定义

  • Information Epizootic haemorrhagic disease (EHD) is a vector-borne infectious noncontagious viral disease of domestic and wild ruminants, primarily white-tailed deer (Odocoileus virginianus) and cattle. Sheep, goats and camelids might also be susceptible, but usually do not develop overt disease. EHD virus (EHDV) is transmitted between ruminant hosts by species of Culicoides biting midges, thus EHD infections are strongly seasonal. White-tailed deer is the most severely affected species, with the peracute form having a high mortality rate. (en)
