In reality they think it was around since the thirties but the spread of HIV is slow. It is not this disease we are dealing with now.
The cause of scrapie, as with other transmissible spongiform encephalopathies, is unknown and is a matter of debate;[15] the agent is very difficult to destroy with heat, radiation and disinfectants, does not evoke any detectable immune response, and has a long incubation period of between 18 months and 5 years.[16] The agent is thought to be much smaller than the smallest currently known virus and the prevailing theory is that it is caused by a misfolded protein called a prion.
