目的通过对2007-2008年度北京市流感监测数据分析,阐明北京市流感监测系统对流感高峰预警的有效性。方法2007-2008年度北京市共有153家医院开展了流感样病例监测;6家网络实验室开展了流感病原学监测。结果2007年9月至2008年4月,153家医院的平均流感样病例百分比为2.38%;共在14家医院采集流感样病例咽拭子2 057份,分离流感病毒611株,以乙型流感病毒Yamagata系为主。以流感病原学监测结果作为流感高峰来临的金标准,利用美国疾病预防控制中心开发的早期异常报告系统,对流感样病例监测数据进行分析,北京市流感样病例监测可以较好地对流感高峰的来临进行预警。结论北京市流感监测是北京市流感防控综合措施中不可或缺的组成部分,可以高效准确地对流感高峰进行预测和预警,同时也为未来流感大流行的预警做好了准备。
Objective To analyze the data of influenza surveillance in Beijing in 2007-2008 to illustrate the effectiveness of the influenza surveillance system in early warning of influenza in Beijing. Methods A total of 153 hospitals in Beijing were monitored for influenza-like illness in 2007-2008. Influenza etiology was monitored in 6 network laboratories. Results From September 2007 to April 2008, the average number of flu-like cases in 153 hospitals was 2.38%. A total of 2 057 throat swabs were collected from 14 hospitals and 611 influenza viruses were isolated. Influenza B Yamagata virus-based system. Influenza etiology monitoring results come as the gold standard for the advent of influenza, the use of the United States Centers for Disease Control and Prevention developed early abnormal reporting system, influenza-like case monitoring data analysis, flu-like cases in Beijing can better monitor the flu peak Arrival for early warning. Conclusion Influenza surveillance in Beijing is an indispensable component of comprehensive measures for influenza prevention and control in Beijing. It can predict and warn of influenza peak efficiently and accurately, and also prepare for the future alert of influenza pandemic.
