A mosquito-borne viral disease of cattle, sheep, goats and camels, first identified in Kenya's Rift Valley in the 1930s, that causes abortion storms in pregnant animals and high mortality in newborn lambs and calves, and that is also a serious zoonotic disease capable of causing hemorrhagic fever in humans. Outbreaks follow periods of unusually heavy rainfall that create the flooded breeding sites its mosquito vectors need, and major epidemics across East Africa, Egypt and the Arabian Peninsula have periodically devastated livestock herds and disrupted livestock export trade for years afterward.
