Rift Valley fever (RVF) is an anthropozoonosis caused by Rift Valley fever virus (RVFV). RVFV belongs to the Phlebovirus genus in the family Bunyaviridae, which is circulating among ruminants. Human infection with RVFV is generally asymptomatic, however, minority of patients develop severe RVF diseases like encephalitis or hemorrhagic complications, with a fatality rate up to 50%. RVF mostly distributed in eastern and southern Africa, including Kenya, Zimbabwe, Zambia, Nambia and Somalia (LaBeaud et al., 2011; Shivanna et al., 2016). Infected cases were also reported in Egypt, Saudi Arabia and Yemen (Ikegami and Makino, 2011). Large outbreaks of RVF occurred in Kenya, Madagascar and South Africa with rapid spread (Jean Jose Nepomichene et al., 2015). In recent years, the import and export trade of animals increased remarkably along with the development of transportation and tourism, which raise the risk of RVFV transmission. The epidemic in Niger caused wide spread...
