Historically, Malaria was local in the Shasta Mosquito and Vector Control District, causing the initiation of organized mosquito control here in 1919. However, Malaria was eradicated in California in the 1950's as part of a coordinated nationwide governmental public health project.

It is vectored by Anopheles spp. mosquitoes from an infected human to a new susceptible human host. There are several plasmodia (single celled parasites) responsible for the illness, and the severity of the disease can be in­fluenced by the infective plasmodium.
