- Local media report a Chikungunya outbreak in Chittagong, the second largest city in Bangladesh, with around 2100 cases recorded from January to mid-August 2025.
- High mosquito density and insufficient mosquito control are worsening the spread.
- Public health concerns increase due to limited routine surveillance and diagnostic difficulties.
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.
