The clinical disease is seen often in sheep, antelope, bighorn sheep and some wild animals. No clinical disease is seen in cattle, but the recent outbreak in Europe with BTV 8 was more manifested in cattle. The disease was reported for the first time in South Africa by Hutcheon in 1881 and it was described as â epizootic catarrhâ ?. In 1905, Spreull renamed the disease as bluetongue based on clinical signs.Thesis
