A Tel Aviv man has been diagnosed with the mosquito-borne West Nile virus, marking the first confirmed case of the disease in Israel during the 2026 summer season, health and environmental authorities said on Thursday.

The Health Ministry and Environmental Protection Ministry said that, despite the confirmed case, routine monitoring has so far not detected any mosquitoes carrying the virus.

West Nile virus is transmitted to human beings through the bites of mosquitoes that have fed on infected birds, Prof. Sigal Sadetzki, head of the Health Ministry’s Public Health Services Division, said in the statement.
