If a newborn has jaundice, the question of whether the temperature will be high needs to be tailored to the specific situation. First, it is the case that the body temperature will not be high. If the child has jaundice, it is physiological jaundice or neonatal hemolytic jaundice. In this case, the child’s body temperature is normal, and the degree of jaundice in the child varies, relatively speaking, according to the specific situation. In neonatal hemolytic jaundice, the jaundice index is relatively high, while in physiological jaundice the jaundice index is relatively low and the child is in good spirits. Next, there is neonatal jaundice accompanied by an increase in body temperature. In this case, the child’s jaundice is mainly caused by pathological factors, such as viral hepatitis. If the child is infected with hepatitis B virus or cytomegalovirus, the child will not only have jaundice, but also fever. In addition, if the child has sepsis, the child will also develop jaundice and have an elevated temperature.
