Focus of infection

For the theory of local infections causing other diseases in the body, see focal infection theory

A focus of infection is a place containing whatever epidemiological factors are needed for transmission of an infection. Any focus of infection will have a source of infection, and other common traits of such a place include a human community, a vector population, and environmental characteristics adequate for spreading infection.[1]
