PACHECO, Suzy Danielly Barbosa et al. Prevalence of HCV infection and associated factors among illicit drug users in Breves, State of Pará, northern Brazil. Rev. Soc. Bras. Med. Trop. [online]. 2014, vol.47, n.3, pp.367-370.  Epub 11-Abr-2014. ISSN 0037-8682.


Illicit drug users (DUs) are vulnerable to hepatitis C virus (HCV) infection. The shared use of illicit drugs is the main method of HCV transmission.


A cross-sectional study was conducted in Breves, in northern Brazil. We surveyed 187 DUs to determine the prevalence of and factors associated with HCV infection.


The prevalence of anti-HCV antibodies was 36.9%, and the prevalence of hepatitis C virus-ribonucleic acid (HCV-RNA) was 31%. Hepatitis C virus infection was associated with tattoos, intravenous drug use, shared use of equipment for drug use, drug use for longer than 3 years, and daily drug use.


Strategies for preventing and controlling HCV transmission should be implemented among DUs.
