Israel has seasonal mosquito activity from April through November, with peak risk during the summer months. The Jordan Valley, the Hula Valley, coastal plain, and the Negev oases carry the most mosquito exposure. Urban areas including Tel Aviv have nuisance mosquito populations near water sources.
West Nile virus is the primary mosquito-borne disease concern, with periodic outbreaks particularly in the central and northern regions. Israel has no malaria transmission. The well-developed health surveillance system enables rapid outbreak detection.
Culex pipiens is the dominant vector for West Nile virus. Aedes albopictus has been detected in recent years. The Mediterranean climate and effective public health infrastructure keep mosquito-borne disease risk relatively low.
