[HBsAg carriers--a study performed on a closed collective of 0- to 3-year-old children].

The clinical, functional-histological and mainly the therapeutical aspect in chronic hepatitis, still raises important problems in children's pathology. As the clinical aspect of the chronic liver diseases is variable and less suggestive in the early and even advanced stages in children, the authors followed--for three years--the incidence of biochemical and histological functional disturbances in a closed collectivity of children. Since no specific therapeutical possibilities exist yet, the importance for a better knowledge of epidemiology of post-viral chronic hepatitis is emphasized.
