West Nile virus is present yearly in Israel, with the risk highest from June through November, especially in the central region, due to high humidity and favorable conditions for mosquito breeding.
Israel reported 23 cases in 2020, 34 in 2021, 25 in 2022, and 53 in 2023.
West Nile virus is transmitted through the bite of an infected mosquito.
However, approximately 20 percent of infected people develop febrile illness characterized by symptoms of fever, headache, body aches, joint pains, vomiting, diarrhea, and rash.
Symptoms typically appear 2-6 days after being bitten but can develop up to 14 days after exposure.
