Chikungunya Cases Spike in France and Italy

According to the European Center for Disease Prevention and Control, chikungunya is not endemic in mainland EU/EEA. However, since the beginning of 2025, and as of mid-October 2025, two countries in Europe have reported cases of the mosquito-transmitted chikungunya virus disease: France (734) and Italy (364). 

Furthermore, in the Communicable disease threats report, week 42, during the past week, France has reported 34 new locally acquired cases of chikungunya virus disease, and Italy has reported 11.

In Italy, chikungunya cases were confirmed in Carpi, San Prospero, Soliera, Novellara, Cavezzo, Modena, Nonantola, Correggio, Novi di Modena, and Cesenatico.

As of October 19, 2025, the U.S. CDC has not issued a Travel Health Notice regarding Italy's chikungunya outbreak, but the agency does say all travelers to Italy should take steps to prevent mosquito bites.

When departing from the USA abroad, chikungunya vaccines are commercially offered at various travel pharmacies.
