When a mother with hepatitis B gives birth to a child without immunoglobulin, the child does not necessarily get hepatitis B, but the chances of contracting the hepatitis B virus are much higher than if she had been given immunoglobulin. Whether the newborn will be born infected if the mother has hepatitis B is related to the amount of hepatitis B virus the mother carries. If the mom does not have a high amount of the virus, then the newborn is unlikely to be infected. On the contrary, if the amount of Hepatitis B virus in the mother’s body is very high, then the chances of the newborn being infected will also increase. When a mother with hepatitis B gives birth to a child, it is recommended that she should tell the attending doctor about her health condition in advance, and under the doctor’s guidance, the newborn should be injected with hepatitis B immunoglobulin in a timely manner after the delivery. The albumin can block the entry of hepatitis B virus into the newborn’s body, and the success rate of the blockage reaches more than 95%, which will greatly reduce the likelihood of the newborn’s being infected with hepatitis B.
