Bluetongue virus, or BTV is similar to Epizootic hemorrhagic disease virus, or EHD, and belongs to the same genus Orbivirus, and family Reoviridae, but they cause two different diseases.

How do you treat EHD in deer?
Virus identification is essential since the signs of EHD can resemble BT and other diseases of agricultural concern, such as Foot and Mouth. There is no treatment for EHD or BT in wildlife populations and no wildlife prevention plan currently exists.
How do you treat bluetongue?

Is EHD treatable?
No, there is no treatment for EHD. In the southern states, where EHD occurs more often, deer can develop immunity to the disease.
What does EHD look like?
Deer with EHD often appear weak, lethargic, and disoriented. Other signs of EHD in deer are ulcers in the mouth or on the tongue, swollen face, neck, or eyelids, and a bluish color to the tongue. Deer with EHD often search for water to combat the fever caused by the disease.
