摘要
目的 分析2012—2022年江苏省常州市新北区副溶血性弧菌引起的食源性疾病暴发事件,为该类事件处理提供参考依据。方法 收集新北区2012年1月1日—2022年12月31日由副溶血性弧菌引起的食源性疾病暴发事件的相关资料,并进行回顾和分析。描述食源性疾病暴发事件的一般情况,以及副溶血性弧菌引发食源性疾病暴发事件的时间分布、地域分布以及患者人群分布;比较食源性疾病暴发事件的患者临床症状、发生场所分布以及发生原因分布。结果 2012年1月1日—2022年12月31日新北区共上报食源性疾病暴发事件19次,涉及患者数287例;其中由副溶血性弧菌引起的食源性疾病暴发事件发生9次(占47.37%),涉及患者数103例(占35.89%)。由副溶血性弧菌引发的食源性疾病暴发事件均发生在6~10月,其中在9月发生次数最多(5次,占55.56%);副溶血性弧菌引发食源性疾病暴发事件在城区发生3次(占33.33%),在农村地区发生6次(占66.67%);由副溶血性弧菌引起的食源性疾病暴发事件涉及的103例患者中,男性53例(占51.46%),女性50例(占48.54%);在年龄分布中,以45~64岁年龄段患者占比最高(54例,占52.43%);患者职业分布中,居家及待业人员的比例最高(35例,占33.98%);可疑食物分布中,海产品及其制品的比例最高(30例,占29.13%)。副溶血性弧菌引发食源性疾病患者人群中,有腹痛症状91例(88.35%),腹泻95例(92.23%),恶心60例(58.25%),呕吐55例(53.40%);副溶血性弧菌引发食源性疾病患者人群出现腹痛、腹泻、恶心、呕吐的比例显著高于其他病原体引发的食源性疾病患者。副溶血性弧菌引起食源性疾病暴发事件的发生场所中,其他的比例最高(3次,占33.33%);副溶血性弧菌和其他病原体引起食源性疾病暴发事件的场所分布比较差异无统计学意义;副溶血性弧菌引起食源性疾病暴发事件的原因分布中,交叉污染的比例最高(5次,占55.56%);副溶血性弧菌与其他病原体引起食源性疾病暴发事件的发生原因分布比较差异无统计学意义。结论 该区发生的食源性疾病暴发事件中由副溶血性弧菌引发的占比较大,患者以中老年为主,事件发生时间集中在夏季和秋季,肉类和水产品是主要的可疑食物,患者以急性胃肠炎为主要临床表现,引发该类事件的主要原因为交叉感染。
Objective To analyze foodborne disease outbreaks caused by Vibrio parahaemolyticus in Xinbei District of Changzhou City in 2012-2022.Methods The data of foodborne disease outbreaks caused by Vibrio parahemolyticus from January 1,2012 to December 31,2022 in Xinbei District were collected for retrospective analysis.The general circumstances of foodborne disease outbreaks was described,and the time distribution,geographical distribution and patient population distribution of foodborne disease outbreaks caused by Vibrio parahemolyticus were described.The patients'clinical symptoms,distribution of occurrence sites and occurrence causes of foodborne diseases were compared.Results During January 1,2012 to December 31,2022,a total of 19 cases of foodborne disease outbreaks were reported,involving 287 patients,among which there were 9 cases of foodborne disease outbreaks caused by Vibrio paraholyticus(accounting for 47.37%),involving 103 patients(accounting for 35.89%).All the foodborne disease outbreaks caused by Vibrio parahaemolyticus occurred from June to October,and the number of outbreaks was the highest in September(5 times,accounting for 55.56%).Foodborne disease outbreaks caused by Vibrio parahaemolyticus occurred for 3 times(accounting for 33.33%)in urban areas and for 6 times(accounting for 66.67%)in rural areas.Among the 103 patients involved in foodborne disease outbreaks caused by Vibrio paratholyticus,53 patients were male(accounting for 51.46%)and 50 patients were female(accounting for 48.54%).In age distribution,the patients of 45-64 years old accounted for the highest proportion(54 cases,accounting for 52.43%).Among the occupational distribution,the proportion of housework and unemployment was the highest(35 cases,accounting for 33.98%).Among the suspicious food distribution,the proportion of seafood and products was the highest(30 cases,accounting for 29.13%).Among the patients with foodborne diseases caused by Vibrio parahemolyticus,91 cases(88.35%)had abdominal pain,95 cases(92.23%)had diarrhea,60 cases(58.25%)had nausea,and 55 cases(53.40%)had vomiting.The proportion of abdominal pain,diarrhea,nausea and vomiting in patients with foodborne diseases caused by Vibrio parahemolyticus was significantly higher than that in patients with foodborne diseases caused by other pathogens.Among the sites of foodborne disease outbreaks caused by Vibrio parahaemolyticus,the other sites had the highest proportion(3 times,accounting for 33.33%).There was no significant difference in the site distribution of foodborne disease outbreaks caused by Vibrio parahemolyticus and other pathogens.Among the causes of foodborne disease outbreaks caused by Vibrio parahaemolyticus,the proportion of cross contamination was the highest(5 times,accounting for 55.56%).There was no significant difference in the cause distribution data of foodborne disease outbreaks caused by Vibrio parahemolyticus and other pathogens.Conclusions The proportion of foodborne disease outbreaks caused by Vibrio parahemolyticus is large in this area,and the patients were mainly middle-aged and elderly people,and the occurrence time of the incidents is concentrated in summer and autumn.Meat and aquatic products are the main suspect foods,and the patients have acute gastroenteritis as the main clinical manifestations,and the main cause of such incidents is cross infection.
