An alert has been issued for the West Nile virus in 41 towns across Spain, primarily in the Andalusian region. This virus, transmitted by mosquitoes, can cause severe inflammation of the brain and spinal cord, potentially leading to fatal outcomes. While most infected individuals remain asymptomatic, about 20% may experience fever, rash, and muscle aches.
Local authorities in Andalusia, particularly the Directorate-General for Public Health and Pharmaceutical Regulation, have placed several municipalities on alert after detecting the virus in mosquitoes. Benalup-Casas Viejas is one such area, with the alert set to last until October 5, unless new cases arise.
The Regional Ministry of Health has identified 25 towns in Cadiz at medium risk and 16 towns at high risk, necessitating intensified surveillance and public awareness campaigns. Measures include monitoring mosquitoes, animals, and humans, and promoting protective actions in schools and community centers.
Residents and tourists are advised to use mosquito repellents, wear light-colored clothing, and avoid going out at peak mosquito activity times, such as dawn and dusk. Home defenses should be strengthened with nets, insecticides, and by eliminating standing water to prevent mosquito breeding.
The Andalusian Regional Government’s risk map indicates that Cádiz is one of the provinces most affected by the virus, prompting significant preventive actions to curb its spread.
