Overview
- Health surveillance shows nearly all metropolitan regions in the epidemic phase, with Corsica still pre-epidemic and Martinique and Guadeloupe not yet in epidemic status.
- Pediatric services are saturated in Île-de-France, Hauts-de-France and Normandie, prompting transfers mainly to CHU Rouen and CHU Reims.
- Between November 24 and 30, almost 3,000 infants were seen in emergency departments and 974 were hospitalized for bronchiolitis.
- Laboratories report increasing detection of respiratory syncytial virus in nasopharyngeal samples from community and hospital settings.
- Preventive options Beyfortus and the maternal vaccine Abrysvo have confirmed safety from ANSM, yet mid‑November uptake was about 46% in a key infant cohort and pediatricians are urging immunization.
