AIDS in Africa: emerging trends.

This paper reviews the literature on AIDS in Africa. By 29 February, 1988, 9760 cases of AIDS had been reported in Africa. This review addresses the currently accepted belief in the African origin of AIDS, the distribution (cluster) of AIDS in Africa, identified modes of transmission, and changing sexual and drug use behaviors in Africa. There is no conclusive evidence to show that the AIDS virus originated in Africa. Even if the progenitor virus had a habitat in central Africa, certain high-risk sexual behaviors which were introduced in the 60s and 70s may have initiated the infectious process. The distribution pattern does not suggest a transcontinental spread; rather, it suggests a contigual and transatlantic spread. The primary mode of transmission is heterosexual activity. This paper raises a number of questions relating to heterosexual behaviors. Other issues addressed include drug use behavior, homosexuality, and high-risk sexual activities of Africans and foreigners in Africa. Other modes of transmission are transfusion of contaminated blood and blood products, use of nonsterile needles, and perinatal transmission. It is not likely that traditional (folk) medicine will contribute to the spread of AIDS. Traditional doctors use fresh razor blades for cuts and not hollow instruments such as needles. The impact of the political and socioeconomic climate in most of Africa during the 60s and early 70s is evaluated. Finally, we make suggestions for future direction, which include confirmatory testing of HIV Positive samples, conducting clinical epidemiology and social science-based research, and developing innovative education programs that are culturally relevant.
