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. [2]
Found in deer in northern Colorado and southern Wyoming in the 1990s, chronic wasting disease (CWD) has been recorded in free-ranging deer, elk and moose in at least 32 states across all parts of ...
TSEs in non-human mammals include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle – popularly known as "mad cow disease" – and chronic wasting disease (CWD) in deer and elk. The variant form of Creutzfeldt–Jakob disease in humans is caused by exposure to bovine spongiform encephalopathy prions. [4] [5] [6]
Scientists have warned a “zombie deer disease” could spread to humans after hundreds of animals were infected with the illness in the US over the last year.. Chronic wasting disease (CWD ...
The disease is not known to infect humans. Although they do not harm the meat, fibromas are repulsive to most people, so they discourage them from consuming the deer. [7] Some domesticated animals (cattle, dogs, etc.) are subject to "warts" common to their species. Fibromatosis of deer is quite unlikely to be infectious to domestic animals. [7]
The threat of so-called “mad cow disease” has all but faded from the collective memory, after its appearance in U.K. cattle in 1986. Human deaths from the scourge, caused by eating ...
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.
The CDC reported over 30,000 new cases of the disease in 2016 alone, the majority of which were contracted in the summer months, which is when ticks are most likely to bite humans. [15] While adult deer ticks are more likely to carry and transmit Borrelia burgdorferi, it is more common for the hard-to-spot nymphal stage to infect humans. [16]
