KURU

Here is an article from NPR that clams that the cause of KURU is cannibalism.

FTA:

"When researchers made their way to those villages in the 1950s, they found something disturbing. Among a tribe of about 11,000 people called the Fore, up to 200 people a year had been dying of an inexplicable illness. They called the disease kuru, which means 'shivering' or 'trembling.'"

"Lindenbaum had a hunch about what was going on, and she turned out to be right. It had to do with funerals. Specifically, it had to do with eating dead bodies at funerals."

"In many villages, when a person died, they would be cooked and consumed. It was an act of love and grief."
