Published papers on sexual behavior and HIV/AIDS in sub-Saharan Africa show a remarkable uniformity in their point of departure and their destination. Consequently, this chapter provides important background information for the next chapter, which deals with prevention. Given that the epidemic is being sustained by heterosexual transmission (see Chapter 3), information on sexual behavior is needed to help project the future course of the HIV/AIDS epidemic, to develop more effective prevention strategies, and to provide baseline data for evaluating the effectiveness of alternative prevention strategies. This chapter discusses what we know about sexual behavior and HIV/AIDS in Africa.
