[Epidemiologic characteristics of hepatitis A morbidity among children from one of the districts of Moscow in 1982-1986].
By the epidemic features, the district under study may be classified as a territory with moderate epidemic activity of hepatitis A (HA). The highest incidence was observed in children of 3-6 years of age. Annually, the seasonal wave in the district was started in school children. As a rule, the first case of the disease in preschool children's institutions (PCI) was due to infection contracted from schoolchildren or from adults. The further spread of the infection in PCI was due to breaks in the sanitary-hygienic regimen or principles of isolation of the quarantine group. When these principles and the sanitary-hygienic regimen were observed, the incidence in foci was limited to 1-3 cases of HA. In instances of late introduction of the infection into PCI with crude breaks in the sanitary-hygienic regimen or principles of isolation of the quarantine group "nonseasonal" (February or April) rises in HA incidence occurred in the district.
