To identify risk factors for infection with the human immunodeficiency virus (HIV) and for progression to the acquired immunodeficiency syndrome (AIDS) among intravenous drug users, we established a cohort in Baltimore Maryland in 1988–1989. Intravenous drug users were recruited by extensive community outreach to undergo interview and confidential HIV testing in a special study site. During 13 months of recruitment, 2,921 intravenous drug users were enrolled of whome 24 percent were HIV seropositive; 90 percent returned to receive test results. Methodological issues for enhancing recruitment and retention of drug users are discussed.
