The ECDC has recently issued a warning of an unusually high occurrence of West Nile Fever in the summer of 2018 in several countries in Central and South Europe.

By 9 August, 335 confirmed or probable local cases of West Nile Fever had been detected in the following countries: Italy 123, Serbia 102, Greece 59, Romania 23, Hungary 23 France 3, and Kosovo 2 (see Figure 1).

In comparison, during the same summer period in the years 2014-2017 only 5-45 annual cases per year were reported. Furthermore, the West Nile Fever season in Europe started a few weeks earlier in 2018 than normally.

64 areas within the countries listed above are affected. This includes 13 areas that have not seen any West Nile Fever cases in the 2014-2017 period.
