The aim of the study was to determine the prevalence of Hepatitis antigens e.g. Hepatitis B surface antigen (HBsAg), anti-HBsAg Hepatitis A and non A and B in liver diseases and in blood donors, hospital staff, specific population and general population in various countries in the Asian Pacific Region through published data and questionnaires. The study confirmed previous data indicating a high prevalence of Hepatitis B in certain areas of the Asian Pacific region. The problem of chronic hepatitis, non A, non B hepatitis will become clearer with more sensitive assays.
