[Research status and strategies of preventing mother-to-child transmission of hepatitis B].

Mother-to-child transmission (MTCT) is the main way to transmit hepatitis B virus (HBV), and it is also the biggest contributor to high prevalence of hepatitis B in high endemic areas. Therefore, preventing MTCT may result in the decline of HBV positive ratio foundationally. Hepatitis B vaccination is currently recognized as the most economic, effective and safe measure to prevent MTCT. The key strategies in the future to prevent MTCT should be to enhance the screening of hepatitis B surface antigen, to provide the infants born to surface antigen positive mother with hepatitis B vaccine combine with hepatitis B immunoglobulin(HBIG), and to monitor the effect of the intervention.
