Syndromic surveillance in Guangzhou Asian Games,2010

目的介绍广州亚运会症状监测系统并分析其运行情况,探讨症状监测体系在大型运动会卫生保障中的应用。方法开发亚运会症状监测与涉亚人员健康监测信息系统,从2010年11月3日起通过亚运场馆医疗点、定点医院、接待酒店等途径收集所有涉亚人员发热、腹泻、皮疹、结膜红肿、黄疸等5类症状信息,对所有出现症状人员进行流行病学调查;同时收集同时期学生因病缺勤信息。采用敏感度、特异度等指标对监测体系进行评价。结果广州亚(残)运会期间,症状监测系统报告五大症状的患者476人次,其中发热症状163例,腹泻202例,皮疹61例,结膜红肿31例,黄疸0例,发热伴腹泻11例,发热伴皮疹4例,发热伴结膜红肿1例。学校学生症状监测各类症状7273人次,其中以咳嗽和发热为主;监测体系报告及时,病例症状发生到报告平均6.3h,聚集性症状报告平均2.5h,报告准确率99.78%,无传染病、食物中毒病例漏报。结论亚运会期间,基于驻馆医疗团队及公共卫生保障团队、定点医院主动监测为主要形式,发热、腹泻等五大类症状为监测内容的监测系统敏感性、特异性高,成本费用低,能及早地识别公共卫生事件的发生,可以广泛应用于大型活动的卫生保障实践。

Objective To analyze the syndromic surveillance system of Guangzhou Asian Games,and evaluate its application performance.Methods The syndromic surveillance system of Guangzhou Asian Games was developed to collect the syndromes of fever,diarrhea,rash,conjunctival redness and icterus from medical aid posts of Asian Games Venues,designated hospitals and hotels.The system also collected the data of absent students during the period of time in Guangzhou.The method of descriptive epidemiology was used for the study.The performance of the system was evaluated by the index of data sensitivity and specificity.Results There were 476 cases of reported syndromes in the syndromic surveillance system of Guangzhou Asian Games during the game period,including fever（163）,diarrhea（202）,rash（61）,conjunctival redness（31）,fever with diarrhea（11）,fever with rash（4） and fever with conjunctival redness（1）,respectively.There were 7 273 cases reported in school students,most of which were fever and cough.There were no unreported cases for infectious disease and food poisoning during the game period.The average time of gathering syndromes and reporting the symptoms from syndromes attacked were 2.5 and 6.3 hrs,respectively.The accuracy rate of reported syndromes was 99.78%.Conclusion The syndromic surveillance system of Guangzhou Asian Games provided concurrent data for disease symptoms with low cost and ensured quick response to the potential outbreak of infectious diseases and bioterrorist attack.
