Rift valley fever (RVF) is a vector-borne, zoonotic disease caused by Rift Valley fever virus (RVFV). RVFV is a negative-sense, single-stranded RNA virus of the family Bunyaviridae
within the genus Phlebovirus. RVF is endemic to sub-Saharan African countries and is characterized by high rates of abortions and neonatal mortality, primarily affecting humans, sheep, goats, and cattle. Young animals are most susceptible to infection with RVRV.
Transmission
RVF is transmitted through mosquitoes, stable flies, and other biting insects. It is also transmitted through close contact with blood and tissues of infected animals.
Incubation period
The incubation period from exposure to clinical signs ranges from 1 to 6 days.
