Tel Aviv Resident Diagnosed With First West Nile Virus Case in Israel Summer 2026

The Israeli Ministry of Health and Ministry of Environmental Protection announced the first confirmed case of West Nile virus infection in the summer of 2026, involving a resident of Tel Aviv. Professor Sigal Sadetzki, head of the Public Health Division at the Ministry of Health, explained that West Nile virus is transmitted to humans through mosquito bites from mosquitoes that feed on infected birds. While most cases are mild or asymptomatic, severe symptoms such as encephalitis or meningitis can occur in rare instances.

Dr. Shay Reicher, director of the Pest and Rodent Control Division at the Ministry of Environmental Protection, stated that continuous monitoring of mosquito populations is conducted year-round, with increased focus during the mosquito season from June to November. Despite extensive surveillance involving thousands of mosquito larvae inspections and hundreds of adult mosquito captures tested in health laboratories, no infected mosquitoes had been detected so far this season.

The summer conditions of standing water and warm, humid weather increase mosquito breeding risks. Local authorities are responsible for removing public health nuisances related to pests, while the public is urged to eliminate standing water sources such as buckets, plant saucers, old tires, gutters, ornamental pools, and barrels. Protective measures include using mosquito repellents, installing window screens, wearing long light-colored clothing during dusk, and using fans to deter mosquitoes. Residents are encouraged to report mosquito nuisances or standing water in public areas to their local municipality via hotline 106.
