West Nile Virus Detected in Mosquitoes in Northern and Central Israel

Mosquitoes carrying the West Nile virus have been identified in several areas of northern and central Israel, according to analyses confirmed by the Ministry of Health. Following this discovery, the Ministry of Environmental Protection has urged local authorities to enhance measures against mosquito proliferation, as reported by Kan. The infected insects were found during routine surveillance operations across the country, confirming the circulation of the virus. West Nile fever, transmitted to humans through the bite of mosquitoes that have fed on infected birds, is typically asymptomatic or causes mild symptoms like fever, headaches, fatigue, and muscle pain. However, in rare instances, it can lead to severe neurological complications, particularly affecting the elderly and immunocompromised individuals. Authorities have instructed municipalities and regional councils to intensify mosquito control efforts, locate breeding sites, and conduct spraying operations if necessary. Residents are also advised to eliminate standing water in gardens and outdoor spaces, which serves as a breeding ground for mosquitoes. Health officials recommend using repellents, installing mosquito nets, and wearing protective clothing, especially at dusk when mosquitoes are most active. The virus typically circulates in Israel from summer through early autumn, and prevention of bites and elimination of stagnant water remain the primary protective measures.
