Article: 55/0805

As of 1 February 2021, the European Centre for Disease Prevention and Control (ECDC) reported that EU and EEA member states and EU-neighbouring countries had provided notification of 336 locally-acquired human cases of West Nile virus (WNV) infections in 2020, with 316 cases having a known place of infection. This total includes 38 deaths.

During this transmission season, the Netherlands reported their first detection of a WNV infection in a bird and subsequently the first detection of human cases of WNV infection. This corroborates the further expansion of WNV circulation in Europe. All other human infections in 2020 were reported in countries with known persistent transmission in previous years.
