Hepatitis Hepatitis is caused by viruses, hepatitis A, B, and C, which inflame the liver, preventing it from its normal function. Symptoms of hepatitis A and B include lack of energy and appetite. Some time after the initial exposure Hepatitis C usually leads to mild symptoms. However, most of the affected people develop chronic liver disease later in life. There are vaccines for Hepatitis A and B. Intensive research is now under way looking for a vaccine for hepatitis C. Hepatitis requires no treatment.
People recover after rest.
Hepatitis B and C can be treated with a substance called interferon. For more information about hepatitis C, contact the American Liver Foundation .
