3. Kuru is a disease which affects the brain. It was endemic among the Fore tribe of Papua New Guinea and
was universally fatal. It is characterized by headaches, joint pains and shaking of the limbs. In fact, the
word kuru means ―trembling with fear‖ in the language of the Fore people. Before its eradication, kuru was
more prevalent in women and children than in men. It is believed by some scientists that the disease
spread easily in the Fore people due to their cannibalistic funeral practices. The increased infection in
women and children is thought to be due to the fact that while the men of the village ate the flesh of the
deceased, the women and children ate the brains. With elimination of these practices, kuru disappeared
among the South Fore within a generation.
