Interpretive Summary:

Technical Abstract: The Arthropod Borne Animal Diseases Unit (ABADRU) mission is to solve major endemic, emerging, and exotic arthropod-borne disease problems in livestock. The ABADRU has four 5-year project plans under two ARS National Research Programs; Animal Health NP103 and Veterinary, Medical, and Urban Entomology NP 104. These plans include research on bluetongue virus (BTV; exotic and domestic), epizootic hemorrhagic disease (EHD), vesicular stomatitis virus (VSV), and Rift Valley fever virus (RVFV). Transmission of arboviruses and disease events are largely driven by complex and often unknown factors related to vector biology and ecology, as well as host, virus and environmental factors. Bluetongue virus and epizootic hemorrhagic disease virus (EHDV) are arthropod-transmitted virus in the genus Orbivirus of the family Reoviridae. Recent epidemiological and clinical observations will be summarized. Current research projects directed towards the viral agents and respective vectors will also be summarized. While Culicoides sonorensis is the only confirmed Orbivirus vector in North America, additional Culicoides spp. likely play a role in agent transmission and numerous suspected vectors exist. The aim of this presentation is to discuss what we know, but more importantly what we don’t know, about the epidemiology and transmission of Orbiviruses among domestic and wild ruminants in North America. In recent years, changes in the pattern of Orbivirus infection and disease have forced the scientific community to revisit some fundamental areas of research especially regarding disease pathogenesis, epidemiology, vector competence and virus ecology. These research efforts will facilitate development of effective intervention and prevention strategies.
