HEPATITIS: TYPES, TRANSMISSION, PATHOGENESIS, TREATMENT, AND PREVENTION

Abstract

Hepatitis is an inflammatory disease of the liver primarily caused by viral infections, though autoimmune disorders, toxins, and metabolic conditions may also contribute. Viral hepatitis remains a major global health problem due to its high prevalence and potential progression to chronic liver disease, cirrhosis, and hepatocellular carcinoma. This paper reviews the major types of viral hepatitis, routes of transmission, pathogenesis, clinical features, diagnostic approaches, treatment options, and preventive strategies.
