic peak could arrive within the next two weeks.
