Local authorities in Greece have implemented mosquito control measures to prevent the spread of the West Nile virus.

In the community of Karitsa, the Municipality of Dion-Olympus scheduled emergency night-time spraying operations for September 1, 2026. These operations, targeting drains and stagnant water, were designed to minimize public exposure and protect residents, pets, and livestock.

In the Municipality of Thebes, officials have intensified their response by scaling up spraying and sampling operations across both rural and urban environments. This intensification follows a coordination meeting and includes targeting streams, canals, and flooded areas in communities such as Mouriki, Ypato, Platanaki, Eleona, and Neochoraki. These emergency interventions supplement a weekly program that has been active since March 2026, utilizing new mapping to identify mosquito breeding sites.
