African Horse Sickness is a virus. It affects all species of Equidae. It is classified as an Orbivirus of the Reoviridae family of which there are 9 serotypes. All serotypes (1-9) are distributed throughout South Africa. The virus is transmitted from animal to animal when Culicoides midge feeds on an infected animal, acquires the virus, and then feeds on a susceptible animal, transmitting the virus to the susceptible animal. The virus over-winters during periods of low midge activity (winter) in resistant Equines such as zebra.
