Abstract

Rift Valley fever (RVF) is one of the most serious Transboundary, infectious diseases. It is a mosquito-borne viral zoonotics disease, which causes periodic severe epidemics, principally characterized by high mortality rate of young animals and abortion in pregnant ruminants such as sheep, goats, and cattle following heavy rain falls in sub Saharan Africa. The disease is also transmitted to humans through mosquito bites or, handling of infected animal tissues, (Eisa et al., 1977, Lefevre, 1997). Rift Valley Fever virus (RVFV) of the family Bunyaviridae is the cause of RVF infection (Daubney et al., 1930). Since the first isolation of the virus in 1930s, there have been several epizootics outbreaks in tropic mainly in Africa including Sudan, which is one of the largest countries in Africa (Adam et al).
