Doctor's answer:

According to the summary, if the mother has a small triangle hepatitis B, 40% of newborns will suffer from hepatitis B; if the mother has a large triangle hepatitis B, 90-95% of newborns will suffer from hepatitis B. However, prevention work can be done. The following preventive measures can be taken:
1. Cesarean section, no breastfeeding, postpartum anesthesia for newborns with hepatitis B vaccine 0, 1, 6 months, 30mg each time, 70% can prevent it.
2. During the early pregnancy of the 7th, 8th, and 9th months, administer 200 units of anti-hepatitis B immune globulin monthly. After the newborn is delivered, administer 100 units of hepatitis B immune globulin to the outer side of the thigh. Repeat 100 units after 20 days, and then vaccinate with hepatitis B vaccine 30, 10, 10mg at 1, 2, and 7 months, respectively, 95% can prevent it.
