We talk more about HIV and AIDS in South Africa with journalist Phillip Van Niekerk (fawn-KNEE-kirk). Recently, the president of South Africa, Thabo Mbeki (TAH-boh mm-BEK-eh) has become very involved in the AIDs policy in his country. Mr. Mbeki is focusing on a medical theory that states that the human immunodeficiency virus, or HIV, does not cause AIDS. Many leading scientists have criticized MR. Mbeki for wasting his time on what they see as a discredited theory about AIDS. The International AIDS conference is scheduled to be held in South Africa this summer.
