According to the European Centre for Disease Prevention and Control (ECDC), local health authorities on Madeira reported two locally acquired cases of dengue on 18 February 2025.
Dengue is an infection mostly found in tropical and sub-tropical climates worldwide. It is spread by Aedes mosquito bites and can cause a severe flu-like illness.
All travellers to affected regions are potentially at risk of dengue fever and should be aware of this infection.
Aedes mosquitoes are particularly persistent and aggressive. They bite between dawn and dusk.
A new dengue vaccine Qdenga® has been licensed in the UK.
Treatment for dengue is supportive only.
