Rift Valley fever
Rift Valley fever is a viral zoonosis causing fever. It is spread by the bite of infected mosquitoes, typically the Aedes or Culex genera. The disease is caused by the RVF virus, a member of the genus Phlebovirus. The disease was first reported among livestock in Kenya around 1915, but the virus was not isolated until 1931. RVF outbreaks occur across sub-Saharan Africa, with outbreaks occurring elsewhere infrequently, but sometimes severely. In Egypt in 1977-78, an estimated 200,000 people were infected and there were at least 594 deaths among hospitalized patients. In Kenya in 1998, the virus claimed the lives of over 400 Kenyans. In September 2000, an outbreak was confirmed in Saudi Arabia and Yemen. On 19 Oct 2011, a case of Rift Valley fever contracted in Zimbabwe was reported in a Caucasian female traveler who returned to France after a 26-day stay in Marondera, Mashonaland East Province during July and August, 2011 but later classified as 'not confirmed.'
