Deer infected with CWD may be called "zombie deer" because the disease leads to weight loss, lack of coordination, stumbling, listlessness, weight loss, drooling, and lack of fear of people.
A deer may not show any signs of CWD until 18 to 24 months after becoming infected, according to the U.S. Geological Survey. Arguably the most obvious sign is drastic weight loss, or “wasting.”
Researchers reported the death of two hunters who ate venison infected with chronic wasting sisease or "zombie deer disease," raising questions about whether the disease may be transmissible to ...
Chronic wasting disease (CWD), sometimes called zombie deer disease, is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and include similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt–Jakob disease (CJD) in humans, and scrapie in sheep.

In general, deer infected with EHD lose their appetite, lose their fear of people, grow weak, show excessive salivation, develop a rapid pulse, have a rapid respiration rate, show signs of a fever, which includes lying in bodies of water to reduce their body temperature, become unconscious, and have a blue tongue from the lack of oxygen in the ...
These symptoms develop about 7 days after the animal was exposed to the virus and 8–36 hours after the onset of initial observable signs; deer progress into a shock-like state, collapse and die. [2] Examinations of infected deer suggest the virus interferes with normal blood circulation and normal blood clotting mechanisms.
The disease is spread between deer through direct contact and environmental contamination from infected saliva, urine and feces, and can also be spread through the transportation of hunter ...
Humans are most often infected by tick/deer fly bite or through handling an infected animal. Ingesting infected water, soil, or food can also cause infection. Hunters are at a higher risk for this disease because of the potential of inhaling the bacteria during the skinning process.
