2016年北京市门头沟区食源性疾病主动监测结果分析

Active surveillance results analysis of foodborne diseases in Mentougou District of Beijing in 2016

目的了解北京市门头沟区食源性疾病的流行病学特征。方法对2016年1月-12月两家哨点医院采集的粪便标本进行病原学检测。结果检测细菌标本389件,共分离出致病菌81株,检出率为20.82%,其中最主要的致病菌为致泻大肠埃希菌、副溶血性弧菌,检出率分别为9.51%、8.23%。检测病毒标本123件,检出病毒阳性34件,检出率为27.64%,其中轮状病毒检出率为14.63%,诺如病毒为13.01%。致病菌检出主要集中在5月-9月,病毒检出高峰在1月-4月、12月。食源性疾病高发的年龄组为0岁~10岁、21岁~30岁。结论基本掌握北京市门头沟区食源性疾病的流行病学特征。应重点关注0岁~10岁、21岁~30岁年龄组发病状况,食源性疾病主动监测需要发展和完善。

Objective To find out the epidemiological features of foodborne diseases in Mentougou District of Beijing.Methods To detect the stool specimens collected from two sentinel hospital for pathogen isolation and identification in 2016.Results 81 strains of pathogenic bacteria were isolated from 389 stool specimens,the total detection rate was 20. 82%,and the main pathogenic bacterium were diarrheogenic Escherichia coli（ 9. 51%） and Vibrio parahemolyticus（ 8. 23%）. 34 of 123 stool specimens were positive for virus detection（ 27. 64%）,and the detection rate of rotavirus was 14. 63%,the norovirus’ s was 13. 01%. Most of the pathogens were isolated from May to September. The detection peak of virus appeared from January to March and December. The age groups with high incidence of foodborne disease were concentrated in groups of 0-10 years old and 21-30 years old. Conclusion The study has basically revealed the epidemiological features of foodborne diseases in Mentougou District of Beijing. We need to pay close attention to the morbidity of the age groups of 0-10 years old and 21-30 years old. Active surveillance of foodborne diseases remains to be further improved.
