West Nile virus cases surge in Italy, Greece and Southern Europe

The European Centre for Disease Prevention and Control (ECDC) reported 81 locally acquired West Nile virus infections across the continent as of late July 2026. Italy accounts for the largest share with 46 confirmed cases in 20 regions, including major urban areas such as Milan and Rome. Greece follows with 21 cases, 14 of which were confirmed in a single week, and several patients have developed severe neuro‑invasive disease. Smaller clusters were reported in North Macedonia (5 cases), Romania (5 cases, two deaths), Spain (3 cases), France (1 case) and Germany (two travel‑related cases).

The World Health Organization (WHO) warned that the risk of severe disease remains low for most people, but highlighted that prolonged hot summers extend the mosquito season and increase exposure. Health authorities issued travel advisories for tourist hotspots on Spain’s Costa del Sol, including Fuengirola and Mijas, urging the use of repellents, protective clothing and removal of standing water. Similar protective recommendations were circulated in Italy, Greece and other affected areas.

Public health officials stress that no vaccine or specific antiviral treatment exists; prevention relies on personal measures and intensified mosquito surveillance. The outbreak underscores the broader impact of climate‑driven mosquito expansion throughout southern Europe.
