摘要
目的了解上海市非伤寒沙门菌(以下简称"沙门菌")感染的流行病学特征,为沙门菌感染的预防和控制提供科学依据。方法应用描述流行病学的方法,对上海市26家食源性疾病监测哨点医院感染性腹泻病例的流行病学信息和沙门菌检测结果进行统计分析。结果收集到5580例感染性腹泻病例和其标本,沙门菌检出率为4.19%(234/5580),其血清型以肠炎沙门菌和鼠伤寒沙门菌为主。不同性别、年龄和职业人群的沙门菌检出率差异无统计学意义(P>0.05),春夏季节是沙门菌检出的高发季节。有发热症状或者发生水样便的病例,其沙门菌检出率高于无发热症状和无水样便的病例。餐饮服务业和单位食堂的病例中沙门菌检出率相对较高。结论上海市沙门菌感染的血清型以肠炎沙门菌和鼠伤寒沙门菌为主,感染高峰出现在春夏季节。考虑到餐饮服务业和单位食堂的风险相对较高,食品安全监督管理部门应加强对其卫生监管。
Objective To identify the epidemiological characteristics of nontyphoid Salmonella infection in Shanghai,and provide scientific basis for the prevention and control.Methods The descriptive epidemiological method was used to analyze the epidemiological information of the collected diarrhea cases and the nontyphoid Salmonella test result from 26 foodborne disease surveillance sentinel hospitals in Shanghai.Results A total of 5580 infectious diarrhea cases and specimens were enrolled.The positive detection rate of nontyphoid Salmonella was 4.19%(234/5580).The serotypes were mainly Salmonella Enteritidis and Salmonella Typhimurium.There was no difference in the positive detection rate of nontyphoid Salmonella among different genders,ages and occupations.Spring and summer were the seasons when nontyphoid Salmonella positive detection rate was high.The positive rate of nontyphoid Salmonella in patients with fever or watery stool was significantly higher than in patients without fever or waterless stool.The positive rate of nontyphoid Salmonella was relatively high among the patients from small and medium-sized catering service and canteen.Conclusion Salmonella Enteritidis and Salmonella Typhimurium were the main serotypes of nontyphoid Salmonella in Shanghai,and the peak of nontyphoid Salmonella infection occured in spring and summer.The authorities should strengthen the supervision and management of catering service and canteen.
