Apply optimal mosquito protection 24/7, this also protects you against other mosquito-borne diseases. In addition:
- Yellow fever vaccination is highly recommended for stays <2500 elevation in Bolivia.
- Chikungunya vaccination is recommended!
- Zika: Pregnant women, partners of pregnant women, or if you or your parent is planning to become pregnant: refer to the specific recommendations in EpiNews (23.04.2026).
- Dengue vaccination: see ECTM statement.
In case of fever:
- Get tested to rule out malaria!
- Ensure adequate hydration and apply paracetamol products for symptomatic treatment.
- Avoid taking medications containing acetylsalicylic acid (e.g., Aspirin®), as this can increase the risk of bleeding during a dengue infection. However, do not stop taking medications containing acetylsalicylic acid if it is already part of your regular treatment for an underlying condition.
