Surveillance and updates for chikungunya virus disease
Chikungunya worldwide overview
Chikungunya contracted during travel: likely places of infection reported by travellers to the EU/EEA
This page displays the places where reported travel-associated chikungunya cases are likely to have been infected.
Local transmission of chikungunya virus in mainland EU/EEA, 2007–present
Chikungunya is not endemic in the EU/EEA and the 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 chikungunya virus transmission since 2007.
Reports
The likelihood of introduction of the virus to continental EU countries through viraemic travellers returning from endemic subtropical and tropical countries is high.
Since 2007, both France and Italy reported autochthonous transmission of chikungunya virus. The report of a cluster of autochthonous chikungunya cases in an area of Europe where Aedes albopictus is established is not unexpected during summer and autumn months when environmental conditions are favourable for increased mosquito abundance and activity.
