目的评价全国传染病自动预警信息子系统疟疾预警系统的运行效果。方法收集中国疾病预防控制信息系统传染病自动预警信息子系统的疟疾预警信息,对江苏省疟疾预警信号进行统计,比较疟疾预警信息系统运行前后的3 d内完成个案流调率。结果 2012-09-01-2012-12-31,江苏省共接收到来自疟疾预警系统的手机短信消息85条,其中因重卡删除8条,县级疾控中心血片镜检复核和流行病学个案调查后排除15条,确认疟疾病例62例。2012年7-12月全省3 d内完成个案流调率分别为55.56%、78.57%、90.00%、100%、100%和100%,7、8、9月及10月间差异有统计学意义(χ2=10.66,P<0.05)。江苏省2012年7-12月的7 d内完成疫点调查与处置率均为100%。结论 3 d内完成个案流调率与预警手机短信有关联,传染病自动预警信息子系统的疟疾预警信息能有效提高基层疾控中心对疟疾病例的响应速度,对及时核实和判断疟疾病例具有重要作用。
Objective To evaluate the operational effectiveness of the early warning system for malaria in the National Automatic Warning Information System for Infectious Diseases. Methods The malaria warning information of China’s disease prevention and control information system was collected, and the malaria warning signal of Jiangsu Province was collected. The case flow rate was compared within 3 days before and after malaria warning information system was operated. Results 2012-09-01-2012-12-31, Jiangsu Province received a total of 85 mobile phone messages from the malaria warning system, of which 8 were deleted due to heavy truck, and the county-level CDC blood film microscopy review and epidemiology Fifteen cases were excluded after the case investigation, and 62 cases of malaria cases were confirmed. In July-December 2012, the number of case transfers completed within 3 days in the province were 55.56%, 78.57%, 90.00%, 100%, 100% and 100% respectively. There were statistically significant differences between July and December of 2012 and October Significance (χ2 = 10.66, P <0.05). Jiangsu Province completed the epidemic investigation and disposal rate within 7 days from July to December in 2012 both at 100%. Conclusions The rate of cases transferred within 3 days is related to early warning SMS. Early warning information of infectious disease automatic warning information subsystem can effectively improve the response speed of grass-roots CDC to malaria cases and is important for timely verification and judgment of malaria cases effect.
