Bluetongue Virus (BTV) and Epizootic Hemorrhagic Disease Virus (EHDV) are two viruses belongbelonging to the genus Orbivirus that and are transmitted via insect vector, the Culicoides biting midge, causing disease in domestic and wild ruminantse. These infections can lead to significant morbidity, mortality, and production losses in livestock, with economic consequences for cattle and sheep industries. Despite their growing impact due toAs globally re-emerging diseases of domestic and wild ruminants driven by environmental and anthropogenic changes, little is known of the prevalence of these viruses in North American bison (Bison bison). We present the first crosssectional survey of BTV and EHDV seroprevalence in North American bison, with samples collected from 287 animals across 9 herds in 7 U.S. states from September to November 2023. Using competitive enzyme-linked immunosorbent assays (cELISA), we detected seroprevalence rates of 56.5% for BTV and 57.5% for EHDV. Logistic regression analysis revealed age as a significant
