Objectives:
This study investigated the sharing of drug preparation equipment as a possible route of hepatitis C virus (HCV) transmission.
Methods:
HCV seroconversion was measured in a cohort of 317 injection drug users who tested negative for HCV antibody at recruitment.
Results:
Cumulative HCV incidence was 16.7% per year. Among those who did not share syringes, HCV seroconversion was associated with sharing drug cookers and filtration cotton (adjusted risk ratio = 5.9; 95% confidence interval = 1.1, 31.7); 54% of HCV infections in injection drug users who did not share syringes were attributable to cooker/cotton sharing.
Conclusions:
Among injection drug users who do not share syringes, an important proportion of HCV infections may be attributed to cooker/cotton sharing.
