Inflammation of the liver which may be caused by one of five hepatitis viruses: A, B, C, D, or E. Whereas A and E are food-borne, the other types are transmitted through contaminated body fluids. Hepatitis B and C can both lead to chronic illness and are the main cause of cirrhosis and cancer of the liver. An acute hepatitis infection can lead to characteristic jaundice, where the skin and mucous membranes turn yellow. Other symptoms include nausea, fever, fatigue, and muscle aches. Vaccines only exist against hepatitis A and B.
