Kuru is a rare, incurable, and fatal neurodegenerative disorder that was formerly common among the Fore people of Papua New Guinea. Kuru is a form of prion disease which leads to tremors and loss of coordination from neurodegeneration. The term kΓΊru means βtremblingβ and comes from the Fore word kuria or guria ("to shake").[2][3] It is also known as the "laughing sickness" due to the pathologic bursts of laughter which are a symptom of the infection.
It is now widely accepted that kuru was transmitted among the Fore people via funerary cannibalism. Deceased family members were traditionally cooked and eaten, which was thought to help free the spirit of the dead.[4] Women and children usually consumed the brain, the ***** in which infectious prions were most concentrated, thus allowing for transmission of kuru. The disease was therefore more prevalent among women and children.
