title: Viral hepatitis in a Canadian street-involved population.
abstract: BACKGROUND
  Data on the prevalence and compliance with management of viral hepatitis in the street-involved population are limited.
  
  
  METHODS
  Hepatitis A (HAV), B (HBV) and C (HCV) serology and compliance with HBV vaccination were documented in 533 street-involved individuals.
  
  
  RESULTS
  The mean age of the study population was 25.7 years (range: 11-65) and 53% were female. Serologic evidence of HAV infection was present in 53%; HBV, 12% (3% ongoing infection); and HCV, 17%. HAV infections were associated with Aboriginal/Metis ethnicity and age over 25 years; HBV with injection drug use (IDU); and HCV with IDU, sex trade work and age over 25 years. Compliance with three-step HBV vaccination was 98%, 77% and 63%.
  
  
  CONCLUSIONS
  HAV, HBV and HCV are common infections in urban street-involved persons. Successful HBV (and presumably HAV) vaccination can be achieved in the majority of this population, but concerns exist regarding compliance with more long-term, parenterally-based antiviral therapies.
