The European Centre for Disease Prevention and Control (ECDC) reported that since the beginning of 2025, and as of late January, over 5,000 Chikungunya virus disease (CHIKVD) cases and two related fatalities have been reported in three countries in the Region of the Americas (Brazil, Paraguay, and Colombia) and one in Europe.

While the ECDC has not had any autochthonous (local) cases of CHIKVD in mainland Europe in 2025, 138 cases have been reported from the French overseas department of La Réunion, located off the east coast of Africa.

In 2024, about 620,000 CHIKVD cases and 213 related fatalities were detected in countries in the Americas (15), Asia (6), Africa (1), and Europe (1).

As of February 5, 2025, one Chikungunya vaccine has been approved in Europe, the United States, and the United Kingdom. Valneva SE's IXCHIQ® Chikungunya vaccine is recommended for most travelers visiting outbreak areas.
