No, CJD occurs in humans, and usually only in Libyan Jews. No, coz most of Lybians aren't jew but muslim. Jews eat kosher meat. CJD can come from cannibalism too. No...Kuru comes from cannibalism, not CJD. Most Libyans aren't Jewish but some are and they have the highest tendancy which is still like 1 in a 1,000,000. And Agozer, sure they're not farfetched but that'd be like saying Klebsiella pnuemonie and Mycobacterium pneumonie are the same. They both cause variants of pnuemonia but they aren't the same. Mad cow is CJD-Variant. A single change in a protein can change the identity of something. But for the layman, CJD and Mad Cow are interchangable. But I have to learn to ins and outs of all this so that's why I'm acting like such a biatch. I blame the confusion on relaxed policies of news journalists that cover science. But lets just end this arguement once and for all, Mad Cow is a CJD-Variant and can be interchangable in speech. There, both parties are now satisfied. Kuru's a CJD variant.
