2019—2021年上海市宝山区食源性疾病病原体监测结果分析

Analysis of monitoring results of foodborne pathogens in Baoshan District， Shanghai， 2019‒2021

    摘要
  • 摘要:
    目的 了解上海市宝山区食源性疾病致病菌监测情况及流行特点，提高食源性疾病暴发的早期识别与预警能力，为食源性疾病的防控提供科学依据。
    方法 对上海市宝山区2家哨点监测医疗机构在2019—2021年采集的食源性腹泻病例肛拭或粪便样本开展沙门菌、致泻性大肠埃希菌、志贺菌、副溶血性弧菌、弯曲菌和诺如病毒检测，并对检测的结果进行统计学分析。
    结果 2019—2021年上海市宝山区共报告食源性疾病病例1 693例，采集样本1 693份，男女性别比为1.04∶1，年龄以45~64岁组最多（504例），生活状态以离退休人员报告病例最多（762例），夏秋季为食源性疾病高发期，暴露食品中肉与肉制品导致的食源性疾病最多（566例），家庭是暴露的主要场所（1 260例）。致病菌检出率为21.32%，主要为弯曲菌（10.28%），发病期主要集中在每年的5—9月。诺如病毒检出率为13.29%，冬春季为疾病高发期。沙门菌优势血清为肠炎沙门菌（41.82%），致泻性大肠埃希菌本地优势血清型为EAEC （50.52%），弯曲菌以空肠弯曲菌为主（81.61%），诺如病毒以诺如病毒GⅡ型为主（60.87%）。
    结论 引起上海市宝山区食源性疾病的病原体中弯曲菌所占比例最高，致泻大肠埃希菌次之，病毒以诺如病毒GⅡ型为主，应结合各病原体流行特征采取相应的防控措施。

     

    Abstract:
    Objective To investigate the monitoring status and epidemiological characteristics of foodborne disease pathogens in Baoshan District， Shanghai so as to improve early detection and warning capabilities of foodborne diseases outbreaks， and to provide a scientific basis for the prevention and control of foodborne diseases.
    Methods Anal swabs or fecal samples from food-borne diarrhea cases were collected from two sentinel surveillance medical institutions in Baoshan District of Shanghai during 2019 and 2021.Salmonella， diarrheagenicEscherichiacoli，Shigella，Vibrio parahaemolyticus，campylobacterandnorovirus were tested in anal swabs and fecal samples， and all the testing results were statistically analyzed.
    Results A total of 1 693 cases were reported， among which 1 693 anal swabs and fecal samples were collected， with a male-to-female ratio of 1.04∶1. The largest number of cases was from the age group of 45-64 years （504 cases）. The highest number of reported cases was among retirees （762 cases）. The high-incidence period of the diseases was in summer and autumn， with the highest number of cases associated with meat and meat products （566 cases）. The primary location of exposure was at home （1 260 cases）. The detection rate of pathogenic bacteria and virus was 21.32%， among whichcampylobacteraccounted for the largest proportion （10.28%）. The peak incidence rate was from May to September. The detection rate of norovirus was 13.29%， with a higher incidence in winter and spring. The predominant serotype ofSalmonellawasSalmonellaenteritidis （41.82%）， and the predominant local serotype of diarrheagenicEscherichia coliwas EAEC （50.52%）.Campylobacterwas mainly represented by jejuni （81.61%）， and the predominant type of norovirus was GⅡ （60.87%）.
    Conclusion Campylobacterhas the highest proportion among foodborne pathogens causing foodborne diseases in Baoshan District， followed by diarrheogenicEscherichia coli. And norovirus GⅡ type is the predominant virus. Appropriate prevention and control measures should be taken based on the characteristics of each pathogen's epidemiology.
