Analysis of Active Surveillance Results of Foodborne Diseases in Guandu District from 2014 to 2023

目的:对官渡区食源性疾病主动监测相关数据进行流行病学分析,旨在了解官渡区重要食源性疾病的流行特征。方法:对满足条件的食源性疾病腹泻病人采集粪便标本并收集相关信息,对粪便样本进行5种特定病原体的检测。结果:2014—2023年官渡区共采集生物样本1 883份,阳性137份,阳性检出率7.28%,检出的病原体以诺如病毒为主,占阳性标本的65.69%,其次为沙门氏菌,占20.44%。12月病原体检出率最高,为16.44%。0~14岁年龄组的病原体检出率最高,占阳性样本的81.02%,职业分布上散居儿童病原体检出率最高,占阳性样本的64.23%,可疑暴露食品中以多种食品为主。结论:官渡区食源性疾病发生具有人群、病原体和时间方面的流行病学特征,主动监测特定病原体检出率较低,以诺如病毒和沙门氏菌为主。

Objective:The epidemiological analysis of the relevant data of active monitoring of foodborne diseases in Guandu district was carried out to understand the epidemiological characteristics of important foodborne diseases in Guandu district.Method:Fecal samples were collected from diarrhea patients who met the conditions and relevant information was collected.Five specific pathogens were detected in fecal samples.Result:A total of 1 883biological samples were collected in Guandu district from 2014 to 2023,of which 137 were positive,with a positive detection rate of 7.28%.Norovirus was the main pathogen detected,accounting for 65.69% of the positive samples,followed by Salmonella,accounting for 20.44%.The highest pathogen detection rate was 16.44% in December.The detection rate of pathogens was the highest in the age group under 15 years old,accounting for 81.02% of the positive samples.The detection rate of scattered children was the highest in the occupational distribution,accounting for 64.23% of the positive samples.Conclusion:The occurrence of foodborne diseases in Guandu district has the epidemiological characteristics of population,pathogen and time.The detection rate of active monitoring of specific pathogens is low,mainly norovirus and Salmonella.
