Epizootic hemorrhagic disease (EHD) is a hemorrhagic disease of white-tailed deer (Odocoileus virginianus) caused by an infection of a virus from the genus Orbivirus subsequently called Epizootic hemorrhagic disease virus (EHDV).

2022年7月20日 · Hemorrhagic disease in deer, also known to many deer hunters as EHD or bluetongue, is a serious viral disease of deer that is spread by biting flies. Outbreaks occur seasonally with the life cycle of the insects that spread the virus and usually peak in …

EHD is a viral disease of white-tailed deer that is transmitted by a biting midge in the family Culicoides. Outbreaks are most common in the late summer and early fall when the midges are abundant. Deer can DIE. QUICKLY within 8 to 36 hours. EHD is TRANSMITTED to deer by Culicoides midges.

2012年9月28日 · Epizootic hemorrhagic disease viruses (EHDV) are widespread in white-tailed deer and periodically cause serious epidemics in wild populations as well as affecting farmed deer populations. EHD can also cause disease in cattle. Lesions mimic those observed with BVDV, plant photosensitization, adenovirus, Blue Tongue virus and Foot and Mouth Disease.

Hemorrhagic disease (HD) is a general term for illness caused by two related viruses: Epizootic Hemorrhagic Disease virus (EHD) and bluetongue virus (BT). HD primarily affects white-tailed deer and can cause significant mortality events, particularly in the northern United States.

2018年3月29日 · Epizootic hemorrhagic disease (EHD) is a native disease that causes significant morbidity and mortality among deer in North America. The disease is caused by EHD viruses. The virus is transmitted primarily by biting midges (small flies) of the genus Culicoides.

2023年8月16日 · These are the leading indicators that whitetail deer are dying from epizootic hemorrhagic disease, better known as EHD and sometimes called "blue tongue."

EHD is a viral, often fatal, disease of white-tailed deer that is transmitted by biting midges (Culicoides spp.), also called no-see-ums or punkies. The disease is not spread directly from deer to deer and humans cannot be infected through contact with deer or bites from midges.

2024年7月16日 · Epizootic hemorrhagic disease (EHD) and bluetongue viruses (BTV) are spread by a tiny, flying, blood-feeding insect called a midge. These midges in the family Culicoides become abundant in late summer.

Caused by the bite of an infected midge (a type of fly) and once there has been a hard freeze, these insects die off for the winter, eliminating new cases of EHD. One of the most common diseases of white-tailed deer in the United States.
