As far as I can see, the latest guidelines worldwide recommend that regardless of hepatitis B viral load, hepatitis attack or not, as long as the child is born with regular co-immune blockade, breastfeeding is allowed without artificial feeding. The follow-up results of our hospital found that breastfeeding is safe in case of low maternal viral load and there was no case of transmission to the child. However, maternal breastfeeding with high viral load is still infectious to the child, although the risk is not very high. Therefore, I recommend that mothers with low viral load can breastfeed. High viral load mothers need to carefully consider the risk of breastfeeding, especially if there is a broken nipple, bleeding, or a broken mucosa in the newborn’s digestive tract should temporarily stop breastfeeding and still continue to breastfeed after the nipple damage has healed. If you choose to breastfeed, you should pay close attention to the baby’s oral and digestive tract. If you find that the baby has thrush, mouth ulcers, oral herpes or gastrointestinal discomfort such as diarrhea, you should suspend breastfeeding and continue to breastfeed after it is cured. Breastfeeding also increases postpartum contact between mother and baby. Due attention should also be paid to this process. Wash your hands before breastfeeding and gently wipe your nipples with a warm, clean towel before feeding your child. The child’s and mother’s supplies should be separated, and towels and basins for scrubbing and water cups for drinking should be used independently. The liver function should be checked regularly during breastfeeding so that the immune system does not change and breastfeeding makes the condition worse. In addition, we have found that many women with high viral load who are artificially fed often chew food and then feed it to their children, so that the hepatitis B virus is directly ingested by the children through their saliva, and the children are negative for hepatitis B surface antigen when they are 6 months old, but they become positive at 12 months, and some of them have a high viral load. Therefore, it is strongly recommended that pregnant women with hepatitis B do not chew food and feed it to their children.
