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.
对阿斯特拉罕地区病毒性肝炎发病率多年变化的分析表明，流行过程具有明显的周期性：1957年至1976年期间其发病率上升了4倍；其中四次升高幅度相对较大（分别在1960年、1964年和1974年）。最近，3至7岁儿童组具有最大的流行病学意义，但目前该病发病率最高的是8至14岁人群。这可能与对10岁以下儿童进行的丙种球蛋白疫苗接种有关。不同年龄组发病率的季节分布大致相同，反映了秋冬季普遍高发的情况。
