Albino body parts are highly valued in witchcraft and can fetch a high price. Superstition leads many to believe albino children are ghosts who bring bad luck. Some believe the limbs are more potent if the victims scream during amputation, according to a 2013 United Nations report. Albinism is a congenital disorder affecting about one in 20,000 people worldwide who lack pigment in their skin, hair and eyes. It is more common in sub-Saharan Africa and affects about one Tanzanian in 1,400. United Nations officials estimate about 75 albinos have been killed in the east African nation since 2000 and have voiced fears of rising attacks ahead of this year's election, as politicians seek good luck charms from witch doctors.
