Hello, mother-to-child transmission of hepatitis B can occur during delivery and around the time before and after birth. Hepatitis B virus is present in amniotic fluid, vaginal secretions, blood, sweat, and breast milk, as well as saliva, and can be transmitted to the fetus or infant during delivery. Before delivery, the fetus can be directly infected in the uterus through the placenta, although this is uncommon and accounts for about 5% to 10% of cases. More commonly, infection occurs during delivery through contact with maternal blood or amniotic fluid, or through close contact after birth.Medical Advice: Within 12 hours after the infant's birth, an intramuscular injection of hepatitis B immune globulin should be administered. The first dose of hepatitis B vaccine should be given 1 to 2 weeks later, followed by the second and third doses one month and six months after the first vaccination, respectively. This approach can prevent mother-to-child transmission in over 90% of children born to hepatitis B carriers.
Lifestyle Care: Additionally, after delivery, breastfeeding should be avoided, and kissing infants or young children, sharing utensils, towels, and other personal items should be avoided.
