The large outbreak of human West Nile virus infection in Greece in 2010 also marked the first outbreak of this mosquito-borne disease in this country. In 2011 and 2012, further cases were observed, both in previously affected and non-affected areas.

Within the context of the West Nile virus outbreaks, an ECDC mission was conducted at the end of the transmission season to support the Greek authorities regarding further response and prevention activities on West Nile virus infections.
