2013—2014年南京城北哨点医院食源性疾病监测情况分析

Analysis on monitoring results of foodborne diseases in sentinel hospital in northern Nanjing from 2013-2014

目的通过对南京城北哨点医院食源性疾病监测的结果进行分析,为食源性疾病的控制和早期治疗提供科学依据。方法收集2013—2014年南京城北1家哨点医院主动监测的病例信息和粪便标本,对标本中肠道病毒、非伤寒沙门菌、志贺菌、副溶血性弧菌、致泻性大肠埃希菌等病原体进行检验,对监测数据进行相关统计分析。结果 583份标本中,病毒检出率为31.73%(185/583),其中诺如病毒110份;病原菌检出率为2.57%(15/583),其中副溶血性弧菌8份;不同季度之间的病毒阳性检出率差异有统计学意义(P<0.05),病原菌阳性检出率差异无统计学意义(P>0.05)。25~44岁年龄组为高发人群,第二季度、第三季度为发病高峰期;可疑食物中肉与肉制品所占比例最大。结论南京城北地区食源性疾病感染的主要病毒为诺如病毒,其次为轮状病毒;病原菌感染主要以副溶血性弧菌为主。应加强健康宣教和卫生管理,完善食源性疾病哨点医院监测制度,提高监测水平,增强食源性疾病防控能力。

Objective To analyze the monitoring results of foodborne diseases in sentinel hospital in northern Nanjing,so as to provide scientific basis for the clinical prevention and treatment. Methods The cases of foodborne diseases from the sentinel hospital were statistically analyzed. The samples collected from patients with foodborne diseases were detected for Norovirus,non-typhoid Salmonella,Shigella,Vibrio parahaemolyticus,Escherichia coli according to national standards.Results Among 583 stool samples,virus counted for 31. 75%（ 110 /583）,in which 110 strains were Norovirus,and pathogenic bacteria counted for 2. 57%（ 15 /583）,in which 8 strains were Vibrio parahaemolyticus. There was significant difference in virus detection rate between different quarter（ P 0. 05）,but there was no significant difference in pathogenic bacteria detection rate between different quarter（ P 0. 05）. The high risk populations were people in 25-44 age groups. The second and the third quarter of the year were the peak period. Meat and meat products accounted for the greatest proportion of suspected food. Conclusion Norovirus was the predominant pathogen causing foodborne disease followed by Rotavirus.Pathogenic bacteria infection was mainly caused by Vibrio parahaemolyticus. It was necessary to strengthen the health education and management,improve the monitoring system of the sentinel hospital,strengthen the active monitoring,and prevent the spread of the disease.
