目的了解成都市食源性疾病发生情况及食源性疾病综合监测体系运行状况。方法采用社区居民食源性腹泻症状监测、疑似食源性腹泻哨点医院监测、食物中毒事件监测等方法开展综合监测。结果成都市社区居民食源性腹泻的4周发病率为1.0%,年发病率约为13.0%,就诊率为50%,住院率为6.3%。2012年医院门诊腹泻患者肛拭检测沙门菌阳性率4.1%、志贺菌阳性率0.3%,2013年沙门菌阳性率为0.8%。2012-2013年共监测到食物中毒事件20起,涉及中毒人数406人。结论综合监测结果显示成都市居民食源性疾病发病率较高,且存在明显的年份及季节差异。整个监测体系的运行也存在一定的问题,需在监测方法及质量控制上进一步探索和改善。
Objective To understand the occurrence of food-borne diseases and the status of comprehensive monitoring system of foodborne diseases in Chengdu. Methods The monitoring of foodborne diarrhea in community residents, the monitoring of suspected foodborne diarrhea sentinel hospitals and the monitoring of food poisoning incidents were carried out.
