Abstract
Hepatitis B virus (HBV) is the leading cause of cirrhosis and hepatocellular carcinoma all over the world. Its prevalence varies greatly from one country to another and reaches 25% in certain parts of Africa and Asia and less than 1% in Europe and America. A variety of risk factors have been found to be responsible for the high prevalence of HBV.
