Kuru
Definition
Kuru is a nerve disease that slowly gets worse. It is due to an infectious protein (prion) found in contaminated human brain tissue.
Causes
Kuru is an extremely rare disease. It is almost exclusively found among people from New Guinea, who practiced a form of cannibalism in which the brains of dead people were eaten as part of a funeral ritual.
Kuru causes neurodegenerative changes similar to Creutzfeldt-Jakob disease Similar diseases appear in cows as bovine spongiform encephalopathy (BSE), also called mad cow disease.
The main risk factor for kuru is eating human brain tissue, which can contain the infectious particles.
