The possibility of the retrospective epidemiological diagnosis of viral hepatitis non A, non B with the fecal-oral mechanism of the transfer of infection in three cities of Central Asia on the basis of the analysis of the dynamics of registered hepatitis A morbidity is shown. With the irregularity of morbidity levels among the total population being characteristic of all three cities, in Andizhan one rise in morbidity within a period of 3 years (1975-1978) and in Tashauz one rise within a period of 5 years (1975-1980) were registered. The analysis of the dynamics of morbidity observed in individual age and social groups showed that these rises, especially those registered in 1976 in Andizhan and in 1977 in Tashauz, were determined by morbidity levels among school children and adults. This is also true for a rise in morbidity rate registered in Tashauz in 1985. In Andizhan the highest morbidity rates among adults were registered in districts insufficiently equipped with modern amenities. Cases of infection registered as hepatitis A (HA) among persons immune to HA at territories with high intensity of the epidemic process of HA at the above-mentioned periods seem to be due to viral hepatitis non A, non B with the fecal-oral mechanism of the transmission of the infective agent.
通过分析甲型肝炎发病率的动态变化，表明在中亚三个城市基于粪 - 口传播机制对非甲非乙型病毒性肝炎进行回顾性流行病学诊断是可能的。所有三个城市的总人口发病率水平都具有不规则性，在安集延，登记到在3年期间（1975 - 1978年）发病率有一次上升，在塔什乌兹，登记到在5年期间（1975 - 1980年）发病率有一次上升。对各个年龄和社会群体中观察到的发病率动态分析表明，这些上升，特别是1976年在安集延和1977年在塔什乌兹登记到的上升，是由学龄儿童和成年人中的发病率水平决定的。1985年在塔什乌兹登记到的发病率上升情况也是如此。在安集延，成年人中发病率最高的情况出现在现代设施配备不足的地区。在上述时期甲型肝炎流行强度高的地区，在对甲型肝炎免疫的人群中登记为甲型肝炎（HA）的感染病例似乎是由具有粪 - 口传播机制的非甲非乙型病毒性肝炎引起的。
