Usually, if the father has the hepatitis B virus, it will not be transmitted to the child. Hepatitis B is mainly transmitted from mother to child. Usually, if the father carries the virus and the mother is normal, the chances of the child being infected with hepatitis B are very low; if the mother has the hepatitis B virus, the viral load is very high and it is possible that the virus will be infected during the birth process and close contact. Therefore, if the father has the hepatitis B virus, it is usually not transmitted to the next generation. If the father has hepatitis B surface antigen, the fetus should be given hepatitis B vaccination in a timely manner after birth in accordance with the process to monitor the infant’s hepatitis B surface antibody, thus reducing the possibility of transmitting the virus to the child during close contact in the future.
