West Nile Virus Mosquitoes Detected in Southern Israel as Six Cases Confirmed in 2026

For the first time in 2026, mosquitoes carrying the West Nile virus have been detected in Israel, specifically in the Tamar Regional Council in the south. Since the beginning of the year, six human cases of the disease have been diagnosed across the country. The Ministry of Health and the Ministry of Environmental Protection have urged local authorities to intensify monitoring, prevention, and mosquito control efforts to curb the spread of infected mosquitoes.

The infected mosquitoes were identified through routine surveillance conducted by the two ministries, which operate year-round with increased focus during summer months. Following the discovery, the Ministry of Environmental Protection instructed the Tamar Regional Council and other local authorities nationwide to expand their efforts in mosquito control and public awareness to protect public health. No additional infected mosquito hotspots have been found so far.

West Nile fever is transmitted to humans through mosquito bites from mosquitoes that feed on infected birds. Professor Sigal Sadetzki, head of the Public Health Division at the Ministry of Health, explained that most cases are mild or asymptomatic, but rare severe complications such as encephalitis or meningitis can occur.

Dr. Shay Reicher, director of the Pest and Mosquito Control Department at the Ministry of Environmental Protection, highlighted that the detection demonstrates the effectiveness of the national monitoring system, which enables timely identification of risk areas and rapid response. He emphasized the public’s role in reducing mosquito breeding by eliminating standing water and reporting mosquito nuisances to local authorities.

The ministries recommend preventive measures including draining standing water from containers like flower pot trays and barrels, using mosquito repellents, installing window screens, wearing long light-colored clothing during evening and night hours, and using fans to deter mosquitoes. The public is also encouraged to report standing water and mosquito problems to municipal hotlines to facilitate swift action. Surveillance will continue nationwide with updates provided as necessary.
