Chronic Wasting Disease (CWD)

Introduction of CWD; Chronic wasting disease (CWD) is a fatal neurodegeneration of cervical department of infectious spongiform encephalopathy (TSE) (Hamir, et al., 2006). Cervidae family includes elk, Odocolileus hemionus, Ogrey, Odocolileus virginianus, Rocky Mountain Elk, Cervus elaphus nelsoni, Moose, Alces alces shirasi et al (Sigurdon & Aguzzi, 2007). CWD is prion disease. That is, it is a protein-induced infection naturally occurring in deer families (Song & Lawson, 2009).

Chronic wasting disease (CWD) was discovered in 2005 and 2009 in a herd of herds in Hampshire County, West Virginia, Frederick County, Virginia (WVDNR 2011; VDGIF 2013). CWD is a fatal neurological disease that affects other large herbivores such as deer, elk and elk (VDGIF 2013). Long-term impact on deer, elk, elk population is a serious problem for state and federal wildlife management agencies. A deer infected with CWD may take up to 5 years to develop symptoms; CWD may be transmitted between deer and deer, or through contaminated soil and other surfaces (VDGIF 2013). Currently, there is no evidence that CWD infects humans, pets, livestock, but public health officials recommend avoiding human exposures to CWD agents in areas where Deer's CWD is recorded ( VDGIF 2013). These storage areas contain part of the Lee Ranger area of ​​GWNF.

Some Michigan seemingly sporadic young men cases may refer to chronic wasting disease (CWD) from deer or elk, that is, a hunter who is infected with animal prion diseases. CWD is becoming more common in US animal populations. Since hunters eat meat of these animals, prion diseases may proceed from hunters to hunters. Another form of human prion disease is called Kuru disease. They discovered ceremonial cannibalism among the indigenous peoples of New Guinea (especially they eat humans and their brains). When people with sporadic CJD are eaten, sickness may begin. After the symptoms appear, death of about comes about 1 year, but the average incubation period is about 12 years, it will be 40 years. At the end of these ceremonies, this disease almost disappeared in New Guinea.
