四川省１９５０～１９９６年累计发生细菌性痢疾５０４７８２０例，死亡１７８９８例，发病率波动在１２．０１～４５１．１８／１０万之间，平均年发病率为１２４．９４／１０万，经游程检验，４７年间发病率总的升降趋势不具有统计学意义。病死率波动在０．０５～１．９０％之间；７８．２８％的病例发生在７～１０月；发病最高年龄组为０～４岁，发病专率为４９６．４８／１０万，次为２０～２４岁为２６５．６２／１０万，最低是１０～１４岁仅为４５．２６／１０万；山区发病高于平原及丘陵地区；发病农民占４０．１１％，其次是儿童占２６．７４％。对检出的１０１６９株志贺氏菌菌群分析，Ａ群占３．２％，Ｂ群占８１．３％、Ｃ群占１．７％、Ｄ群占１３．８％，在Ｂ群中，以２ａ血清型占２２％，３血清型占１０％，１ｂ血清型占８％，而福氏３型由５０年代的３４．１％逐年代降至现今的１０％。对流行因素及防治策略作了初步分析和探讨，于今后预防和控制菌痢的发生和流行有参考意义。
In Sichuan province from 1950 to 1996, there were 5047820 cases of bacterial dysentery and 17898 deaths. The incidence fluctuated between 12.01 and 451.18 / 100 000 with an average annual incidence of 124.94 / The overall trend of increase and decrease of incidence in 47 years did not reach statistical significance. The case fatality rate fluctuated between 0.05 and 1.90%. 78.28% of cases occurred between July and October. The highest age group was 0-4 years old and the incidence rate was 496.48 per 100 000. 265.62 / 100000 for 20-24 years old, and the lowest was 45.26 / 100,000 for 10-14 years old. The incidence in mountain area was higher than that in plain and hilly area. The incidence of peasants accounted for 40.11%, followed by that of children 26 .74%. In the 10169 Shigella strains detected, A group accounted for 3.2%, B group accounted for 81.3%, C group accounted for 1.7%, D group accounted for 13.8% in group B , 2a accounted for 22% of serotypes, 3 serotypes accounted for 10%, 1b serotypes accounted for 8%, while the type 3 from 34.1% in the 1950s to 10% nowadays. Preliminarily analyzed and discussed the epidemic factors and the prevention and cure strategies, and made reference in the future to prevent and control the incidence and prevalence of bacillary dysentery.
