West Nile Virus Detected in Ashdod Mosquitoes, Health Ministry Urges Caution

Mosquitoes infected with the West Nile virus have been discovered in Ashdod, Israel, according to the Ministry of Environmental Protection. The findings resulted from routine monitoring, the ministry reported on September 11, 2026. In response, the ministry has instructed all local authorities to enhance prevention, monitoring, and public awareness efforts to mitigate the virus's spread and safeguard residents' health.

The West Nile virus is transmitted to humans through the bites of mosquitoes that have fed on infected birds. While most human cases are asymptomatic or present mild, flu-like symptoms, some individuals, particularly the elderly and those with chronic conditions, may experience severe neurological complications.

The mosquito season, during which the virus is active, typically runs from June to November. During this period, authorities conduct regular insect trapping and laboratory testing. When infected mosquitoes are found, local councils and municipalities are directed to intensify efforts to eliminate mosquito breeding sites.

Public recommendations remain consistent: eliminate standing water sources in yards and on balconies, such as pot saucers, buckets, old tires, and gutters. Residents are also advised to use insect repellent, install window screens, wear long sleeves in the evenings, and report mosquito swarms to city services by calling 106.

The Ministry of Environmental Protection emphasized that while local authorities are responsible for treating public areas, active community participation is crucial for reducing mosquito populations. Monitoring continues, and the public will be updated on further findings. Residents of Ashdod and other communities are urged to maintain these precautions until the end of the mosquito season.
