During the 2023 West Nile virus transmission season, and as of 4 January 2024, 709 locally acquired human cases of West Nile virus infection, including 67 deaths, were reported by nine European Union countries.
Japanese encephalitis virus is present in Asia and Oceania, from Japan to India, Pakistan and Australia. Outbreaks are erratic and spatially and temporally limited phenomena, occurring quite unpredictably. The virus is a leading cause of viral encephalitis in Asia, with 30 000 to 50 000 cases reported annually.
West Nile virus is a mosquito-borne flavivirus that is maintained in an enzootic cycle between mosquitoes and birds. Humans and horses are incidental dead-end hosts.
Sindbis virus is widely and continuously found in insects (the main vectors are Culex and Culiseta mosquitoes) and vertebrates in Eurasia, Africa, and Oceania. ECDC factsheet for health professionals
To assess the level of preparedness of EU/EEA Member States to respond to zoonotic avian flu outbreaks, ECDC has carried out two surveys - one assessing the laboratory capacity for molecular diagnosis and characterisation of zoonotic influenza viruses, and the other focusing on measures applied to protect exposed people during outbreaks of highly pathogenic avian influenza.
Campylobacteriosis and salmonellosis were the most frequently reported zoonotic diseases in humans in the EU in 2022. For West Nile virus, an increase of the number of infections was observed.
In a technical report published today, ECDC, proposes a targeted testing approach in areas with ongoing avian influenza outbreaks in poultry and detections in wild birds and other animals, focusing on severe respiratory or unexplained neurological disease.
