ECDC publishes weekly West Nile fever maps, based on information provided by the health authorities across Europe, with the objective to inform the national competent authorities about WNV affected areas.

The report includes a map showing the geographical distribution of the reported human cases; as well as a situation update and a table on the number of cases according to countries and areas.

It is published on the ECDC website every Friday – the information is based on reported cases by Thursday.

The data encompasses EU Member States and the bordering countries, included in the WHO European region and/or bordering the Mediterranean Sea. It refers to autochthonous human cases of WNV infection only.
