However, HBV is not a direct cause of hepatitis B. If there is no damage to the placenta, it will not pass through intrauterine infection. Most mother-to-child transmission occurs during the delivery process and after delivery. Cesarean section may be performed during delivery, which will expose the baby to the mother’s blood and other body fluids. The virus is likely to enter the baby’s body at this time. Transmission during childbirth is also a common way of hepatitis B infection. In addition, the hepatitis B virus may also be transmitted during the close contact between the baby and the mother after birth.
