HIV risk practices of male injecting-drug users who have sex with men--Dallas, Denver, and Long Beach, 1991-1994.

As of June 1995, a total of 31,024 cases of acquired immunodeficiency syndrome (AIDS) had been reported in the United States among male injecting-drug users (IDUs) who also reported sexual contact with other men (1). Although male IDUs who report male sex partners have accounted for 7% of all AIDS cases and for 21% of cases reported among IDUs, the characteristics and risk practices of male IDUs who have sex with men (MSM) have not been clearly determined (2-4). To better characterize this group of men with multiple risk factors for human immunodeficiency virus (HIV) infection, data collected during February 1991 through June 1994 from three sites--Dallas; Denver; and Long Beach, California--were analyzed as part of the CDC-sponsored AIDS Community Demonstration Projects (5,6). This report summarizes results of that analysis.
