浙江省衢州市传染病自动预警系统运行状况分析

Preliminary application of China infectious diseases automated-alert and response system in Quzhou city

目的:了解传染病预警系统在衢州市的运行情况。方法:对2008年4月21日-2011年6月30日预警系统产生的预警信号、信号响应率、响应时间、初步判断核实和暴发数据进行描述性分析。结果:2008年4月21日-2011年6月30日,衢州市共接到传染病预警系统发出的预警信号2724条,预警信号响应率99.96%,24 h信号核实率为95.04%,移动百分位法报告病例数与预警信号数的比值为7.12∶1。疑似事件占全部预警信号的3.05%,疑似事件阳性率为19.28%。结论:预警系统已初步实现传染病暴发的早期探测预警,但仍需进一步改进和完善。

Objective：To analyze the application of China Infectious Diseases Automated-alert and Response System（CIDARS）.Methods： Amount of signal,proportion of signal response,time to signal response,manner of signal verification and outbreak data were descriptively analyzed from April 21,2008 to June 30,2011.Results： A total of 2724 signals,relating to 18 kinds of infectious diseases,were generated in Quzhou in CIDARS.99.96% of the signals han been responsed and median time to response was 1.23 h.The ratio of number of reported cases and warning signals was 7.12∶ 1 by using moving percentile method.3.05% of all warning signals were considered to be related to suspected events via the preliminary verification and 19.28% of the suspected events were confirmed as outbreak by further field investigation.Conclusion： The system seemed to have worked on the outbreak early warning of infectious diseases,but still need to further improve and perfect.
