A chronic, progressive, fatal central nervous system disease found mainly among the Fore and neighboring peoples of New Guinea, caused by a prion that probably resembles the scrapie agent of sheep, transmissible to nonhuman primates, and believed to be transmitted by ritual cannibalism.
From Fore kúru (literally “trembling, shivering”). Perhaps eventually from Proto-Gorokan *kút(V) (“dangling, shaking”) if cognate with the reduplicated element of Yagaria gúli gúli hu- (“be loose, rattle”).
