Which organism vector transmits African Horse Sickness?

The main idea is that African Horse Sickness is transmitted by tiny biting midges of the genus Culicoides. These midges become infected when they feed on an infected horse, then, after the virus replicates inside them, they transmit it to another horse during a subsequent bite. This Culicoides-based transmission cycle is what defines how the disease spreads in horses. Other mosquito genera like Aedes, Anopheles, and Culex are vectors for other pathogens (such as malaria, dengue, or West Nile), but they are not the usual transmitters of African Horse Sickness. Culicoides imicola, in particular, is a well-known vector in Africa and nearby regions, and environmental conditions that favor Culicoides activity help drive outbreaks.
