Rift Valley Fever is a viral zoonotic disease transmitted by arthropods.1, 2, 3, 4 This viral disease mainly affects domestic animals but has the ability to affect living beings humans.1,3,4 The severity of the disease can range from mild to severe and can be potentially fatal.1 An epidemic in the animal population, also known as an epizootic, could lead to greater economic losses as the disease leads to the death of livestock and to spontaneous abortion among animals. pregnant animals .1, 2, 3, 4 A reduction in trade could also contribute to further economic losses.1, 2, 3, 4 The virus that causes Rift Valley fever belongs to the Bunyaviridae family and the Phlebovirus genus.1, 2 , 3, 4, 5 Rift Valley fever was first reported around 1910, but was not identified until a sheep farm in Kenya was investigated after an outbreak in 1931. 1, 2, 3, 5 The name common virus originates from the area where it was identified, the Rift Valley of Kenya.1 Most reported outbreaks of Rift Valley fever have occurred in sub-Saharan and northern Africa.1, 3, 4 The animal epidemic most notable Rift Valley fever occurred in Kenya from 1950 to 1951.3, 4 This epidemic resulted in the death of approximately 100,000 sheep.3, 4 An epidemic in Egypt caused the death of approximately 600 people and a significant number of animals in 1977.3, 4 In September 2000, the first cases of Rift Valley fever outside of Africa were confirmed in Saudi Arabia and later in Yemen.1, 2, 3, 4 Since the disease was confirmed outside of Africa , Rift Valley Fever has been identified as a priority disease that has the potential to emerge geographically.2Transmission of Rift Valley Fever to humans Transmission of the disease may be the result of certain dis... half of document ... ...t about 1%.1, 2, 3, 4 Transmission to humans occurs through direct or indirect contact with infected animals or their body fluids or infection through the bite of an infected mosquito.1, 2 , 3, 4 Rift Valley fever has been found to have a high colonization capacity which greatly increases its potential emerging risk in Western nations. 2 The virus itself can survive in a wide range of bioclimatic environments due to its of transmission.2 The introduction of Rift Valley fever into previously unaffected regions may be due to the potential movement of hosts and vectors through trade or migration.2 Mechanical transport of arthropod vectors is the most likely mechanism of disease dispersal .2 The potential geographic spread of Rift Valley fever is why the disease has been identified as a priority emerging disease.2
