West Nile Virus Confirmed in Mosquitoes Across Israel, US Regions

Multiple regions including Israel, Niagara Region in Canada, Vigo County in Indiana, and Norfolk, Virginia, have detected mosquitoes carrying the West Nile Virus in 2025, prompting public health alerts and calls for preventive actions. In Israel, the Environmental Protection and Health Ministries confirmed infected mosquitoes in Eilat and reported two human cases in central Israel this year, urging intensified pest control and public cooperation to reduce mosquito populations. Niagara Region reported its first West Nile Virus-positive mosquitoes in Welland, advising residents to use protective clothing, repellents, and eliminate standing water, though no human cases have been identified there. Vigo County health authorities confirmed positive mosquito samples and provided extensive guidance on removing water sources to prevent mosquito breeding. In Norfolk, a mosquito tested positive for West Nile Virus, leading to mosquito control efforts and public warnings about symptoms and protective measures. Across all affected areas, officials emphasize that most infected individuals do not show symptoms, but vulnerable populations such as the elderly face higher risks of severe neurological complications.
