目的分析2014-2017年广东省清远市清城区其他感染性腹泻的发病特征,为有效控制其他感染性腹泻的流行提供参考依据。方法从中国疾病预防控制信息系统收集2014-2017年清远市清城区其他感染性腹泻病例资料,并进行描述性流行病学分析,计算发病率及不同分类病例的构成比,率和构成比的比较采用卡方检验,检验水准α=0.05。结果2014-2017年清远市清城区共报告其他感染性腹泻病例8854例,年平均发病率为268.10/10万(8854/330.25万),无死亡病例。其中2014-2017年各年发病率分别为229.02/10万(1760/76.85万)、225.44/10万(1898/84.19万)、220.99/10万(1866/84.44万)和392.83/10万(3330/84.77万)。12~2月发病3671例,占总发病数的41.46%;发病数居前3位的地区洲心、凤城和东城街道的发病人数分别占总发病数的29.44%、19.05%和14.51%;病例男女比例为1.36∶1;5岁以下年龄组占总发病数的66.28%,散居儿童占总发病数的66.04%。轮状病毒感染占确诊病例数的86.65%(1688/1948)。结论2014-2017年清远市清城区其他感染性腹泻发病率处于较高水平,高发时间为12-2月,高发地区为洲心、凤城和东城街道,高发人群为5岁以下及散居儿童,主要病原体为轮状病毒,应针对流行特征情况采取有效措施降低其他感染性腹泻的发病率。

Objective To study and analyze the characteristics of other infectious diarrhea in Qingcheng District,Qingyuan City,Guangdong Province from 2014 to 2017,so as to provide basis for effective control.Methods The data of other infectious diarrhea cases in Qingcheng District from 2014 to 2017 was collected from China Disease Prevention and Control Information System and used to analyze in descriptive epidemiology and calculate the incidence and the proportion of different classification cases.Chi square test was used to compare the rate and composition ratio,the test levelα=0.05.Results From 2014 to 2017,a total of 8854 cases were reported in Qingcheng District,with an annual average incidence of 268.10/100000(8854/3302500),and no deaths was reported.In 2014-2017,the annual incidence was 229.02/100000(1760/768500),225.44/100000(1898/841900),220.99/100000(1866/844400),and 392.83/100000(3330/847700).From December to February,there were 3671 cases were reported,accounting for 41.46%of the total.The top 3 areas with the highest number of cases were Zhouxin(29.44%),Fengcheng(19.05%)and Dongcheng streets(14.51%).The ratio of male and female cases was 1.36∶1,the age group under 5 years old accounted for 66.28%of the total number of cases,and the scattered children accounted for 66.04%of the total number of cases.Rotavirus infected cases accounted for 86.65%(1688/1948)of all confirmed cases.Conclusion From 2014 to 2017,the incidence of other infectious diarrhea in Qingcheng District was at a high level,the incidence was in peak from December to February,the areas with the highest incidence were Zhouxin,Fengcheng and Dongcheng streets,the vulnerable population was children under 5 years old and scattered,and the main pathogen was rotavirus.Given these,effective measures should be taken to reduce the incidence of other infectious diarrhea according to the epidemic characteristics.
