Did you know? – West Nile Virus can infect humans, birds, horses, and other mammals. Birds are the natural reservoir for the virus,and mosquitoes transmit it between these hosts.

Health System on Alert

The SES Directorate has instructed the management of all eight health areas in the region to maintain a state of vigilance for any suspected cases with compatible symptoms. This proactive approach aims to increase diagnostic capabilities, even though approximately 80% of human infections with west Nile Virus are asymptomatic.

Last year, the region recorded 27 positive cases of West Nile Virus and two fatalities. The disease is typically transmitted through the bite of an infected mosquito. Extremadura and Andalusia are currently considered the most at-risk areas in the country, according to the Ministry of Health.

Pro tip: – Eliminate standing water around your home weekly. Mosquitoes can breed in as little as half an inch of water, so regularly check flower pots, gutters, and other containers.

SES Issues Prevention Guidelines

The SES is urging residents to take preventive measures against mosquito bites. Key recommendations include:

• Water Management: Maintain swimming pools, ponds, and rafts in good condition. Empty and remove standing water from items like plant saucers, jugs, buckets, toys, pet dishes, and tires.
• Outdoor Water Containment: Cover outdoor water containers and keep roof gutters and courtyard drains clean to prevent mosquito breeding.
• Personal Protection: wear light-colored clothing that covers as much of the body as possible, including long sleeves, long pants, and closed footwear.
• Repellents and Barriers: Avoid scented soaps, perfumes, and hairsprays, which can attract mosquitoes. Use authorized repellents in lotions, sprays, or bracelets. Installing mosquito nets on doors and windows is also recommended.
