“…A large number of EHDV mortality was reported in United States during summer and fall of 2012, including multiple species cattle (129 herds), captive white-tailed deer (65 herds), bison (8 herds), yak (6 herds) elk (1 herd) and sheep (1 flock). The average mortality withinherd morbidity was 7% in cattle and bison herds, and 46% in captive white-tailed deer herds and the average within-herd mortality in captive white-tailed deer herds was 42% [40]. However, the major observation can be found as high temperatures facilitate the transmission of EHD virus by C. sonorensis midges by decreasing the extrinsic incubation period of the virus.…”

The world livestock industry emerging by defeating all its limits and challenges in the course of mass production. Many pathogenic disease outbreaks restrict the scope for a better management practice rather to go for a better medication. Epizootic hemorrhagic disease virus (EHDV) can be considered as the major threat in the livestock industry causing severe loss in the production as well as revenue generation. Several EHDV outbreak reports have been recorded along with immense research to understand the molecular mechanism of viral replication along with the structure, while a better management practice can strongly expect to prevent the subsequent infection. Several important characters directly or indirectly influence the EHDV outbreaks in different locations. The continuous disease occurrence and its significant impact on the livestock industry impose the conception of the management practice to prevent further consequences of EHDV infection.

“…This is much fewer compared to the over 400 complete genomes available for BTV (http://btv.glue.cvr.ac.uk/#/home). Despite the recent EHDV-6 outbreaks in beef and dairy cattle in Israel (Golender et al, 2017) and Japan (Kamomae et al, 2018) during 2015, and the many EHDV-6 outbreaks observed in Mediterranean countries, there are currently only six complete genomes of EHDV-6 available in GenBank. Three of these sequences are from EHDV-6 isolates from the 1980s and 1990s (AUS1981/07, BAR1983/01, and M44/96), and the remaining three are from the USA (CC 304-06, 12-3437-8, OV208).…”

Epizootic hemorrhagic disease virus (EHDV) is a Culicoides-transmitted orbivirus that infects domestic and wild ruminants in many parts of the world. Of the eight proposed serotypes, only EHDV-1, 2 and 6 have been reported to be present in the Americas. Following the identification of a virulent EHD-6 reasssortant virus in the USA in 2007 (EHDV-6 Indiana), with outer coat protein segments derived from an Australian strain of EHDV and all remaining segments derived from a locally circulating EHDV-2 strain, questions have remained about the origin of the Australian parent strain and how it may have arrived in the USA. When EHDV-6 was identified in asymptomatic cattle imported into the Caribbean island of Trinidad in 2013, full genome sequencing was carried out to further characterise the virus. The EHDV-6 Trinidad was a reassortant virus, with 8 of its 10 segments, being derived from the same exotic Australian EHDV-6 strain as the VP2 and VP5 present in the EHDV-6 Indiana strain from the USA. Analyses of the two remaining segments revealed that segment 8 showed the highest nucleotide identity (90.4%) with a USA New Jersey strain of EHDV-1, whereas segment 4 had the highest nucleotide identity (96.5%) with an Australian EHDV-2 strain. This data strongly suggests that the Trinidad EHDV-6 has an Australian origin, receiving its segment 4 from a reassortment event with an EHDV-2 also from Australia. This reassortant virus likely came to the Americas, where it received its segment 8 from a locally-circulating (as yet unknown) EHDV strain. This virus then may have gained entry into the USA, where it further reassorted with a known locally-circulating EHDV-2, the resulting strain being EHDV-6 Indiana. This study therefore identifies, for the first time, the likely minor parent virus of the EHDV-6 currently circulating in the USA.

“…Overall, our data clearly indicate that EHDV-7 infection caused fever in eight cattle bred at a farm in Fukuoka. In recent decades, epizootics of EHD in cattle have been reported in many countries in Asia and the Mediterranean basin [6,9,10,11,13,16,23,29,35,40].…”
