Travel-associated chikungunya cases: place of infection for cases imported into the EU/EEA
Chikungunya is an Aedes-borne disease, widely distributed across tropical and sub-tropical regions. Chikungunya is not endemic in mainland Europe and the vast majority of cases are travellers infected outside of the mainland European Union/European Economic Area (EU/EEA). Chikungunya is a notifiable disease at EU level and surveillance data is collected by ECDC through The European Surveillance System (TESSy).
With the aim of informing public health authorities and EU/EEA citizens of the risk related to chikungunya, ECDC has produced maps and the table below, displaying the places where reported travel-associated chikungunya cases were likely to have been infected. The report is based exclusively on the places of infection reported by EU/EEA countries to ECDC, using the most recently validated data available.
Locations outside mainland EU/EEA were included for which there was at least one confirmed chikungunya case (as per the EU case definition), where these locations were either reported as the place of infection in two different years during the past five years, or by two separate reporting countries. Cases reported with the place of infection in EU Overseas Countries and Territories (OCTs), or outermost regions were classified as travel-associated.
