Vertical transmission of hepatitis C virus infection

Since the virus responsible for non-A, non-B hepatitis,vas cloned in 1989, much has been learnt about the epidemiology, diagnosis and clinical spectrum of hepatitis C virus (HCV) infection. As the routes of transmission are elucidated, specific groups of children as well as adults are known to be at particular risk of infection. The women most at risk of HCV infection are those with a history of injecting drug use. Mother-to-child transmission has been documented, although the exact risk has not been quantified, and the factors influencing the risk remain to be evaluated This article reviews current knowledge on vertical transmission of HCV, and provides some guidelines on the management of infants born to women infected with the virus.
