Introduction:
Because of the severe health consequences of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and the costs of lifelong treatment, inexpensive and effective HIV prevention is bound to be cost-effective. But what constitutes HIV prevention, and can it be affordable and effective? The use of condoms that cost a few cents and prevent a young adult from acquiring a chronic and fatal disease will, over time, be cost saving. Avoiding sex with someone who is infected with HIV/AIDS will be even  more so. What can be done to get people to use condoms? What can be done to facilitate the avoidance of risky sexual encounters?
