Optimal mosquito protection 24/7, also in cities (also against other mosquito-borne diseases such as Zika, dengue).

Two vaccines against chikungunya are licensed in Europe but not yet in Switzerland: Ixchiq® (live-attenuated vaccine and Vimkunya® (virus-like particle vaccine). The Swiss Expert Committee for Travel Medicine is currently preparing a statement. The US CDC has published the recommendations, see LINK.

Of note: The French National Authority for Health (HAS), and the U.S. health authorities currently do not recommend Ixchiq® vaccination for individuals over 65 years of age, as a small number of possible adverse reactions in this age group are under investigation.

In case of fever:

• Ensure adequate hydration and take paracetamol products. Stronger pain killers may be necessary in case of arthropathy.

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.
