Autochthonous vectorial transmission of dengue virus in mainland EU/EEA, 2010-present

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 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. When the environmental conditions are favourable, in areas where the competent vectors are established, viraemic travel-related cases may generate a local transmission of the virus, as demonstrated by the sporadic events of dengue virus transmission since 2010.
