Hepatitis B II and V positive in pregnant women will not be passed on to the fetus, and it is recommended to communicate with the attending physician for details. Positive hepatitis B 2 and 5 refers to positive hepatitis B surface antibody and hepatitis B core antibody, which indicates that the body has been infected with hepatitis B virus in the past, but the body has cleared the virus and produced antibodies. At present, it is not a case of hepatitis B infection and there is no hepatitis B virus in the body, so it will not be transmitted to the fetus. Transmission of hepatitis B from pregnant women to their fetuses usually occurs when pregnant women are in the state of hepatitis B. The results of hepatitis B two-to-one half results will show that they are positive for surface antigen and e antigen, etc. At this time, there is hepatitis B virus in the body of pregnant women, and it may be transmitted to the fetus through mother-to-child transmission. Even if the pregnant woman is infected with hepatitis B virus, there is no need to worry, the pregnant woman can follow the doctor’s instructions for antiviral treatment to reduce the viral load, and after the birth of the fetus can use hepatitis B immunoglobulin to block, which can minimize the probability of infection.
