Hemorrhagic disease is an insect transmitted viral disease of wild ruminants. It is caused by two closely related orbiviruses, the bluetongue viruses (BTV) and the epizootic hemorrhagic disease viruses (EHDV). Disease caused by these two viruses is indistinguishable and is collectively referred to as hemorrhagic disease (HD). HD has been associated with significant mortality only in North American ungulate populations.
