AIDS in Africa: Evidence for heterosexual transmission of the human immunodeficiency virus
Since its initial recognition in 1981, acquired immunodeficiency syndrome (AIDS) has become a global epidemic. Nearly 40,000 cases have been reported from over 85 countries on five different continents. Presently, an estimated 5–10 million people worldwide have been infected with the causative agent, referred to as the human immunodeficiency virus (HIV).1,2 From natural history studies, it can be expected that at least 10–30% of these HIV-infected individuals may develop AIDS within the next three years,3–6 resulting in a cumulative number of more than one million cases of AIDS worldwide by 1990. With the present lack of effective curative therapy or a vaccine, this disease now represents one of the most serious epidemics of the century.
