Rift Valley fever n. a viral disease of eastern and southern Africa, originally recognized in livestock and later found also to affect humans, caused by a phlebovirus (family Bunyaviridae; see bunyavirus n.), transmitted by mosquitoes, and characterized by severe disease with hepatitis, enteritis, and abortion in livestock and (usually) a milder acute febrile illness in humans.
