Rift Valley fever is a viral disease that primarily affects animals (mainly cattle, sheep and goats) but can also be transmitted to humans. Camelids are also an important reservoir. The disease is caused by the Rift Valley fever virus (RVFV), which belongs to the genus Phlebovirus (family Phenuiviridae) and is mainly transmitted by mosquitoes of the genera Aedes and Culex. It is most common in Africa, but cases have also been reported in the Arabian Peninsula.
