B형 만성 간질환 환자 자녀들의 B형 간염 바이러스 감염률-특히 0-19세 자녀들의 감염률-

초록

Backgrounds/ Aims: This study aimed to estimate the seroepidemiology of hepatitis B virus (HBV) infection with emphasis on the transmission of HBV infection between mothers and their children. Methods: For 452 patients with HBV associated chronic liver disease, and 1,098 of their offspring, who visited Korea University Kuro Hospital from February, 2000 to February, 2001, HBsAg was tested by radioimmunoassay. Results : Among siblings whose mothers were HBsAg-positive, the overall prevalence rate of HBV infection was 44.9% (140/312) and decreased with decreasing age (54.7% in ≥20 years old age group, 33.3% in 10- 19 years old age group, 7.6% in <10 years old age group). The estimated proportion of perinatal infection out of modes of HBV transmissions in the general population was 38% in <10 years and 63.4% in 10- 19 years. Conclusion: The present hepatitis B vaccination strategies - especially against perinatal infection- of Korea have performed to their utmost. More effective methods for the prevention of HBV transmission are now needed.
