There are no reports in the literature that the presence of hepatitis B in the father is passed on to the newborn. If the mother carries the hepatitis B virus, the newborn will be transmitted, mainly in the perinatal period. If a pregnant woman is carrying hepatitis B virus, the newborn should be treated with mother-to-child blockade at birth. The mother-to-child blockade treatment consists of hepatitis B vaccine and anti-hepatitis B immunoglobulin, which should be given as early as possible at birth, preferably within 24 hours. Current statistics show that the success rate of mother-to-child blockade treatment for hepatitis B can reach about 95%, while the other 5% may be contracted in the pregnant woman. If a pregnant woman has a high viral load, antiviral drugs, preferably tenofovir, can be administered to the pregnant woman in order to ensure that the newborn is not infected with the hepatitis B virus.
