Local transmission of dengue virus in mainland EU/EEA, 2010–2024

Dengue is an Aedes-borne disease widely distributed in tropical and subtropical regions. Globally, the virus is predominantly transmitted by the Ae. aegypti and Ae. albopictus mosquitoes. Aedes albopictus is established in a large part of Europe. Aedes aegypti is established notably in Cyprus, around the Black Sea and in the outermost region (OR) of Madeira. 

Dengue is not endemic in mainland EU/EEA and the vast majority of the cases are travellers infected outside of mainland EU/EEA. See the risk assessment for mainland EU/EEA.

The table and map below illustrate the dengue situation in mainland EU/EEA, excluding the EU ORs. Historically, dengue has been endemic in the French ORs (i.e. French Guiana, Guadeloupe, Réunion, Martinique, Mayotte and Saint-Martin). Additionally, Madeira, an autonomous region of Portugal, experienced a major dengue outbreak in 2012. For the other ORs (the Azores, the Canary Islands), no dengue cases were reported.
