REYNOLDSBURG, OH: In early September, the ADDL had its first detection of epizootic hemorrhagic disease virus (EHDV) of 2021. The detection occurred in a white-tailed deer submitted by the Ohio Department of Natural Resources, Division of Wildlife. Typing revealed it is EHDV serotype 2 (EHDV-2).
EHD is a viral infection (genus Orbivirus, family Reoviridae) caused by EHDV that is primarily transmitted by biting midges (genus Culicoides) to several species of cervids, especially white-tailed deer. Major geographic expansion of EHDV has occurred during the past 40 years, associated with increasing frequency of large-scale outbreaks. Typically, outbreaks are caused by EHDV-2 in Ohio in the late summer and early fall. Occasionally, EHDV-1 has also been detected in Ohio in the past. In 2020, Ohio had its first detection of EHDV-6, an emerging serotype first documented in the United States in 2006.
If you see dead/sick deer in your area, reporting this helps ODNR track potential disease outbreaks. You can report dead/sick deer by calling 1-800-WILDLIFE or by filling out the ODNR Wildlife Species Sighting Report.
For more information about EHD, visit the ODNR Wildlife Diseases EHD webpage.
The ADDL has several assays available to test for the presence of EHDV RNA, EHDV antigen, and EHDV antibodies. Contact the lab at firstname.lastname@example.org or visit the Tests and Fees page to learn more about available tests.
