Yeah, because scrapie doesn't resemble a virus, so it doesn't have the same survival concerns. A protein in an exceptionally low-energy conformation is more robust than a ring of RNA, film at 11.
Anyway, fun fact, the prion that causes scrapie is extremely similar to the ones that cause mad cow disease (transmissible to humans) and Creutzfeldt-Jakob disease (human disease). So yes, we're very, very lucky, so far. Sleep tight.
