Rift Valley Fever is a '''[[Viruses |viral]] disease''' caused by a [[:Category:Bunyaviridae|bunyavirus]]. It infects cattle, sheep, goats, camels and people.

Rift Valley Fever (RVF) is a viral zoonotic disease belonging to the family ''Bunyaviridae'' in the ''Phlebovirus'' genus, possessing a segmented negative sense RNA genome. The disease has an episodic occurrence remerging ever 5-25 years and is seasonal in its occurrence. The occurrence of non immune animal populations every 5-25years combined with the introduction of RVF (due to rainfall) accounts for the explosive cyclical nature of the disease. RVF primarily affects animals but can infect humans and has the capacity to cause severe disease in both.

 

RVF has a wide economic impact due to livestock loss and trade restrictions as well as public health implications. It is a notifiable disease.

RVF causes significant '''economic losses in Africa''', both directly through its clinical cases and also as an obstruction to the improvement of breeding stock due to the susceptibility of most imported livestock breeds into endemic areas.

 

This disease is '''notifiable''' to the World Organisation for Animal Health [http://www.oie.int/ (OIE)]
