Key findings
- Sharing needles/syringes and injecting equipment poses a substantial risk to HCV transmission among PWID.
- While needle/syringe sharing is low among PWID, equipment sharing is far more common.
- Those who have tested positive to HCV antibodies are 7.5 times more likely to receptively share needles/syringes than those who tested negative to HCV antibodies, thereby putting themselves at increased risk.
- Harm minimisation interventions and public health messages need to target this behaviour to reduce the risk of HCV infection.
