Risk Correlates of Prevalent HIV, Hepatitis B Virus, and Hepatitis C Virus Infections Among Noninjecting Heroin Users

Abstract

Never-injectors infected with HIV and HBV appear to have become infected mainly through sexual transmission, whereas former injectors appear to have become infected with HIV and HCV mainly though injecting risk and with HBV through both injecting and sexual risk. Interventions targeted at NIUs should prevent unsafe sex as well as the initiation or resumption of injecting. In addition, unhygienic tattooing, which may lead to HCV exposure, should be a focus of prevention efforts.
