摘　　要：目的分析2013—2022年岳池县其他感染性腹泻的流行特征及其病原学检测结果,以便科学精准地开展防控工作。方法通过中国疾病预防控制信息系统收集2013—2022年岳池县其他感染性腹泻的发病数据和病原学信息,采用描述性流行病学方法进行分析,利用Excel 2007和SPSS 26.0软件进行数据统计,构成比和率的比较选用χ^(2)检验。结果2013—2022年岳池县其他感染性腹泻报告病例数2851例,年报告发病率24.86~78.09/10万,年均发病率为37.83/10万,发病水平整体呈波动上升趋势。每月均有病例报告,全年2个发病高峰分别为5至6月、11月至次年1月。男女性别比为1.26∶1,男女性年均发病率差异有统计学意义(χ^(2)=12.32,P<0.001)。发病主要集中在3岁以下幼儿,占发病总数的69.59%(1984/2851),以散居儿童为主,发病占比为77.38%(2206/2851)。岳池县所有街道和乡镇均有病例报告,城区年均发病率(46.82/10万)高于乡镇(32.32/10万)(χ^(2)=99.08,P<0.001)。报告的病例中有明确病原学诊断的占12.56%(358/2851),其中轮状病毒感染占84.36%(302/358)。报告聚集性疫情2起,均由诺如病毒感染引起。结论岳池县其他感染性腹泻整体发病水平呈波动上升趋势,初夏和冬季高发,3岁以下散居儿童为重点风险人群。确诊病例以轮状病毒感染为主,聚集性疫情皆由诺如病毒引起。针对以上流行特征,应加强散居儿童看护人的肠道传染病健康宣教,加强各级医疗机构肠道传染病相关病原检测能力的培训,在流行高峰季加强对托幼机构和学校等重点场所的防控督导。Objective To analyze the epidemiological characteristics and pathogenic test results of other infectious diarrhea in Yuechi County from 2013 to 2022,in order to scientifically and accurately carry out prevention and control work.Methods Incidence data and pathogenic information of other infectious diarrhea in Yuechi County from 2013 to 2022 were collected through the China Disease Prevention and Control Information System.Descriptive statistics were performed,and Excel 2007and SPSS 26.0 software were used.Chi-square test was used to compare the composition ratio and rate.Results From 2013 to 2022,2851 cases of other infectious diarrhea were reported in Yuechi County.The annual reported incidence was 24.86/105-78.09/105,and the annual average incidence was 37.83/105.The overall incidence was fluctuating.There are cases reported in every month,and the two peaks of incidence throughout the year are from May to June and from November to January of the next year.The sex ratio of men to women was 1.26∶1,and there was a statistically significant difference in the annual average incidence between men and women(χ^(2)=12.32,P<0.001).The incidence of the disease is mainly concentrated in children under 3 years,accounting for 69.59%of the total cases(1984/2851),Especially,most cases were scattered children,accounting for 77.38%(2206/2851)of the total cases.Cases have been reported in all streets and towns in Yuechi County.The average annual incidence in urban areas(46.82/105)is higher than that in towns(32.32/100000),with a statistically significant difference(χ^(2)=99.08,P<0.001).Among the reported cases,12.56%(358/2851)had a clear pathogenic diagnosis.Specifically,84.36%(302/358)were infected with rotavirus.Two clustered outbreaks were reported,both caused by Norovirus infection.Conclusions The overall incidence of other infectious diarrhea in Yuechi County shows a fluctuating upward trend,with high incidence in early summer and winter.Scattered children under the age of 3 were the key risk population.The confirmed cas
