[Certain data concerning the analysis of the foci of infectious hepatitis in cases of subsequent occurrence of the disease in families].
Materials of epidemiological analysis of familial infectious hepatitis nidality in 104 families are presented. The data obtained pointed to the preponderant affection of children constituting 97.1% of primary and 87.7% of subsequent cases in familial foci. Infection was brought to the families by schoolchildren in 57.7% of the cases, and by organized preschoolchildren--in 31.7% of the cases. The greatest affection of schoolchildren aged from 7 to 14 years in the foci with subsequent occurrence of the disease (77.7%) was explained by their marked age activity. This led to the conclusion that mass prophylaxis with alpha-globulin of these particular groups of children was of primary importance. The differences of the specific ratio of adults who contracted the disease in familial foci and in the region as a whole pointed to the possibility of infection of adults outside the family and on the prevalence in them of serum hepatitis.
