Corsica France Confirms Third Chikungunya Case of 2025

The French Health Ministry has been reporting a significant number of locally acquired chikungunya cases in its Department in 2025. ARS Corsica states that the presence of the virus-carrying tiger mosquito is now well established in southern Corsica and throughout Europe.

As of July 2, 2025, a third locally acquired case of chikungunya has been detected in southern Corsica, in Porticcio (municipality of Grosseto-Prugna).

In late June 2025, ARS Corsica reported two cases of chikungunya from the same family, residing in Grossetto-Prugna.

On France's mainland, the Occitanie Regional Health Agency detected a locally transmitted case of Chikungunya in the Hérault Department on June 16, 2025. Another case was reported in La Crau (Var) on June 11, 2025.

Additionally, the Departments of Reunion and Mayotte in the southern India Ocean have been confronting chikungunya outbreaks over the last few months.

From a health protection perspective, chikungunya vaccines are now commercially available in France and the United States. 

The U.S. CDC recommends that international travelers visiting areas with chikungunya outbreaks speak with a travel vaccine expert about immunization options.
