ECDC is now publishing the West Nile fever maps for the 2015 transmission season. As of 5 June, no West Nile fever cases have been reported in EU and neighboring countries.

From 2015 the West Nile fever maps data will be displayed through a web-based tool allowing the user to interact with the data. The seasonal West Nile data is now integrated within the Surveillance Atlas of Infectious Diseases: an ECDC tool which gives online access to infectious disease surveillance data through a user-friendly interactive interface. The usual seasonal weekly maps and tables of the reported autochthonous human cases in Europe and the Mediterranean basin will now be presented in an interconnected webpage with selectable time and case indicators.

As done previously, the West Nile case data from Europe and the Mediterranean basin will be updated every Friday. The information, based on cases reported up to the Thursday of each week, will be summarized in a weekly situation update, in maps showing the present geographical distribution of the reported autochthonous human cases the week and a table on the number of cases according to countries and areas. However, data are now connected so that the users will be able to access in the same view the location of an area and its epidemiological situation. It will be possible to select this area either from the map or from the table. The user will also be able to select from a set of indicators (recent cases only or both recent and historical cases) and between 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.
