WVC 91st Annual Conference
Epizootic hemorrhagic disease (EHD) virus is an orbivirus transmitted by the vector Culicoides spp. In North America, EHD is recognized as a disease primarily affecting pen raised white-tailed deer, but it can impact other wildlife species and domestic cattle. Clinical disease in Texas cattle has not been noted but periodic outbreaks in other states have prompted Texas cattle producers to question their risk. A study was conducted to estimate the proportion of Texas cattle exposed to epizootic hemorrhagic disease virus serotype 2 by observing seroprevalence in auction markets.
