Symptoms of Neonatal Hepatitis
Hepatitis can occur without any noticeable symptoms. Actually, babies and children are the least likely of all people to show signs and symptoms of this disease. It is seen that generally the older you are, the more likely you are to exhibit symptoms of hepatitis.

In its early stages, hepatitis usually has the following symptoms:
Jaundice (yellowing of the skin and whites of the eyes)
Fever
Malaise or weakness
Muscle ache
Abdominal pain
Nausea and vomiting
Diarrhea

Jaundice is caused by a build-up of a chemical called bilirubin in the baby’s blood and tissues. Bilirubin is normally processed by the liver, but a newborn's liver takes a few days to process it, so statistically about 6 out of 10 newborns have jaundice to varying degrees, although not all cases are due to hepatitis.

Infants or children with hepatitis usually have mild or no symptoms at all. An infant with neonatal hepatitis may be under-weight and not show normal growth, since it is not able to absorb the vitamins and other nutrients required for growth, and may also have an enlarged liver and spleen. If the illness progresses, it may cause dark or "tea-colored" urine; white, light, or "clay-colored" stools; bitter taste in the mouth, etc.
