Over half of the people living with HIV/AIDS in the world are found in sub-Sahara Africa, according to statistics released by a Tanzania-based health body. Dr Steven Shongwe, the executive secretary of the Commonwealth Regional Health Community for East, Central and Southern Africa (ECSA Health Community), said that a recent survey among the 14 member countries in the body indicated that the region has an estimated 30 million people suffering from HIV/ AIDS, accounting for about 50 per cent of the worldwide total.
