Equipment sharing among people who inject drugs (PWID) is a key risk factor infection by hepatitis C virus (HCV). Both the effectiveness and-effectiveness of interventions aimed at reducing HCV transmission in this (such as opioid substitution therapy, needle exchange programs or treatment) are difficult to evaluate using field surveys. Ethical and complicated access to the PWID population make it difficult to epidemiological data. In this context, mathematical modelling of HCV is a useful alternative for comparing the cost and effectiveness various interventions. Several models have been developed in the past few. They are often based on strong hypotheses concerning the population. This review presents compartmental and individual-based models in to underline their strengths and limits in the context of HCV infection PWID. The final section discusses the main results of the papers.
