Neonatal jaundice is classified into physiological and pathological, and is not usually associated with the mother having hepatitis B. Pathological jaundice is mostly associated with hemolysis of the newborn, preterm delivery, asphyxia, and so on. Neonatal jaundice is the yellowing of the skin or organs caused by the accumulation of bilirubin in the body, which is a common disease in newborns. It is usually divided into physiologic and pathologic. Physiologic jaundice is caused by a temporary increase in serum bilirubin, which may subside after a period of time. It is not related to the mother’s hepatitis B. Pathological jaundice is often caused by neonatal hemolysis, prematurity, asphyxia, infection and other pathological factors, and usually has no obvious correlation with the mother having hepatitis B. Hepatitis B virus can be transmitted from mother to child, and there are usually no obvious symptoms after infection. It is recommended to consult a doctor to identify the specific cause of jaundice.
