In 2025 and as of 16 July 2025, 4 locally transmitted cases have been reported from 3 European countries: Portugal (2), Italy (1), France (1).
Optimal mosquito protection 24/7, also in cities (also against other mosquito-borne diseases). Vaccination
against dengue is not routinely recommended for residing or traveling in European countries.
Note on vaccination against dengue fever with Qdenga®:
- The Swiss Expert Committee for Travel Medicine (ECTM) recommends a vaccination with Qdenga® only for travelers older than 6 years who have had a previous dengue infection and who will be exposed in a region with significant dengue transmission (this is not the case in Europe).
- For details, see ECTM Statement.
In case of fever:
- Ensure adequate hydration and apply paracetamol products.
- 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.
