For over 30 years, almost all studies of HIV/AIDS epidemics and programs have focused on one key population (e.g., injectors, men who have sex with men, or heterosexuals) in isolation from other key populations. This approach has significantly limited scientific understanding of the fundamental dynamics of HIV/AIDS epidemics. Research analyses have suggested that HIV/AIDS epidemics and programs in one key population may affect epidemics and programs in other key populations. Likewise, programs targeting one key population may affect epidemics in other key populations. This study pioneered a novel line of high-impact epidemiologic, programmatic, and policy research on whether and how HIV/AIDS epidemics and programs affect one another across three key populations (i.e., men who have sex with men (MSM), people who inject drugs (PWID), and heterosexuals) in the US. Findings will open up new arenas for intervention, including interventions that seek to prevent epidemics in one key population from affecting epidemics in other key populations, and that maximize positive effects of interventions across key populations.
