Drug use and sexual behaviors among sex partners of injecting-drug users--United States, 1988-1990.

The National AIDS Demonstration Research (NADR) Program of the National Institute on Drug Abuse evaluates community-based outreach and prevention efforts targeted to injecting-drug users (IDUs) and their sex partners. These sex partners who are not IDUs are at substantial risk for human immunodeficiency virus (HIV) infection, particularly if they engage in sexual intercourse without using condoms. In 1990, 1531 of the 42,557 acquired immunodeficiency syndrome (AIDS) cases reported to CDC occurred among sex partners of IDUs, an increase of nearly 32% from 1989 (1). This report summarizes data from the NADR Program characterizing persons who self-reported never having injected drugs themselves but having had sex with a partner who was an IDU.
