Greek health authorities warn that the most challenging period for West Nile virus is yet to come. The National Organization of Public Health (EODY) reports a current outbreak, potentially linked to the exceptionally warm winter of 2025-2026 in Attica, which was the second warmest in 150 years. This unusually mild winter likely contributed to the current epidemiological situation by favoring mosquito reproduction. While no specific timeline for the peak was given, officials anticipate an increase in cases. Residents are urged to take preventative measures against mosquito bites. Further monitoring and public health guidance are expected as the situation evolves.
