What is EHD and How Does it Spread Among Deer?

Epizootic Hemorrhagic Disease (EHD), and Bluetongue are common viral diseases of deer. White-tailed deer get EHD, while Bluetongue is a well-known disease of domestic sheep, cattle, and goats, in addition to affecting deer.

Transmission is spread by Culicoides gnats which thrive during hot-dry conditions where deer gather near water sources. The gnats are found in wet, muddy areas where deer congregate in late summer and early fall.

Symptoms of Illness From EHD Include:

Deer in the early stages may appear to be lethargic, disoriented, lame, or even unresponsive to hunters. Excessive salivation and foaming at the mouth are signs of infection.

The disease often kills deer so quickly -- within a day or two -- they may still be in very good body condition. In other cases, they may not die, just become sick and stop eating, resulting in emaciation.

Avoid Shooting or Consuming Any Animals That Appear to Be Sick.
