According to the French National Health Authority, up to 9 March 2025, 8’749 cases (around 8’600 in 2025) of autochthonous chikungunya virus disease have been reported in La Réunion. In week 10, 2’888 new confirmed cases were reported, representing a 29% increase compared with the previous week. Cases have now been reported in all municipalities. The municipalities reporting the most cases since the start of the epidemic are those in the south, particularly Le Tampon.
On 21 March 2025, two deaths were reported in older adults, one of whom presented with comorbidities.
Optimal mosquito protection 24/7, also in cities (also against other mosquito-borne diseases such as Zika, Dengue).
In case of fever, ensure adequate hydration and apply paracetamol products. If you have a fever, avoid taking medications containing acetylsalicylic acid (e.g., Aspirin®), as this can increase the risk of bleeding during certain viral infections. However, do not stop taking medications containing acetylsalicylic acid if it is already part of your regular treatment for an underlying condition.
Vaccination against chikungunya is licensed in Europe but not yet in Switzerland.
