vitiligo in USA

vitiligo is a skin pigmentation disorder in which melanocytes in the skin, the mucous membranes and the retina are destroyed. As a result, white patches of skin appear on different parts of the body. The hair that grows in areas affected by vitiligo usually turns white.

About 1 to 2 percent of the world's population, or 40 to 50 million people, have vitiligo. In the United States of America (USA), 2 to 5 million people have the vitiligo skin disorder. Ninety-five percent of people who have vitiligo develop it before their 40th birthday. The disorder affects all races and both sexes equally.
