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

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 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.

DENV-1 and DENV-2: Dengue virus serotype 1 and 2, respectively.

The table combines information published in official reports and in the scientific literature plus information that was provided by the public health institutes and/or the ministries of health in the affected Member States.
