Thank you. That is actually well-covered in the article. The article states this: "The epidemic likely started when one person in a Fore village developed sporadic Creutzfeldt-Jakob Disease, a degenerative neurological disorder similar to kuru." And this: "People have developed variant CJD after eating the meat of cattle infected with mad cow disease. Dr. Ermias Belay, a prion disease researcher with the Centers for Disease Control and Prevention, says that's the only scenario in which there is "definitive evidence" that humans can develop a prion disease after eating the infected meat of another species."
