World Health Organization Breast milk is classified as a safe food with the lowest level and risk of hepatitis B. WHO clearly states that there is no evidence that breastfeeding by hepatitis B mothers increases the chance of infection in their infants and recommends breastfeeding for all hepatitis B mothers. CDC Even before the introduction of hepatitis B vaccine, breastfeeding was not reported to transmit HBV, and breastfeeding does not need to be delayed until after full immunization with hepatitis B vaccine. Domestic studies and guidelines: China’s Guidelines for the Prevention and Treatment of Chronic Hepatitis B Newborns may receive breastfeeding from HBsAg-positive mothers after hepatitis B immune globulin (HBIG) and hepatitis B vaccine are administered within 12 hours of birth. Clinical Guidelines for the Prevention of Mother-to-child Transmission of Hepatitis B Virus (1st Edition) (2013) Although HBsAg and HBV DNA can be detected in the milk of HBV-infected pregnant women, and it has been suggested that cracked nipples, excessive sucking or even biting of the nipples by infants may transmit the virus to infants, these are theoretical analyses and lack evidence-based medical evidence. Even without immunoprophylaxis, the infection rate of breastfed and artificially fed newborns is almost the same. More evidence proves that breastfeeding does not increase the risk of infection even if the pregnant woman is HBeAg positive. Therefore, after formal prophylaxis, regardless of whether a pregnant woman is HBeAg positive or negative, her newborn can be breastfed without testing for the presence of HBV DNA in the milk. Example of a large sample study showed that 244 cases (4.32%) of infants born to hepatitis B mothers developed hepatitis B infection after receiving routine hepatitis B vaccine immunization. Among them, 2717 cases were breastfed, 114 cases were infected, with an incidence of 4.2%. 2933 cases were artificially fed, 130 cases were infected, with an incidence of 4.4%. The results suggest that the incidence of hepatitis B infection in breastfed and artificially fed infants is comparable. Because hepatitis B infection mostly occurs in utero or at delivery, breastfeeding does not increase the risk of hepatitis B infection in infants. Conclusion: Breast milk is the best food for infants, and breastfeeding has the irreplaceable superiority of artificial feeding. Hepatitis B is a blood-borne disease and it is not possible to transmit the hepatitis B virus through the digestive tract. Please uphold the basic rights of infants.
