June 13 is United Nations International Albinism Awareness Day, the 10th anniversary of the launch of the day to combat stigma, discrimination and violence toward persons with albinism. Persons with albinism, a congenital condition that affects one in 18,000 to 20,000 people worldwide, still face prejudice and suffer attacks and killings, while poverty prevents many from obtaining life-saving sunscreen, UN experts say.
