Autochthonous transmission of dengue virus in EU/EEA, 2010-2019

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. While Ae. aegypti is so far not established in continental EU, Ae. albopictus is established in the southern and central parts of the EU and is spreading. 

Dengue is not endemic in the EU/EEA and the vast majority of the cases are travellers infected outside of the EU/EEA.  When the environmental conditions are favourable, in areas where Ae. albopictus is 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.
