Hepatitis B is a worldwide healthcare problem, especially in developing areas. An estimated one third of the global population is infected with the hepatitis B virus (HBV). Approximately 350-400 million people have lifelong chronic infection, and 0.5 % spontaneously seroconvert annually from having the hepatitis B surface antigen (HBsAg) to having the hepatitis B surface antibody (anti-HBs).
