Modeling hepatitis C virus transmission among people who inject drugs: Assumptions, limitations and future challenges

Figures & data

Figure 1. If the initial prevalence of heterogeneous S-I deterministic compartment models is calibrated by varying the transmission risk (effective contact) parameter (β), then for a fixed initial prevalence and proportion of the population at high risk β will be a decreasing function of the average length of injecting career (1/μ) and the relative difference in transmission risk (${\displaystyle \text{Γ}}$).
