Frequently Asked Questions (FAQs)

I undestand that the disease is transmitted by midges and can "over-winter" in animals such as zebras but what is the orginal pathogen of the disease?

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 feedson 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.
