The Community Outreach Intervention Projects (“COIP”), School of Public Health, University of Illinois at Chicago was founded in 1986 to address HIV/AIDS, particularly among people who use drugs. COIP operates from storefront sites in Austin, Humboldt Park, West Englewood, South Chicago, and Uptown. Other neighborhoods are served by COIP’s motorhome and mobile van units. COIP’s interventions are known for their use of the Indigenous Leader Outreach Model, which employs former drug users to deliver services and assist in conducting research.
