West Nile fever

2018 West Nile fever season: cases so far exceed the total number in previous five years

Compared to previous years, West Nile fever case numbers have increased threefold. For comparison, within only one week, in the end of August, 300 human cases were notified in the EU – this is more than the total number of annual cases reported in 2017 (207 cases) or 2016 (225),  and similar to the numbers for the last major season, in 2010 (393). 

It is likely that the virus will spread to more areas in the coming months, including areas where no human locally acquired cases have been reported previously, states ECDC risk assessment.

ECDC monitors the West Nile fever cases in Europe and issues weekly updates, each Friday, during the transmission season.   

Last updated: 12 October 2018

reported in 10 EU countries
