What is happening

Metropolitan France is seeing sustained but still focal locally acquired chikungunya transmission, rather than just imported cases. Enhanced surveillance has been in place since 1 May 2026. Santé publique France said in its national bulletin published on 14 October that, as of 12 October, there had been 22 autochthonous transmission episodes totaling 162 cases, and 159 imported chikungunya cases had been detected since the start of enhanced surveillance. Regional bulletins published on 15 October still showed active burdens in several regions, including 52 cases in Occitanie, 22 in Nouvelle-Aquitaine, and 33 in Île-de-France; by contrast, media and social posts on 11 October cited 146 autochthonous cases across 20 clusters, unverified, which appears to reflect earlier data. Santé publique France said investigations and prevention and control measures were ongoing for events that were still active.

Who is affected and how it spreads

Chikungunya is a viral disease spread mainly by Aedes mosquitoes, especially Aedes aegypti and Aedes albopictus. Local spread can start when an infected traveller arrives in a place where these mosquitoes are established and the population is susceptible. It usually causes sudden fever and severe joint pain, and WHO says deaths can occur but are typically rare and are reported more often in older adults and people with severe disease or other health problems. A vaccine is licensed in some countries, but the sources here say it is not a complete public-health solution on its own.
