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]
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]
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]
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 ...
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 ...
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 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 contract this disease through the bite of a deer fly (Chrysops spp.) or mango fly, the vectors for Loa loa. The adult Loa loa filarial worm can reach from three to seven centimetres long and migrates throughout the subcutaneous tissues of humans, occasionally crossing into subconjunctival tissues of the eye where it can be easily ...
