title: Trend of transfusion transmitted infections frequency in blood donors: provide a road map for its prevention and control.
abstract: BACKGROUND
  Transfusion transmitted infections create significant burden on health care system. Donor selection is of paramount importance because infected individuals serve as an asymptomatic reservoir and a potential source of transmission.
  
  
  METHODS
  A retrospective study was carried out in healthy blood donors in the Lady Reading Hospital Peshawar, Pakistan over a period of three and a half years i.e., from January 2008 to June 2011, to determine the prevalence of HBV, HCV, HIV and syphilis in order to provide information for relevant polices.
  
  
  RESULTS
  Out of 1,27,828 sample of blood donors, recorded mean prevalence for HBs Ag, anti-HCV, anti-HIV and syphilis was 2.68%, 2.46%, 0.06% and 0.43%, respectively, with an increasing trend in frequencies of transfusion transmitted infections (TTIs).
  
  
  CONCLUSIONS
  This study reflects that blood transfusion is one of the leading risk factor of spread of the TTIs, which showed the need and importance of the mandatory screening of these infectious markers in blood donations.
