Hyuk Han Kwon
The infection of hepatitis B virus is prevalent in all over the world, and the acute viral hepatitis type B virus can be converted into chronic hepatitis and again progressed to liver cirrhosis, followed by hepatoma. Therefore, the infection of viral hepatitis type B has been a health problem for all over the world in addition to Korea. The positive rate of HBsAg is different according to the social-economic, life environments, local and immunological state, and gene. Recently exploring of vaccine is contributed to preventive the infection of hepatitis B virus. Especially in Korea, where viral hepatitis type B is epidemic and the prevalence rate of HBsAg among healthy people is higher than that of them in developed country, there is a growing need to study the immunolgic or epidemiologic aspect and preventive measures of HBsAg. The auther detected HBsAg by modifide micro-Ouchterlony double immunodiffusion techniques in 1,231 serum samples of American soldiers who have been residued more than six months in Korea, during the period from May to Nov. 1980. The results are summarized as follows 1. HBsAg was detected in 25 samples among 1,231 samples with the positive rate of 2.03%. 2. The positive rate of HBsAg was higher in female 4.46% (5 samples/112 samples) than that in male 1.79% (20 samples/1,119 samples). 3. The lowest prevalence rate of HBsAg was found in the age group of 20-29 years (1.71%) and the highest (93.23%) was in those above 50 years of age. High positive rate of HBsAg was found in the old age group. 4. The prevalence rate of Anti-HBs was found 0.16% (2 Samples/1,231 Samples).
