Epizootic hemorrhagic disease (EHD) is a vector-borne viral disease of the genus Orbivirus in the familyReoviridae. EHD is an infectious, non-contagious disease affecting wild and domestic ruminants that utilizes biting insects of the Culicoides spp. as its mode of transmission. In addition to mode of transmission, EHD virus (EHDV) shares many similarities to the Bluetongue virus (BTV). Considerable extrapolation from BTV research has been applied to EHDV due to these similarities; however, there is no cross-protection between the viruses. Both viruses have a double-stranded RNA genome of 10 segments that code for 11 proteins. One of these proteins is the outer capsid protein, VP2, which determines the virus serotype. Currently, there are seven EHD serotypes, three of which are found in North America (EHDV-1, -2, and -6). The North American serotype EHDV-6 (Indiana) is a reassortment of EHDV-2 (Alberta) and EHDV-6 (Australia), which can cause bluetongue-like clinical disease in cattle.
Historically, clinical disease has only been apparent in wild ruminants, especially white-tailed deer (Odocoileus virginianus). Domestic ruminants were thought to be reservoirs, and clinical disease a rare occurrence. In 2008, following several clinical outbreaks in cattle, the World Organization for Animal Health (OIE) added EHD to its emerging diseases list. The emergence of cattle-virulent strains, as well as, the established cervid-virulent strains has drawn attention to the vast potential for production losses in both the cattle and the deer industries. A thorough understanding of the virus in wild and domestic ruminant populations and measures to control the vector of transmission is essential to minimizing production losses caused by EHD. One (1) Continuing Education (CE) credit is offered for this seminar.
