B 형 간염 환자에서의 Delta agent 의 감염상

Delta agent is known to be highly infectious to HBV carriers. Despite of the high prevalence of HBV infection in Korea, only few studies of delta infection has been reported and its results are different from foreign study. Therefore authors evaluated the prevalence of delta infection by the sera from 40 HBsAg positive patients with various liver diseases, who consist of 15 patients with chronic active hepatitis, 10 with chronic persistent hepatitis, 3 with liver cirrhosis, 3 with hepatocellular carcinoma and 9 with acute viral hepatitis. Following results were obtained: 1) Anti-delta was detected in only 1 case of 40 cases. 2) It is suggested that delta infection is still rare in Korea despite of high endemicity of HBV infection.
