Mosquitoes are one of the most important vectors of diseases for humans and animals caused by bacteria, parasites and viruses, including malaria, dengue fever, Zika and RVF. Rift Valley Fever (RVF) is a zoonotic viral disease transmitted by various species of mosquito that infects animals and human alike. The disease is transmitted from the infected animals or through contact with their blood or tissues. The virus remains inside the drought-tolerant eggs in moist or semi-dry soil for many years. It is a disease without symptoms at first, yet it causes economic and health losses to animals and humans. Since there is no available vaccine for the animals and the absence of a licensed vaccine for humans, it is considered an epidemic disease. Its distribution extends from Africa to the Kingdom of Saudi Arabia and Yemen, and for fear of the disease spreading to other regions of Asia, efforts must be made to uncover risk factors and insect habitats to get health prevention and mosquito control.
