If the mother has undergone PMTCT and the viral load is relatively low, breastfeeding can be done after stopping the medication. If the mother’s hepatitis B viral load is still very high, it is recommended that breastfeeding be suspended. Whether or not breastfeeding is possible with hepatitis B teratitis III depends on the actual condition. Mothers with Hepatitis B Triple Positive should have their viral load tested during pregnancy, and if the viral load is high, they need to take antiviral medication under doctor’s supervision. And after the baby is born, the mother should do mother-to-child interruption and hepatitis B vaccination, then breastfeeding can be carried out at a later stage. If the mother has a high viral load and is on antiviral treatment, it is generally recommended that breastfeeding be withheld because there is a certain probability that it will lead to hepatitis B transmission. The decision to breastfeed should be made according to your own situation and should be evaluated by a medical professional. Hepatitis B triple positive mothers should pay attention to breastfeeding hygiene when breastfeeding, and need to clean their nipples regularly to avoid the baby eating unclean things. If the nipple is broken or the baby has mouth ulcers, avoid breastfeeding, otherwise the hepatitis B virus will be transmitted to the baby through the bloodstream.
