title: The 1970 yellow fever epidemic in Okwoga District, Benue Plateau State, Nigeria. I. Epidemiological observations.
abstract: A focal epidemic of yellow fever occurred in late 1970 in southern Benue Plateau State, Nigeria, 1 year after a much larger outbreak in northern Nigeria. Like its predecessor, the 1970 epidemic was associated with virus transmission by wild-breeding Stegomyia mosquitos. Epidemiological data on the outbreak are reported in this paper.
