Part III Impediments to Research and Intervention In Parts ~ and II of this report, we discussed the two primary modes of transmission of HIV infection: sexual activity and IV drug use. We also documented the incomplete state of scientific knowledge about those behaviors and the behavioral interventions that might retard HIV's future spread. Understanding the behaviors and intervening to modify them are necessary to control the spread of HIV infection. Yet sexual behavior and drug use occur in a social context of strong and often conflicting beliefs that can create barriers to both under- standing and intervention. In this part of the volume, we consider some of those barriers. Chapter 6 describes some of the obstacles to adequate support of relevant behavioral and social research and presents recommendations to overcome them. Chapter 7 describes the barriers to potentially effective interventions to control the AIDS epidemic. Our purpose is to suggest that the understanding and prevention of AIDS must ultimately be seen in a broader context of cultural, political, and social realities.
