Hepatitis B has recently become a prominent figure as one of the major communicable disease in Korea. Many reports on the HBV infection have been accumulated these years, but most of them were clinical and descriptive epidemiologic findings mainly to figure out the characters, size, and pattern of the infection in terms of hepatitis B antigenemia. This study was planned to pursue an analytic study to detect risk factors associated with the hepatitis B infection, successively to our previous study on the risk factors of HBSantigenemia.5) Three hundred and forty one subjects were selected randomly among those who were both HBsAg and HBsAb negative by RPHA and PHA tests at 1984 and have not received hepatitis B vaccination and have not suffered from liver disease since then. Data about the risk factors of HBV infection have been collected by direct interview with structured questionnaire, review of health records and serologic test for HBV markers by RIA methods from July to October, 1986. The results obtained were as follow : 1. The positive conversion rate of HBsAg was 8.5% in adult males and 3.5% in adult females and the total infection rate of HBV was 75.3% and 53.5% respectively. 2. In Korean adults HBV seems to be disseminated partly through the parenteral routes, but mainly through the oral routes, so more attention and energies should be concentrated on the interception of oral routes of HBV infection.
