• Rift Valley Fever is a disease that is spread to sheep, cattle and goats by mosquitos and it causes abortion and death of the animals.  
• Humans become infected from handling sick animals, carcasses or meat, or less often from mosquito bites. 
• The disease does not spread from person to person.
• Outbreaks of the disease have only occurred in Africa and Arabia and usually occur during periods of increased rain which increase the number of mosquitoes.
