摘　　要：目的了解重庆市儿童群体中食源性疾病流行病学特征及病原体检出情况,为预防儿童感染性腹泻提供科学依据。方法以2019-2021年重庆医科大学附属儿童医院采集的食源性疾病病例粪便标本进行沙门氏菌、副溶血性弧菌、志贺氏菌、致泻大肠埃希氏菌及诺如病毒的病原学检测,并对结果进行分析。结果2019-2021年共报告438例病例,采集标本354件,有126份标本检出阳性,检出率为35.59%,病原体检出情况为沙门氏菌103株(29.10%),致泻大肠埃希氏菌3株(0.85%),诺如病毒33株(9.32%),未分离出志贺氏菌和副溶血性弧菌,致病菌合并诺如病毒感染13例(3.67%);病例主要集中在小于或等于5岁年龄段,阳性标本多集中在小于或等于2岁年龄段,占阳性标本总数的82.08%(食源性致病菌)和84.85%(诺如病毒);可疑食品大部分来自家庭自制食品,占所有病例的71.92%。结论重庆地区儿童食源性疾病病原体以沙门氏菌和诺如病毒为主,应有针对性地加强食品安全宣教健康教育,开展食源性疾病防控知识宣传,以降低食源性疾病的发生。Objective To investigate the epidemiological characteristics and pathogen detection results of food-borne diseases among children in Chongqing,and to provide scientific basis for the prevention of infectious diarrhea in children.Methods From 2019 to 2021,fecal samples of food-borne diseases collected by Children′s Hospital of Chongqing Medical University were detected for Salmonella,Vibrio parahaemolyticus,Shigella,diarrhea Escherichia coli and Norovirus,and the results were analyzed.Results From 2019 to 2021,a total of 438 cases of food-borne diseases were reported and 126 positive samples were detected from a total of 354 feces samples,with a detection rate of 35.59%.The pathogens were 103 strains of Salmonella(29.10%),three strains of diarrhea Escherichia coli(0.85%),33 strains of Norovirus(9.32%),no Shigella and Vibrio parahaemolyticus were isolated,and 13 cases of pathogenic bacteria combined with Norovirus infection(3.67%).The cases were mainly concentrated in the age group less than or equal to five years old,and the positive samples were mostly concentrated in the age group less than or equal to two years old,accounting for 82.08%(food-borne pathogens)and 84.85%(Norovirus)of the total positive samples.Most of the suspected food came from home-made food,accounting for 71.92%of all cases.Conclusion Salmonella and Norovirus are the main pathogens of food-borne diseases among children in Chongqing.So food safety education and health education should be strengthened,and food-borne disease prevention and control knowledge should be publicized to reduce the occurrence of food-borne diseases.
