Which virus family and forms are associated with African Horse Sickness?

African Horse Sickness is caused by a virus in the Reoviridae family, specifically an orbivirus known as African horse sickness virus. The disease shows several clinical forms depending on which tissues are most affected, and these forms are key to recognizing and understanding the illness. The pulmonary (or peracute) form involves severe respiratory distress with edema in the lungs and mucous membranes, and it tends to be rapidly fatal. The systemic forms refer to involvement beyond the lungs, notably the cardiac (congestive) form, with edema of the head and neck and other systemic signs, and can be severe as well. This combination of a Reoviridae orbivirus and the two distinct form types—pulmonary and systemic—fits the classic presentation of African Horse Sickness.
