Interventions used to target drug-related infectious diseases

Interventions where there is evidence of benefit in responding to durg-related infectious diseases and where we can have a high or reasonable confidence in the available evidence, are highlighted in a bolder frame namely HIV and HCV treatment, opioid agonist treatment, retention and continuity of care, needle and syringe programmes and HBV vaccination. Much of the current evidence on interventions listed in this figure is either emerging or deemed insufficient, in part because of the practical and methodological difficulties of conducting research, especially in developing randomised controlled trials (see Spotlight on... Understanding and using evidence) and also because service delivery models often differ considerably.
