Viral hepatitis refers to liver inflammation caused by hepatitis viruses, such as hepatitis A, B, C, D, and E, which lead to liver function impairment. Generally, the liver inflammation caused by these viruses is infectious. Thus, viral hepatitis is treated in the department of infectious diseases. However, if secondary hospitals or other general hospitals do not have such specific subdivisions, patients with viral hepatitis can also visit the department of gastroenterology. Currently, many infectious diseases departments are also called departments of contagion. It is one and the same department, and if there is no department of infectious diseases, one must visit either the department of contagion or gastroenterology for treatment.
