I am completely asymptomatic and have never suffered even one moment of CJD or other prion-related illness. Up until a couple of years ago, when I was refused from donating blood due to this new mandate, I had never heard of the condition and had donated at least 5 gallons of blood previously. Further, there is no record of any prion-based illness ever being transmitted via blood transfusion, I had received no reports of anyone becoming ill as the result of using my blood, and there is not even any test for the condition that I know of.
I find it very hard to believe that any disease could allegedly have an incubation period of 23 years.
No wonder the blood banks are so chronically short of product - the chicken**** rules and hassle laid down by some wizened bureaucrat somewhere prohibit many otherwise willing potential donors from helping out.
I can state with some confidence that if I drop dead tomorrow, it won't be because of CJD.
