title: [Various epidemiological principles of the spread of viral hepatitis in the Astrakhan district].
abstract: Analysis of many-year changes in the vitral hepatitis incidence in the Astrakhan region showed a significant cyclicity of the epidemic process: its incidence rose 4 times during the period of from 1957 to 1976; four of these elevations were comparatively high (in 1960, 1964, and 1974). Lately the group of children aged from 3 to 7 years has been of the greatest epidemiological significance, but at present greatest incidence of the disease fell on the group of persons aged from 8 to 14 years. This can be connected with gamma-globulin vaccinations given to children aged under 10 years. Seasonal distribution of morbidity in different are groups was about the same and reflected the general automn-winter seasonal prevalence.
