Hepatitis B minor triyang in pregnant women may affect their children, most notably because there is a risk of transmission of the virus to the child. Hepatitis B minor triple positive refers to the serum marker indicators of the patient’s test for hepatitis B two-to-half, presenting as negative for E antigen, positive for E antibody, positive for surface antigen, and positive for core antibody. In the case of hepatitis B minor triple positive in pregnant women, the probability of hepatitis B virus transmission to the child is relatively low, but it is not completely free of contagion. When the patient has a high viral load, routine mother-to-child blockade should be performed. Specific measures are mainly a combination of mother-to-child blockade during pregnancy and postpartum mother-to-child blockade. The mother mainly follows the doctor’s instructions to take antiviral drugs, such as tenofovir, as well as newborns timely injection of hepatitis B vaccine and hepatitis B immune globulin. After pregnancy, patients with hepatitis B minor triple yang must go to the hospital regularly for review. If the condition is found to be aggravated, it must be actively treated.
