− | AHS is a non-contagious arthropod-borne disease of equidae. The causal agent is an [[African Horse Sickness|orbivirus]] existing in nine serotypes. The occurrence of AHS is both cyclical and seasonal and dependent on the vector, usually [[Biting Flies#Ceratopogonidae|''Culicoides'']]. Equine encephalosis, caused by a related orbivirus, follows a similar distribution and epidemiology to African Horse Sickness and can present with similar signs. | + | [[Image:AHS 2 donkey.jpg|right|thumb|200px|<small><center>African horse sickness (Image courtesy of [http://drupal.thedonkeysanctuary.org.uk The Donkey Sanctuary])</center></small>]] |

| AHS is endemic in the sub-Saharan region and certain parts of South Africa, where severe epidemics occur in naïve horse populations (Lord ''et al.'', 2002; Coetzer & Guthrie, 2004). AHS occasionally occurs as outbreaks in North Africa, intermittently spreading to the Mediterranean area and the Middle East. | | AHS is endemic in the sub-Saharan region and certain parts of South Africa, where severe epidemics occur in naïve horse populations (Lord ''et al.'', 2002; Coetzer & Guthrie, 2004).
