Southern France Reports Additional Locally-Acquired Chikungunya Cases

Sante Publique France reported today that a total of eight locally acquired cases of chikungunya have been confirmed in southern France since late May 2025. 

Cases in France's mainland were reported in Occitane (Hérault and Gard), Provence-Alpes-Côte d'Azur (Var and Bouches-du-Rhône), Auvergne-Rhône-Alpes (Drôme), and on the island of Corse (Corse-du-Sud).

Although declining as of June 25, 2025, the number of chikungunya cases that have traveled to Réunion and the Indian Ocean remains high. It contributes to the early appearance of indigenous transmission.

Additionally, 645 imported cases of chikungunya have been reported over the past nine weeks.

The government says, 'This number of episodes has never been observed in France before.'

Public Health France reiterates the importance of protective measures against mosquito bites, the control of larval breeding sites, and the use of protective vaccination, if appropriate.
