France Confirms Second Locally-Acquired Chikungunya Case in the Mainland

France's Chikungunya outbreak, centered in the Indian Ocean, may be connected to the recent reporting of locally acquired cases adjacent to the Mediterranean coast.

A press release from the Occitanie Regional Health Agency, issued on June 16, 2025, confirmed a locally transmitted Chikungunya case in the Hérault Department. 

Since the beginning of May 2025, the Agency has reported 59 travel-related cases in Occitanie.

This Department includes the city of Montpellier, home to about 800,000 people.

The Agency wrote that anyone 'who have visited this town and who have shown signs suggestive of chikungunya since the beginning of May are invited by the ARS to consult their doctor.'

Recently, an indigenous (locally) Chikungunya case was reported in La Crau (Var) on June 11, 2025.

During 2024, over 20 travel-related cases were reported in France, and one local case in Île-de-France (Paris).

If your plans include visiting areas affected by the Chikungunya outbreak in 2025, the French and US health agencies recommend discussing vaccination options with a travel vaccination expert.

Currently, Chikungunya vaccines are approved by various countries and offer a high degree of protection from this mosquito-transmitted disease.
