title: [Hepatitis virus C infection in children].
abstract: The prevalence of hepatitis C virus(HCV) infection has been becoming much lower in childhood. Blood transfusion was the principal transmission route of HCV in children. Since the year of 1989, screening of the blood products for HCV antibodies has markedly reduced transfusion-related HCV infection. Mother-to-infant transmission occurs in less than 10% of infants born to HCV-infected mothers. The maternal viral load is the most important factor determining the risk. The natural history and the outcome of HCV infection in childhood dependent on host and viral factors. The rate of progression to chronicity is 60% in post-transfusion infection and 80% in vertical infection. Experience of interferon therapy of chronic hepatitis C in children is limited, with about 50% having a sustained response to the therapy.
