Rift Valley Fever infects both livestock and humans. Rift Valley Fever is most commonly found in regions of eastern and southern Africa. It also exists in Madagascar and sub-Saharan Africa. It is primarily spread from infected mosquitoes, who then infect animals. Generally they infect domestic animals, such as buffalo, cattle, sheep, camels and goats. Once the livestock are infected, other mosquitoes can spread the disease. It is also possible that the infection can be spread from other biting insects. .
Humans can get Rift Valley Fever in numerous ways. Humans can be infected from the mosquitoes or the bodily fluids of the infected animal. Contact such as slaughtering the infected animal can occur also. Symptoms include influenza like illness, fever, liver abnormalities, muscle and back pain and vomiting. In the early stages of Rift Valley Fever, these symptoms are some times mistaken for meningitis. This fever may also perceive itself to be hemorrhagic fever. .
In diagnosing Rift Valley Fever, tests have demonstrated the presence of antibodies to the disease. Studies in animals have given antiviral drugs for the use of humans. Herdsman and animal workers in areas where Rift Valley Fever is present are at a greater risk of being infected. The risk of transmission can be reduced by, wearing gloves, insect repellent, the use of protective clothes, and avoiding outdoor activity during peak biting times. Surveillance is important to form effective measures for reducing the number of infections. .
