Since 2025, EU/EEA countries have seen a rise in dengue cases among travellers returning from the Maldives, though without increased severity. In 2026 so far, at least 46 imported cases have been reported across four countries, continuing a trend that intensified in late 2025. This mirrors a significant surge in dengue cases within the Maldives itself, with 631 cases reported in January 2026 compared to 72 in January 2025.
Prevention: Optimal mosquito protection 24/7, also against other mosquito-borne disease.
Vaccination: The Swiss Expert Committee for Travel Medicine (ECTM) recommends Qdenga® vaccination only for travelers over 6 years who have previously had a dengue infection, see ECTM statement.
In case of fever:
- 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.
