The vast majority of vector-borne diseases are found in tropical areas of the world. Malaria, Dengue Fever, Yellow Fever, Onchocerciasis, and Filariasis cause human suffering and death throughout the world.

Although Imperial County has a more temperate climate, vector-borne diseases exist that can cause serious health problems. These diseases include Plague, Encephalitis, Lyme Disease, Hantavirus, and West Nile Virus. Monitoring and reacting to the presence of these diseases is vital to the protection of the health and well-being of our community.

The Imperial County Vector Control Program has been active in surveillance and control activities since 1992. The Department provides service to the unincorporated areas of Imperial County and the cities of El Centro, Brawley, Calexico, Holtville, Imperial, Calipatria, and Westmorland. Service calls are made concerning bees and mosquitoes. Informational pamphlets are also available for other types of pests.
