70-Year-Old Man Dies From West Nile Virus as Infected Mosquitoes Spread in Central Israel

A 70-year-old man in Israel has died from complications related to West Nile virus after developing symptoms in mid-July and being hospitalized. Since the beginning of 2026, ten cases of the disease have been diagnosed in Israel, with three patients currently hospitalized in stable condition. Epidemiological investigations are ongoing to determine the source of exposure.

For the first time this season, mosquitoes carrying the virus have been trapped in central Israel, including in Tel Aviv, Tayibe, Tira, Kalansawa, and the Lev HaSharon Regional Council. Previously, infected mosquitoes had only been found in southern Israel. In response, the Ministry of Environmental Protection has instructed local authorities in these areas to immediately intensify mosquito control, monitoring, and public awareness efforts.

West Nile virus is transmitted to humans through mosquito bites from mosquitoes that feed on infected birds. The risk of severe illness, such as encephalitis or meningitis, is higher among people aged 60 and older and those with underlying health conditions. Prof. Sigal Sadetzki, head of the Public Health Division at the Ministry of Health, emphasized the importance of preventive measures, noting that most cases are mild or asymptomatic but severe symptoms can occur.

Dr. Shay Reicher, head of the Pest and Pest Control Division at the Ministry of Environmental Protection, highlighted the role of the public in reducing mosquito breeding sites. Authorities urge residents to eliminate standing water sources, use approved mosquito repellents containing DEET, wear long light-colored clothing during peak mosquito activity, install window screens, and report mosquito nuisances or standing water to local municipal hotlines.

The Ministry of Health and Environmental Protection continue to monitor the situation closely as the mosquito season is expected to last until the end of November, with increased risk due to warm and humid weather conditions.
