You hit the nail right on the head. Are we to believe that the nations of sub-Saharan Africa, most of which can't afford even enough aspirin to treat the common cold and headaches, can afford the sort of testing kits and equipment requisite to a diagnosis of AIDS? The disease has become so highly politicized that the UN, WHO, and even the CDC have virtually dictated that ANY fever of unknown etiology, and ANY condition the nature of which is not immediately apparent, be labeled AIDS. And this in a part of the world in which tropical fevers of countless varieties carry off the residents with the speed and regularity of taxis at a city airport. The numbers for so-called AIDS cases in Africa are cooked and fraudulent.
There is a pandemic of HIV/AIDS in Africa. Please see NIAID Fact Sheet: The Evidence That HIV Causes AIDS for some detailed information about AIDS in Africa. (Look down the page for the section with the heading: In developing countries, patterns of both rare and endemic diseases have changed dramatically as HIV has spread, with a far greater toll now being exacted among the young and middle-aged, including well-educated members of the middle class.)
