title: Prevalence of hepatitis B virus and hepatitis C virus among blood donors at a tertiary care hospital in India: a five-year study.
abstract: BACKGROUND
  Hepatitis B virus (HBV) and hepatitis C virus (HCV) are important transfusion-transmissible infections. This study was performed to assess the prevalence of HBV and HCV seropositivity among blood donors at a tertiary care hospital-based blood bank in India.
  
  
  METHODS
  The blood donation records over 5 years (2005-2009) were reviewed, retrospectively, for the prevalence and yearly trends of HBV and HCV seropositivity.
  
  
  RESULTS
  A total of 94,716 donations were received. The overall number of HBV-seropositive donations was 1353 and that for HCV was 537, with the prevalence rates of 1.43% for hepatitis B surface antigen (HBsAg) and 0.57% for HCV. The seropositivity rate was higher in the replacement donors compared to the voluntary donors. The annual rates showed decreasing trends in case of HBsAg, but in case of HCV, there was a linear increase.
  
  
  CONCLUSIONS
  Our study raises serious concerns regarding the HBV and HCV prevalence in our country. Although HBV showed decreasing trends, it cannot be relied upon because the donors were screened only for HBsAg. HCV is clearly on the rise. Stringent measures need to be taken on urgent basis including dissemination of information, strict screening of blood, inclusion of antibody to hepatitis B core antigen and other sensitive markers to the screening protocol, and better donor recruitment.
