摘　　要：目的 分析2017—2021年四川省其他感染性腹泻病例的流行病学及病原学特征,为疾病防控提供科学依据。方法 收集中国疾病预防控制信息系统传染病监测系统中2017—2021年四川省报告的其他感染性腹泻病例相关资料,采用描述性流行病学方法进行分析。结果 2017—2021年四川省累计报告其他感染性腹泻病例210 677例,年均报告发病率为50.60/10万,年报告发病率为42.87/10万~67.71/10万,报告发病率总体呈上升趋势(χ^(2)_(趋势)=4 926.705,P<0.001)。男性和女性报告病例数分别为113 661例和97 016例,年均报告发病率分别为53.49/10万和46.76/10万;各年龄组人群中,2岁以下幼儿报告病例数最多,占病例总数的51.52%(108 537/210 677);各职业人群中,散居儿童报告病例数最多,占病例总数的63.15%(133 037/210 677)。四川省其他感染性腹泻呈现冬季和夏季两个发病高峰,12月—次年1月为冬季高峰,7—9月为夏季高峰。四川省21个市(州)均有报告病例,各市(州)年均报告发病率为22.60/10万~70.16/10万。明确病原诊断的病例22 541例,其中,病毒性腹泻病例20 901例,细菌性腹泻病例1 625例,真菌性腹泻病例15例。病毒性腹泻病例中,轮状病毒感染占88.64%(18 526/20 901)。2017—2021年四川省共报告暴发疫情20起,其中19起为诺如病毒感染,1起为轮状病毒和诺如病毒合并感染。结论 四川省其他感染性腹泻报告发病率呈逐年上升趋势,2岁以下散居儿童是防控重点人群,轮状病毒是主要病原体。应积极关注并加强对其他感染性腹泻的监测和防控。Objective To analyze the epidemic characteristics and the pathogen of other infectious diarrhea in Sichuan Province from 2017 to 2021 for scientific basis for epidemic prevention and control of the infection. Methods The data on the reported cases of other infectious diarrhea for Sichuan Province were collected through the Infectious Disease Surveillance System under the Chinese Disease Prevention and Control Information System from 2017 to 2021, and analyzed using descriptive epidemiology. Results In total, 210 677 cases of other infectious diarrhea were reported in Sichuan Province from 2017 to 2021, with an average annual reported incidence of 50.60/100 000. The annual reported incidence rate was between 42.87/100 000 and 67.71/100 000, and the reported incidence rate showed an overall upward trend(χ^(2)_(trend)=4 926.705, P<0.001). The number of cases reported was 113 661 for men and 97 016 for women, and the average annual reported incidence was 53.49/100 000 and 46.76/100 000, respectively. For all age groups, children under 2 years old were most reported, accounting for 51.52% of the total cases(108 537/210 677). By different occupational group, the number of cases was the largest in children living in diaspora, accounting for 63.15% of the total cases(133 037/210 677). Other infectious diarrhea peaked in winter and in summer in Sichuan Province, with climax from July to September and from December to January of the next year. The infections were reported in all 21 cities(prefectures) in Sichuan Province. Average annual reported incidence was between 22.60/100 000 and 70.16/100 000 for each city(prefecture). There were 22 541 cases with definite etiological diagnosis, including 20 901 cases of viral diarrhea, 1 625 of bacterial diarrhea and 15 of fungal diarrhea. In the cases of viral diarrhea, rotavirus infection accounted for 88.64%(18 526/20 901). A total of 20 outbreaks were reported in Sichuan Province from 2017 to 2021, in which 19 cases were associated with norovirus infection and 1 with rotavirus
