Objective: To measure HIV prevalence and related risk behaviors among male injection drug users (IDUs) in Cairo, Egypt in the context of the first survey wave of an integrated biological and behavioral surveillance system.
Design And Methods: Given the hidden nature of injection drug use, we used the peer-referral methodology of respondent-driven sampling in a cross-sectional study to recruit a sample of male IDUs in Cairo between May and August 2006. Behavioral data were collected through face-to-face interviews and serum was obtained for HIV antibody testing.
