摘要
目的了解2013年-2014年淮安市流感的流行趋势,为本地区流感的防控提供病原学依据。方法通过中国流感监测信息系统,统计分析淮安市2家哨点医院采集的流感样病例数据及网络实验室对哨点医院采集标本的核酸检测结果,分别从ILI年龄构成、ILI性别构成、流感季节分布等指标来进行比较分析。结果淮安市国家级流感监测网络实验室共收集并检测1 349份标本,阳性率为15.49%。0岁~4岁年龄组和5岁~14岁年龄组流感病毒检测阳性率较高,分别为31.55%和21.52%。春季、秋季、冬季的流感病毒检出率较高,阳性率分别为16.87%、15.92%、21.66%。结论流感流行高峰多见于春季、秋季和冬季,0岁~4岁年龄组和5岁~14岁年龄组发病率较高,提示流感的重点防护人群为儿童。
Objective To investigate the epidemic characteristics of influenza in Huai＇an from 2013 to 2014,so as to provide basis for the prevention and control of influenza. Methods Through the Chinese influenza monitoring information system,the data of influenza- like cases collected from 2 sentinel hospitals in Huai＇an and the nucleic acid detection results of the network laboratory were analyzed. Comparison was conducted on the ILI age constitution,ILI sex constitution,and influenza seasonal distribution. Results A total of 1 349 ILI cases were collected from the national influenza surveillance network laboratories in Huai＇an and tested,with the positive rate of 15. 49%. The positive rate of children aged 0- 4 years old and children aged 5-14 years old were higher,respectively 31. 55% and 21. 52%. During spring,autumn and winter,the positive rates were higher,respectively 16. 87%,15. 92% and 21. 66%. Conclusion The influenza peaks are epidemic in spring,winter and summer. Children aged 0- 4 years old and children aged 5- 14 years old are with the higher occurrence,which suggests that children are the focus of the flu protection groups.
