Published

Santé publique France released a bulletin on 12 November 2026 reporting 31 episodes of locally acquired chikungunya, one more than the previous week. They total 214 cases as of 9 November.

The bulletin also records five dengue episodes totalling eight cases, with no additional weekly episode. It reports 222 West Nile cases classified as locally acquired, ten more than previously, while flagging uncertainty over one case’s classification.

These figures describe infections detected by surveillance rather than all infections. L’Appel notes that symptom-free infections were found among blood donors. Investigations and control measures continue around active events, according to the health agency.
