Vancouver Injection Drug Users Study (VIDUS)
VIDUS is a community-recruited cohort study of people who inject drugs (PWID) in Vancouver, Canada. Beginning in May 1996, people who had injected illegal drugs at least once in the previous month and resided in the Greater Vancouver region were recruited into VIDUS through self-referral and street outreach. As of February 1997, 1,006 people who inject drugs (PWID) had completed baseline interviews and provided blood specimens. Participants are followed up every 6 months.
