Viral hepatitis is caused by various viruses, primarily affecting the liver and characterized as an infectious disease. Clinically, the main symptoms include loss of appetite, nausea, abdominal discomfort, pain in the liver area, and fatigue. Some patients may also experience jaundice and fever. Common causes include five types of hepatitis viruses: Type A, B, C, D, and E. Generally, hepatitis B and C can lead to chronic hepatitis. Acute hepatitis is primarily treated symptomatically, while chronic conditions like hepatitis B and C usually require antiviral treatment.
