摘要
目的分析2020-2021年云南省食源性沙门氏菌感染腹泻的流行病学特征,为食源性疾病的防治提供理论依据。方法收集2020年1月至2021年12月云南省医疗机构上报的食源性疾病个案病例监测数据,应用描述性流行病学方法对病例个案的患者性别、年龄、发病时间、可疑食品暴露史、食品加工及包装方式、进食场所、临床症状、初步诊断、血清型分型等指标进行统计分析。结果本研究共收集9060例食源性疾病腹泻病例,检出沙门氏菌感染者452例。阳性检出率4.99%,男性、女性检出率分别为5.57%、4.33%;以0~5岁年龄组检出率最高(7.84%)。不同月份沙门氏菌检出率差异有统计学意义(χ^(2)=127.004,P<0.05),以7月检出率最高(8.67%);可疑食品暴露史以婴幼儿食品为主,病例检出率最高为7.95%;不同食品加工及包装方式以散装食品为主,病例检出率最高(6.04%),其次为家庭自制食品(5.71%)。家庭是沙门氏菌感染的主要场所,病例检出率为5.53%。沙门氏菌感染者大便性状以水样便为主(61.50%),初步诊断急性胃肠炎占比最多(46.02%),其次为感染性腹泻(37.83%)。沙门氏菌血清型共检出34个,以鼠伤寒沙门氏菌(18.36%)、鼠伤寒沙门氏菌变种(13.72%)等为主。结论云南省沙门氏菌感染引起的食源性疾病较为普遍,应加强监测,对及时发现食品安全隐患和减少食源性疾病的发生有重要意义,也将为食品安全监管提供科学依据。
The aim of this study was to analyze the epidemiological characteristics of diarrhea due to food-borne Salmonella infection in Yunnan Province from 2020 to 2021,to provide a theoretical basis for the prevention and treatment of food-borne diseases.Surveillance data of food-borne disease cases reported by medical institutions in Yunnan Province from January 2020 to December 2021 were collected.Descriptive epidemiological methods were used to analyze the sex,age,onset time,suspicious food exposure history,food processing and packaging,eating place,clinical symptoms,preliminary diagnosis,serotype and other indicators among cases.A total of 9060 cases of food-borne diarrhea were collected,and 452 cases of Salmonella infection were detected.The positivity rate was 4.99%,(5.57%and 4.33%in males and females,respectively).The highest detection rate was found in the 0-5 year age group(7.84%).The detection rate of Salmonella significantly differed by month(χ^(2)=127.004,P<0.001),and the highest detection rate was in July(8.67%).Most cases with a history of suspected food exposure involved food for infants and young children;the highest case detection rate was 7.95%.The primary food processing and packaging methods involved bulk food,which had the highest case detection rate(6.04%),and was followed by home-made food(5.71%).The home was the main site of Salmonella infection.The main stool characteristic among Salmonella infected people was watery stool(61.50%).The primary diagnosis was acute gastroenteritis(46.02%),which was followed by infectious diarrhea(37.83%).A total of 34 Salmonella serotypes were detected,mainly Salmonella Typhimurium(18.36%)and Salmonella Typhimurium variants(13.72%).Food-borne diseases caused by salmonella infection are relatively common in Yunnan Province;therefore,strengthening of monitoring is essential for timely detection of food safety risks and decreasing the occurrence of food-borne diseases,and for providing a scientific basis for food safety efforts.
