West Nile fever in Europe: ECDC starts monitoring for the 2016 transmission season

​This week ECDC has started the seasonal monitoring of West Nile fever and the first West Nile fever maps for the 2016 transmission season are published today.

As of 2 June, no West Nile fever cases have been reported in EU and neighboring countries.

The West Nile case data from Europe and the Mediterranean basin are updated every Friday during the season, based on cases reported up to the Thursday of each week.

The weekly update contains:

  • a weekly situation update,
  • maps showing the present geographical distribution of the reported autochthonous human cases for the week, and
  • a table on the number of cases by country and area.

Since 2015, the West Nile fever maps are displayed through the Surveillance Atlas of Infectious Diseases: ECDC web-based tool allowing the user to interact with the data:

  • The users can get, in the same view, the location of an area and its epidemiological situation and have the possibility to select this area either from the map or from the table.
  • The users are also able to display the map with cases occurring in the current season only or combined with historical cases* and at different periods of time during the current season.

The objective of the West Nile maps project is to inform the competent authorities responsible for blood safety, of areas with ongoing transmission of West Nile virus to humans, in order to support the implementation of blood safety legislation. According to the EU blood safety legislation, the EU Member States have to initiate control measures to ensure blood safety in the event of cases/outbreaks of West Nile fever, a major challenge for the implementation of this regulation being the timely collection of accurate information about affected areas.
