France's Local Chikungunya Cases Centered Around Marseille

The French Republic has been confronted with significant chikungunya outbreaks in various Departments in 2025.

As of July 9, 2025, Sante Publique France reported a total of 25 locally acquired cases of chikungunya in the mainland since May 2025.

Mosquito-transmitted cases have been reported from Provence-Alpes-Côte d'Azur (PACA) (14), Corsica (3), Occitanie (2), Auvergne-Rhône-Alpes (4), Grand Est (1), and Nouvelle-Aquitaine (1).

Located at the far southeastern point of the mainland, PACA's largest city is Marseille, France's third-largest city, with over 800,000 residents, and a tourist favorite destination.

In addition to local cases, France has reported 761 imported cases of chikungunya in the last few months.

Many of these cases are related to international travel to France's Department of Reunion and Mayotte in the southwest Indian Ocean.

In France, as well as in the United States, chikungunya vaccines are commercially offered. Various governments have approved these vaccines and provide a high degree of protection against this mosquito-transmitted disease.

The U.S. CDC recommends vaccination before visiting areas with chikungunya outbreaks, such as the southern regions of France.
