In an extended network of people who inject drugs (PWID), successful hepatitis C virus (HCV) treatment as prevention should incorporate the baseline HCV prevalence and will achieve greatest benefit when coverage is expanded, a recent study found. 5 graph models were fit using 1,574 PWID in Hartford, CT. The effectiveness of 7 treatment-as-prevention strategies on reducing HCV prevalence over 10 years and 20 years was compared to no treatment. Researchers found:
- At the highest baseline HCV prevalence in PWID (85%), expansion of treatment coverage does not substantially reduce HCV prevalence for any treatment-as-prevention strategy.
- However, when baseline HCV prevalence is ≤60%, treating >120 individuals per 1,000 PWID per year would likely eliminate HCV within 10 years.
- Assigning treatment randomly to PWID is better than targeting those with the most injection partners.
