EHD can only be transmitted by a vector, meaning it cannot be transmitted from animal to animal, but only through the initial bite by a vector. Ordinarily, EHD outbreaks reoccur within an area primarily during seasonal dry spells. Outbreaks typically result in large die-offs, and smaller and more isolated outbreaks can be common. [9]
Epizootic hemorrhagic disease virus must be transmitted via bites from Culicoides gnats (C. verripennis) and cannot be transmitted directly from deer to deer. EHDV manifests itself as epizootic hemorrhagic disease (EHD), which has similar symptoms to adenovirus hemorrhagic disease (AHD), “bluetongue” disease, and malignant catarrhal fever.
Many orbiviruses are transmitted by ticks or haematophagus insect vectors (Culicoides, mosquitoes and sand flies) and have a wide host range that includes cattle, goats and sheep, wild ruminants, equids, camelids, marsupials, sloths, bats, birds, large canine and feline carnivores, and humans.

BTV can also be transmitted from mother to fetus. The outcome is abortion or stillbirth if fetal infection occurs early in gestation and survival if infection occurs late. However infection at an intermediate stage, before the fetal immune system is fully developed, may result in a chronic infection that lingers until the first months after ...
