Epizootic hemorrhagic disease virus (EHDV) is a Culicoides biting midge-transmitted orbivirus (family Reoviridae) of wild and domestic ruminants and is an important pathogen of white-tailed deer (Odocoileus virginianus). Historically, only two serotypes, EHDV-1 and EHDV-2, have been known to be endemic in the US. However, in 2006, an exotic serotype (EHDV-6) was first detected in the US by a long-term passive surveillance system for EHDV and bluetongue viruses. Here we report EHDV-6 detections made through these passive surveillance efforts by the Southeastern Cooperative Wildlife Disease Study (University of Georgia, Athens, Georgia, USA) and the National Veterinary Services Laboratories (US Department of Agriculture, Ames, Iowa, USA) over a 10-yr period (2006-15). The results demonstrated that EHDV-6 was detected from ruminants every year since 2006 and was widespread in the central and eastern US, providing evidence that EHDV-6 is likely now established in the US.
流行性出血病病毒（EHDV）是一种由蠓传播的反刍动物环状病毒（呼肠孤病毒科），是白尾鹿（弗吉尼亚鹿）的重要病原体。历史上，已知只有两种血清型，即EHDV - 1和EHDV - 2在美国呈地方流行性。然而，2006年，一种外来血清型（EHDV - 6）首次在美国通过一个针对EHDV和蓝舌病病毒的长期被动监测系统被检测到。在此，我们报告了美国东南部野生动物疾病合作研究中心（美国佐治亚大学，雅典，佐治亚州）和国家兽医服务实验室（美国农业部，艾姆斯，爱荷华州）在10年期间（2006 - 2015年）通过这些被动监测工作所检测到的EHDV - 6情况。结果表明，自2006年以来每年都从反刍动物中检测到EHDV - 6，且该病毒在美国中部和东部广泛传播，这证明EHDV - 6现在可能已在美国定殖。
