[Epidemiological and laboratory observations on viral hepatitis morbidity in child social welfare institutions].

The investigations revealed that in the interval 1978-1987 the mean incidence of viral hepatitis type B in children was 40 at 100,000 inhabitants as compared to 767 in the children from orphanages. In 27.5% of the cases, the children from orphanages, with or without HBs antigen, had viral hepatitis in their case history. The prevalence of AgHBs carriers was of 21.6%, the highest value (46.1%) being recorded in the children from orphanages in the age group 0-3 years. It was also found that 14.9% of the children had AgHBs when admitted to orphanage and 28.7% became carriers later on. It is suggested that in children homes there are conditions for an increased risk requiring special measures for viral hepatitis prophylaxis and control.
