  1. aAnti-HCV+/n tested for anti-HCV. One person who was not tested for anti-HCV was tested two times positive for HCV RNA with six months interval. This person was therefore counted as positive for anti-HCV and categorized as tested for anti-HCV
  2. bNine persons were not tested for HCV RNA among anti-HCV+ and excluded from analysis
  3. Abbreviations: Anti-HCV+ Hepatitis C virus antibody positive, HCV RNA+ Hepatitis C virus RNA positive, HBsAg+ Hepatitis B surface antigen positive, Anti-HBc+ Hepatitis B core antibody positive, HIV+ Human immunodeficiency virus positive, CI Confidence interval
