title: [An attempt to estimate epidemiologic prevalence of HBs associated antigen among hospitalized children].
abstract: We have observed the problem of the more frequent occurrence of the hepatitis-associated antigen (HBsAg) among multiple hospitalized children and we have analysed the medical documentation of children who were treated in the Department of Gastroenterology and Pediatrics of the Medical Academy of Bydgoszcz in 1989-1992 years. In this period of time we have recorded 39 children with HBsAg. In 80% (31 patients) there are children, who were hospitalized two or more times. We have proved, that in the group of children with HBsAg, children with chronic illness or frequently hospitalized were the risk group.
