West Nile virus cases surge in Greece, Italy and North Macedonia

West Nile virus Greece Italy North Macedonia travel warning

Health authorities report a sharp increase in West Nile virus infections across Southern Europe. Greece has recorded 42 cases as of 29 July 2026, with 35 in the Attica region, and four deaths among people aged 66‑91. The Greek public‑health agency warned that the season’s peak is expected from mid‑August to early September and urged protective measures against mosquito bites. Italy has confirmed 21 infections in 17 regions, while North Macedonia announced 13 confirmed cases, three of which are in critical condition.

The World Health Organization and Germany’s Auswärtiges Amt have issued travel advisories for Italy, Greece and other Mediterranean destinations, recommending repellents and clothing to avoid mosquito exposure. In Italy, entomological surveillance detected West Nile virus lineage 2 in Culex pipiens mosquitoes captured near Mosciano Sant’Angelo. Greek authorities have launched large‑scale ULV insecticide spraying in several Attica municipalities and Eastern Macedonia‑Thrace, with special permission from the health minister. The outbreak has prompted heightened public‑health monitoring and vector‑control actions throughout the affected regions.
