Prevention: Optimal mosquito bite protection 24/7, also in cities (also against other mosquito-borne diseases such as malaria, Zika, chikungunya).

In case of fever, ensure adequate hydrations and apply paracetamol products. If you have a fever, 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.

In case of fever, malaria should be always ruled out by blood tests.

Note on vaccination against dengue fever with Qdenga®:

The Swiss Expert Committee for Travel Medicine (ECTM) recommends a vaccination with Qdenga® only for travelers from 6 years old who have evidence of previous dengue infection and who will be exposed in a region with significant dengue transmission. For details, see ECTM Statement.
