Abstract

The results of studies indicate that the morbidity rates of dysentery among children attending preschool institutions and children brought up at home converged in recent years. This phenomenon was most pronounced among children of the kindergarten age group. At the same time dysentery caused by Sh. sonnei and Sh. flexnery produced a higher morbidity rate among children attending nursery in comparison with that among children of the same age group brought up at home. Group infections in preschool institutions were caused by Sh. sonnei in 89.1% of cases and by Sh. flexneri in 10.9% of cases. Outbreaks due to the transfer of infection through everyday contacts were observed only in dysentery caused by Sh. sonnei, constituting 71.4% of the total number of dysentery outbreaks.

摘要

研究结果表明，近年来，在学前机构就读的儿童和在家抚养的儿童痢疾发病率趋于一致。这种现象在幼儿园年龄组儿童中最为明显。与此同时，与在家抚养的同年龄组儿童相比，在托儿所就读的儿童中，宋内志贺菌和福氏志贺菌引起的痢疾发病率更高。在学前机构中，89.1%的群体感染由宋内志贺菌引起，10.9%由福氏志贺菌引起。仅在宋内志贺菌引起的痢疾中观察到因日常接触传播感染导致的暴发，占痢疾暴发总数的71.4%。
