The West Nile fever season, as expected, is currently showing a peak with the number of cases reported and newly affected areas increasing.
Over the previous week the number of West Nile fever cases has continued to grow: 28 new cases have been reported in EU, compared to 26 in the previous week report. Italy started to report during the past week non-neuroinvasive cases (11) detected since the beginning of the transmission season. There are newly affected areas in Italy and Romania, four newly affected provinces in Italy (Bologna, Mantova, Reggio nell’Emilia, Verona) and two newly affected counties in Romania (Constanta and Tulcea). The case detected in Austria has been withdrawn, as additional laboratory tests found no West Nile virus infection.
As of 5 September 2013, 106 human cases of West Nile fever have been reported in the EU and 289 cases in neighbouring countries since the beginning of the 2013 transmission season.
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.
