Common methods of contact include butchering animals, assisting in animal births and disposing of deal animals. Other known methods to acquire RVF are through mosquito bite (Aedes Species), drinking unpasteurized milk or eating poorly cooked/raw infected animal meat.

Kenya, Somalia, Tanzania, Saudi Arabia and Yemen have all suffered epidemics.
