France's Mediterranean Confirms 90% More Local Dengue Cases

The Mediterranean coast of France is known to many vacationers for its lovely scenery and world-class resorts. In 2023, southern Europe alone accounted for about 500 million arrivals. 

However, in 2024, mainland France may experience a record number of mosquito-transmitted diseases, mainly along the Mediterranean.

As of October 30, 2024, Public Health France reported over 4,000 imported cases of dengue, 18 of chikungunya, and 5 of Zika virus in 2024.

Furthermore, the European CDC recently confirmed that 82 locally-acquired dengue cases have been reported in Var (38), Alpes-Maritimes (19 cases), Vaucluse (18), and other departments.

While France has not yet declared dengue endemic, cases in 2024 have eclipsed the entire 2023 mosquito season. In 2023, France only reported 45 autochthonous (local) dengue infections.

From a disease prevention perspective, chikungunya and dengue have approved vaccines available, but Zika vaccine candidates have yet to be authorized in 2024.

While the U.S. CDC does not suggest these vaccines when visiting France, they are generally available in 2024. The CDC  recommends that international travelers speak with a vaccine expert at least one month before traveling abroad.
