Albinos make up about one in 4,000 people in South Africa and perhaps one in 5,000 in Nigeria

Three men armed with machetes killed an 8-year-old albino boy in Burundi recently and are believed to have smuggled his limbs to Tanzania, where witch doctors use albino body parts for potions. At least 35 albinos were killed in Tanzania in 2008, prompting police officials to set up an emergency hot line and a program to distribute free cell phones to all albinos. Albinism, a genetic disorder characterized by lack of melanin pigment in the skin, hair, and eyes, is listed as a rare disease by the National Institutes of Health—meaning it affects fewer than 200,000 Americans. Around the world, between one in 17,000 and one in 20,000 people are albinos. The prevalence in parts of Africa, however, is far higher than the global average. Albinos make up about one in 4,000 people in South Africa and perhaps one in 5,000 in Nigeria. According to a 2006 review published in the journal BMC Public Health, the prevalence in Tanzania is one in 1,400, but this estimate is based on incomplete data. Since Tanzania's total population is more than 40 million, that would suggest an albino community of about 30,000. A census is under way, however, and the Albino Association of Tanzania believes the total figure could be more than 150,000. A study published in 1982 notes that albinism is less common among the South African Zulu and Xhosa tribes (one in 4,500) than the Swazi and Sotho-Tswana tribes (one in 2,000). In Zimbabwe, about four-fifths of albinos belong to the majority ethnic group, the Shona.
