Behavioural data were collected through interviewer-administered questionnaires. Characteristics and risk behaviours were compared across cities. Univariate and multivariate analyses explored risk factors associated with HIV and HCV.Results: The prevalence of HIV was 2.6% (95% CI 0.83% to 4.5%) in Rawalpindi (nā€Š=ā€Š302) and zero in Abbottabad (nā€Š=ā€Š102). The prevalence of HCV was significantly higher in Rawalpindi at 17.3% (95% CI 13.0% to 21.6%) than in Abbottabad at 8% (95% CI 2.6% to 13.4%). The prevalence of other STIs was low in both cities, with <2% of participants having current gonorrhoea or Chlamydia and <3% with active syphilis. Injecting risk behaviours were greater in Rawalpindi. An increased risk of HCV was associated with using informal sources as a main source of new needles/syringes (OR 2.8, 95% CI 1.3 to 6.0) compared with pharmacies and a history of drug treatment (OR 3.7, 95% CI 0.9 to 11.6). Reporting symptoms of an STI was associated with decreased odds of HIV in Rawalpindi (OR 0.02, 95% CI 0.03 to 0.9).Conclusions: The findings suggest recent transmission of HIV and HCV and point to the urgent need for the provision of clean needles/syringes to IDUs and a review of how needles/syringes are currently provided via healthcare establishments.
