某儿童医院10年临床报告细菌性痢疾的流行病学特征

目的探讨细菌性痢疾(以下简称菌痢)近10年流行特点。方法对10年来收集的全院各科上报的菌痢进行回顾性分析。结果1993-2002年报告菌痢10861例,占传染病报告总数的62.92%,传染科门诊量占全院门诊百分比的年变化为8.54%～4.33%;菌痢发病占传染科门诊的年比率变化为1.05%～3.45%;<1岁、1～3岁、4～6岁、7～9岁、≥10岁5个年龄组,各组之间菌痢检出率差异有统计学意义,1～3岁组检出率最高;细菌性痢疾每年4月检出率开始上升,8月达最高,11月检出率恢复到上升前水平;不同性别的儿童检出率差异有统计学意义,男童明显高于女童。结论细菌性痢疾检出年龄特点为婴幼儿最高,随年龄增长,发病逐渐减少;发病高峰季节向春秋季扩展。

Epidemiological Characteristics of Bacillary Dysentery in One Children's Hospital From 1993 to 2002

Objective To find out the epidemic characteristics of bacillary dysentery form 1993 to 2002. Methods The reported data of bacillary dysentery in the hospital from 1993 to 2002 were analyzed retrospectively. Results 10 861 bacillary dysentery cases had been reported form 1993 to 2002, which accounted for 62.92% of all reported infectious disease cases in the hospital during the ten years. The annual proportion of the volume of infectious disease outpatients to the total volume of outpatients of the hospital went down form 8.54% to 4.33%, but the annual proportion of the volume of bacillary dysentery outpatients to the total volume of infectious disease outpatients went up from 1.05% to 3.45%. There was a significant difference in the detection rate of bacillary dysentery between the five age groups of less than 1 year old,1 to 3 years old,4 to 6 years old,7 to 9 years old and 10 years old and older. The detection rate of 1 to 3 years old was the highest. The detection rate of bacillary dysentery began to go up from April, reached the highest in August, went down thereafter, recovered normal level in November. The detection rate of bacillary dysentery among boys was significantly higher than that among girls. Conclusions The detection rate of bacillary dysentery among infants is the highest and it becomes lower as older.The season of incidence peak of bacillary dysentery expands from summer to spring and autumn.
