EODY detects first West Nile virus cases of 2025 in Greece
Four cases of infection were simultaneously identified in Attica over the past 48 hours, with the most likely areas of exposure being western Attica and Piraeus.
The cases involve patients over the age of 65 who developed symptoms of encephalitis in late June.
Since 2010, cases of West Nile virus have been reported almost every year in Greece.
The virus is primarily transmitted through the bite of infected mosquitoes.
Infected humans do not transmit the virus further to other mosquitoes or people through direct contact.
The majority of infected individuals either do not become ill at all or experience only mild symptoms.
However, a small percentage (less than 1%) develop severe illness affecting the nervous system, most commonly encephalitis or meningitis.
