Hepatitis B virus is a potentially life-threatening cause of liver disease in the world. It both causes chronic infection and puts people at high risk of death from cirrhosis and liver cancer (1). Globally, it is estimated that more than 2 billion people are still living with HBV infection. Over 350 million are believed to be chronically infected with the virus and are thought to be at a high risk of developing chronic hepatitis, cirrhosis, and primary hepato-cellular carcinoma. About 1.2 million die annually from chronic hepatitis, cirrhosis, and hepatocellular carcinoma (2).
