Core Tip

Core tip: Hepatitis C virus (HCV) infection is a major global health issue. World Health Organization estimates that the worldwide prevalence is 1%-8% in pregnant women and 0.05%-5% in children. Vertical transmission becomes the leading cause of childhood HCV infection. Current understanding of the epidemiology of mother-to-child transmission of HCV is limited. At present, no clinical intervention has been clearly studied and proved to reduce the vertical transmission risk. Though universal screening is controversial, selective antenatal HCV screening on high-risk populations is highly recommended and should be tested probably. This review provides the current knowledge and perspectives of HCV vertical transmission and summarizes the updated follow up guidelines for clinical practice.
