One potential means of reducing risk HCV transmission IDU serosorting, whereby preferentially share equipment with persons like status. Methods We surveyed Seattle area recruited by respondent-driven sampling as part the National HIV/AIDS Behavioral Surveillance system in 2005.

Thirty-seven self-reported HCV-positive that their sharing partner was also and 7% HCV-negative partner. Among 11% 23% negative The disproportionate tendency to persisted after control characteristics associated positivity stratified logistic regression analyses. equipment, 39% had intentionally based on knowledge concordant Conclusions conclude measurable degree serosorting occurring IDU. Promotion may be useful harm reduction strategy continue practice If judged efficacious, would provide further rationale encourage support testing
