title: [Seroprevalence of hepatitis C virus (HCV) in Senegalease blood donors].
abstract: BACKGROUND
  Hepatitis C virus (HCV) is an important problem of public health in the world according to its transmission mode and its pathogenesis. The risk of blood transmission has led to be the systematic screening of blood donors in the world. In Senegal no study about HCV prevalence on the general population and also has been done. The aim of our study was to determine HCV prevalence in blood donors and the rate of co-infection with hepatitis B (HCV/HBV) or with HIV infection (HCV/HIV).
  
  
  METHODS
  This study had been done in the National Blood Transfusion Centre (CNTS) in Dakar. Two different techniques has been used for the assessment HCV: 1/ ELISA technique and 2/ Immunoblot RIBA as confirmation test.
  
  
  RESULTS
  Our study relates to 1565 blood donors recruited in CNTS during 2002. 369 of them were new blood donors with 365 females and 1200 males. The mean average was 30.5 +/- 9.5 years, ranged from 18 to 59 years. HCV ELISA test were positive in 22 plasma samples and one of them were co-infected with hepatitis B (HCV/HBV). Four out of these 22 samples have been confirmed positive to RIBA test and three of them were not determined. HCV seroprevalence were 1.4% after ELISA and 0.25% after RIBA testing. This seroprevalence were similar in male and in female and higher in new blood donors than in regular blood donors.
  
  
  CONCLUSIONS
  Our results reinforce the necessity to screen hepatitis C virus in all Senegalese blood transfusion centres.
