Detailed explanation-1: -CWD prions may remain infectious in soil for at least two years but likely longer. Prion diseases found in humans (such as Kuru and Variant CJD) are known to have incubation periods of several decades.
Detailed explanation-2: -Transmission of BSE BSE is not a contagious disease and therefore is not spread through casual contact between cattle or with other species. The primary route of spread of classical BSE infection in cattle is feed contaminated with the infectious agent.
Detailed explanation-3: -This abnormal accumulation of protein in the brain can cause memory impairment, personality changes, and difficulties with movement. Experts still don’t know a lot about prion diseases, but unfortunately, these disorders are generally fatal.
Detailed explanation-4: -Inherited CJD Between 10% and 15% of CJD cases are inherited. The disease can develop if a change occurs in the gene that controls the formation of prion proteins.
