Optimum protection against mosquito bites around the clock, even in cities (during the day against dengue, chikungunya, Zika, in the evening and at night against malaria). In case of fever: paracetamol products and hydration. Avoid taking medicines containing acetylsalicylic acid (e.g. Aspirin®) if you have a fever, as this can increase the risk of bleeding during a dengue infection. However, do not stop taking medication containing acetylsalicylic acid if it is already part of your regular treatment for an underlying condition.
Note on vaccination against dengue fever:
The Swiss Expert Committee for Travel Medicine (ECTM) recommends vaccination with Qdenga® only for travellers aged 4 years and older with confirmed previous dengue infection AND who will be exposed to a region with significant dengue transmission.
