This study will use the methods of Implementation Science - research synthesis, mathematical modeling and simulation, and comparative effectiveness analyses - to determine how best to constitute a portfolio of interventions for the prevention and control of HCV and its consequences while taking into limited resources and underlying epidemiologic and social network features account. A dissemination plan will make extensive use of technology, including social media, and guidance from key stakeholders.
