Not necessarily. Jaundice is a yellowing of the skin and mucous membranes as well as other tissues and body fluids due to an increase in bilirubin in the blood. Clinically, jaundice is generally classified into four types: hepatocellular jaundice, hemolytic jaundice, obstructive jaundice and somatic jaundice. The latter three types are caused by non-hepatitis factors. Hepatocellular jaundice is congenital and acquired, and congenital syndromes such as Gillbert and Rotor are chromosomally inherited and are not caused by hepatitis. There are also acquired jaundice caused by liver cancer and typhoid fever, so it is inaccurate to diagnose hepatitis solely on the basis of jaundice.
