Chikungunya virus transmission is again increasing in Mayotte. Since 1 January 2026, more than 270 autochthonous confirmed cases have been reported, with an average of about 65 cases per week during the last two weeks of February.
Mayotte also experienced a chikungunya outbreak in 2025, with 1’270 confirmed cases and a peak of 232 cases in epidemiological week 21. The total number of cases was likely underestimated due to limited access to healthcare.
Elevated chikungunya transmission should be considered.
Optimal mosquito protection 24/7, also in cities, this also protects you against other mosquito-borne diseases. Vaccination against chikungunya is not licensed in Switzerland.
For vaccination recommendations, see ECTM statement.
In case of fever:
