China: Chikungunya cases in Guangdong Province have surpassed 8’000, with Foshan the most affected city. New daily cases are declining. Cases have also been detected in 12 other cities.
Macao: In July and August 2025, Macao reported increasing number of imported and two locally transmitted cases of chikungunya fever, marking a large epidemiological shift for the area where the virus is not endemic.
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: Vimkunya® (virus-like particle vaccine) and Ixchiq® (live-attenuated vaccine. The Swiss Expert Committee for Travel Medicine is currently preparing a statement. The US CDC has published the recommendations, see LINK.
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.
