HBV markers in Chinese in Hong Kong.
A study was carried out on 779 hospital patients in the Orthopaedic and Paediatric Unit of Queen Mary Hospital, Hong Kong. Patients who had no clinical evidence of liver disease, previous history of transfusion with blood or blood products and no major surgery in the past were entered into the study. Markers of previous exposure to Hepatitis B virus (HBV) were HBsAg, anti-HBc and anti-HBs (radioimmunoassay) were done. The results showed that (a) Chinese living in Hong Kong are exposed to HBV infection throughout life (b) horizontal transmission is the dominant mode of transmission and (c) cpronic HBsAg carriers probably do not carry HBV for life but may clear HBs antigenaemia with age.
