目的了解哨点医院食源性疾病特定病原体分布情况及其流行病学特征,为食源性疾病防治提供依据。方法收集温州市食源性疾病监测哨点医院以腹泻症状为主诉且粪便或肛拭样本检测结果为病原体阳性的门诊和住院病例,进行临床症状、可疑食品暴露史调查,并对病原学检测结果进行分析。结果共收集317例病原体阳性食源性疾病病例,副溶血弧菌检出率最高,占67.91%(218/321)。检出7个血清群,O3:K6为优势血清型,呈现较明显的夏秋季高峰,成年人群中高发,尤其是26~35岁年龄段;其次为诺如病毒和沙门菌,分别有48株和44株,占14.95%(48/321)和13.71%(44/321)。0~5岁的儿童更易感染,全年均有检出,诺如病毒以GⅡ型为主,沙门菌以鼠伤寒沙门菌和肠炎沙门菌为主要血清型。所有患者均有不同程度的大便性状改变,水样便为主(96.85%)。可疑食品暴露史主要是水产及其制品、肉类、禽类及其制品以及蔬菜水果类。结论食源性疾病病例特定病原体分布情况、临床症状及可疑食品暴露史对食源性疾病的诊治、预防提供非常重要的意义,需完善食源性疾病监测网络,加快医疗机构信息化建设,提高临床实验室在监测过程中的支持作用,逐步完善食源性疾病监测、预警和控制体系。
Objective To understand the distribution and epidemiological characteristics of specific pathogens in foodborne diseases in sentinel hospitals, and provide the basis for the prevention and treatment of foodborne diseases. Methods To collect the outpatient and inpatient cases with diarrhea symptom as the main food source disease surveillance sentinel hospital in Wenzhou and the pathogen positive results from the fecal or anal swab samples and investigate the clinical symptoms and suspicious food exposure. Analyze. Results A total of 317 cases of pathogen-positive foodborne diseases were collected. The detection rate of Vibrio parahaemolyticus was the highest, accounting for 67.91% (218/321). Seven serogroups were detected. O3: K6 was the predominant serotype, showing the obvious peak in summer and autumn, especially in the age group of 26-35 years, followed by Norovirus and Salmonella, 48 And 44 strains, accounting for 14.95% (48/321) and 13.71% (44/321). 0 to 5-year-old children more susceptible, were detected throughout the year, norovirus as G Ⅱ-based, Salmonella typhimurium Salmonella typhimurium and enteritis as the main serotypes. All patients had different degrees of stool changes, water samples were the main (96.85%). Suspected food exposure is mainly the history of aquatic products and their products, meat, poultry and their products and vegetables and fruits. Conclusion The distribution of specific pathogens, clinical symptoms and suspicious food exposure history of food-borne diseases provide important significance for the diagnosis and prevention of food-borne diseases. The monitoring network of food-borne diseases should be improved and the information construction of medical institutions should be accelerated and improved Clinical laboratory support in the monitoring process, and gradually improve foodborne disease surveillance, early warning and control system.
