“…There have been few comprehensive analyses of the drivers of disease outbreaks due to EHDV and BTV in the NE and MW US. In cattle in Illinois, BTV and EHDV antibody prevalences were positively associated with temperature and with EHDV, forest patchiness (Boyer et al 2010). Using the Virginia subset (1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006) of the same HD data set that we used in the present study, Sleeman et al (2009) reported direct correlations between HD incidence and average temperature for winter, early summer, and late summer, and an inverse relationship with June precipitation.…”

ABSTRACT:We investigated temporal and spatial trends in reporting of hemorrhagic disease (HD) in the midwestern and northeastern US using a 33-yr (1980-2012) questionnaire-based data set. This data set was supported by an additional 19 yr (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012) of bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) isolation results from clinically affected white-tailed deer (Odocoileus virginianus) in these regions. Both the number of counties that were reported positive for HD and the northern latitudinal range of reported HD increased with time. A similar increase was observed with both the number of states annually reporting HD and the number of counties where HD was reported. Large-scale outbreaks occurred in 1988, 1996, 2007, and 2012, and the scale of these individual outbreaks also increased with time. The predominant virus isolated from these regions was EHDV-2, but the prevalence of EHDV-6, which was first detected in 2006, appears to be increasing. Temporally, the extent of regional HD reporting was correlated with regional drought conditions. The significance of increases in reported HD and the incursions and establishment of new BTV and EHDV in the US currently are unknown.

“…The factors underlying this association were not investigated, but likely relate to WTD habitat utilization and larval development sites for Culicoides species. Other studies have found significant clustering, or patchiness of infection, or outbreaks (Boyer et al 2010, Xu et al 2012). In a 3-year study by Boyer et al (2010), temperature was associated with EHDV and BTV seropositivity in cattle during all 3 years of the study, although there were differing spatial distributions between viruses.…”

In a 3-year study by Boyer et al (2010), temperature was associated with EHDV and BTV seropositivity in cattle during all 3 years of the study, although there were differing spatial distributions between viruses. Furthermore, forest patchiness was associated with EHDV seropositivity in cattle for two of three seasons, and heavy spring rainfall was hypothesized to play a role in the lack of association during the third year, which is supported by other studies (Sleeman et al 2009).…”

Recent spatial statistical modeling of HD in WTD from 1980 to 2007 revealed that wetland cover is likely a critical driver of HD morbidity (Berry et al 2013).…”

Bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) are arthropod-transmitted viruses in the genus Orbivirus of the family Reoviridae. These viruses infect a variety of domestic and wild ruminant hosts, although the susceptibility to clinical disease associated with BTV or EHDV infection varies greatly among host species, as well as between individuals of the same species. Since their initial detection in North America during the 1950s, these viruses have circulated in endemic and epidemic patterns, with occasional incursions to more northern latitudes. In recent years, changes in the pattern of BTV and EHDV infection and disease have forced the scientific community to revisit some fundamental areas related to the epidemiology of these diseases, specifically in relation to virus-vector-host interactions and environmental factors that have potentially enabled the observed changes. The aim of this review is to identify research and surveillance gaps that obscure our understanding of BT and EHD in North America.

“…In North America, C. sonorensis is considered to be the predominant vector for both viruses, although it is recognised that other vectors, for example C. mohave, might be regionally important (82,83,84). Interestingly, however, EHDV infection extends into the Canadian states of Saskatchewan and Alberta, whereas BTV does not (12,82,85,86). In contrast, whereas BTV has recently invaded extensive portions of Europe, EHDV has not and Europe is currently free of EHDV infection despite the presence of the virus on the southern and eastern rims of the Mediterranean Basin (4).…”

SummaryEpizootic haemorrhagic disease (EHD) is an arthropod-transmitted viral disease of certain wild ungulates, notably North American white-tailed deer and, more rarely, cattle. The disease in white-tailed deer results from vascular injury analogous to that caused by bluetongue virus (BTV), to which EHD virus (EHDV) is closely related. There are seven serotypes of EHDV recognised, and Ibaraki virus, which is the cause of sporadic disease outbreaks in cattle in Asia, is included in EHDV serotype 2. The global distribution and epidemiology of BTV and EHDV infections are also similar, as both viruses occur throughout temperate and tropical regions of the world where they are transmitted by biting Culicoides midges and infect a wide variety of domestic and wild ungulates. However, the global distribution and epidemiology of EHDV infection are less well characterised than they are for BTV. Whereas most natural and experimental EHDV infections (other than Ibaraki virus infection) of livestock are subclinical or asymptomatic, outbreaks of EHD have recently been reported among cattle in the Mediterranean Basin, Reunion Island, South Africa, and the United States. Accurate and convenient laboratory tests are increasingly available for the sensitive and specific serological and virological diagnosis of EHDV infection and confirmation of EHD in animals, but commercial vaccines are available only for prevention of Ibaraki disease and not for protection against other strains and serotypes of EHDV.
