ECDC’s West Nile fever maps
The weekly West Nile fever report comprises maps of the present geographic distribution of reported autochthonous human cases in the EU and neighbouring countries, a situation update and a table presenting cases by country and area.
All information is provided in order to inform the competent authorities responsible for blood safety in areas with ongoing transmission of West Nile virus to humans in order to support the implementation of blood safety legislation.
According to EU blood safety legislation
, EU Member States must initiate control measures to ensure blood safety in the event of cases of West Nile fever. A major challenge to the implementation of this regulation has been the timely collection of accurate information about affected areas.
