West Nile virus cases detected in horses in Greece

Veterinary authorities in Greece confirmed five cases of West Nile virus among horses located on the same premises. The animals tested positive between September 9 and September 18, 2026, after exhibiting symptoms such as fever and walking difficulties. Officials stated that the animals remain alive and their symptoms have significantly waned, with no new cases identified since the initial report. Authorities have determined that no movement restrictions are necessary at this time.

Health experts emphasize that the West Nile virus is not transmitted directly from horses to humans or between animals. The virus is primarily spread to both humans and horses through the bites of infected mosquitoes, which carry the pathogen after feeding on infected birds. The World Health Organization notes that this is the standard cycle of transmission for the virus. While health authorities have issued general warnings for citizens to take precautions against mosquito bites, they maintain that the situation is currently under control. The department will continue to monitor the region to ensure animal health and prevent any further spread of the disease.
