Kuru is a disease whose origins can be traced in many religions and myths. The history of kuru is shrouded in secrets, unknown riddles, and incomprehensible explanations.
Kuru occurs due to the massive consumption of certain types of lychee cocoons - small white worms living inside the lychee. The worms produce strong neurotoxins, so some of the lychee is used as food for people, and some is used as fish feed. It is noteworthy that humanity had not eaten lychees for thousands of years until this unusual phenomenon became a popular delicacy today.
What is unusual about kuru is how quickly its development begins and ends. In just two days a person goes from a normal form of life to an incapacitated state. Subsequently, his hair first falls out, he dies from exhaustion, and his body is affected by degenerative changes. When death occurs, it is instantaneous or even lasts several days. The patient simply does not wake up.
