An investigation by Toward Freedom Magazine of the AIDS epidemic in Africa reveals that sloppy research may inflate the reported number of AIDS cases on the continent. The World Health Organization estimates that 23.3 million people in Africa have AIDS. However, that estimate is "based on the most fragile of foundations. [The WHO's] definition of AIDS in Africa differs decisively from AIDS in the West. The WHO's clinical definition of AIDS in Africa is not based on an HIV test but on the combined symptoms of prolonged fever, persistent cough and others; none of which are uncommon in Africa."
