2006—2015年新疆生产建设兵团细菌性痢疾流行特征分析

Analysis on the epidemiological characteristics of bacillary dysentery in Xinjiang Production and Construction Corps from 2006 to 2015

目的分析新疆生产建设兵团(新疆兵团)2006—2015年细菌性痢疾流行特征,为制定防控策略提供依据。方法对新疆兵团2006—2015年疾病监测报告信息系统报告的细菌性痢疾病例信息进行描述性流行病学分析。结果 2006—2015年新疆兵团共报告细菌性痢疾病例12 380例,年均发病率为47.34/10万,呈现逐年下降趋势(P<0.05),高于同期全国22.89/10万的年均发病率,与新疆维吾尔自治区46.65/10万的年均发病率差异无统计学意义(P>0.05)。北疆各师细菌性痢疾年均发病率为55.75/10万,高于南疆各师的25.97/10万,差异有统计学意义(P<0.05)。发病集中在夏秋季,在7—9月达到高峰。男性发病率明显高于女性(P<0.05)。各年龄组均有发病,0~4岁儿童发病率最高,其次为>80岁人群。发病数最高的职业为散居儿童。结论新疆兵团细菌性痢疾防控形势依然严峻,应在高发团场的重点人群中采取针对性防控措施,有效降低发病水平。

Objective To analyze the epidemiological characteristics of bacillary dysentery in Xinjiang Production and Construction Corps from 2006 to 2015 and to provide scientific evidences for the control and prevention of bacillary dysentery. Methods Descriptive epidemiology was used to analyze the data from routine report system for infectious disease in Xinjiang Production and Construction Corps from 2006 to 2015. Results A total of 12 380 bacillary dysentery cases were reported in the Xinjiang Production and Construction Corps from 2005 to 2016, the annual average incidence was 47.34/105 and displayed a descending tendency （P 〈 0.05）. The incidence was higher than the annual average incidence in China （22.89/105）, and showed no significant difference compared with the annual average incidence in Xinjiang Uygur Autonomous Region （46.65/105） （P 〉 0.05）. Furthermore, the annual average incidence of bacillary dysentery in north Xinjiang （55.75/105） was significantly higher than that in south Xinjiang （25.97/105） （P 〈 0.05）. The incidence was higher in summer and autumn, and reached the peak from July to September. The incidence of males was obviously higher than that of females （P 〈 0.05）. All age groups were affected by bacillary dysentery, but the incidence was highest in 0-4 years group, followed by above 80 years group. Scattered children patients had the highest incidence among all occupations, Conclusiorts The control and prevention of bacillary dysentery in the Xinjiang Production and Construction Corp should not be ignored. Control measures focusing on the target population should be taken in the high-incidence areas, thus effectively reducing the incidence.
