流感样病例和核酸检测阳性率相关性分析

目的:通过江苏省流感监测数据,分析流感样病例(influenza-like illness,ILI)和流感病毒核酸检测阳性率的相关关系?方法:比较江苏省2011~2013年30周不同年龄组间ILI报告数?核酸检测阳性率有无差异,并分析ILI和核酸检测阳性率的相关性?结果:2011~2013年30周我省3个年龄组ILI数差异均有统计学意义,核酸检测阳性率差异也均有统计学意义,0~4岁和5~14岁年龄组ILI与核酸阳性率相关系数无统计学意义,但是15岁及以上年龄组两者相关系数有统计学意义?结论:通过提高ILI报告质量?标本采集质量及监测方案的适时调整,可以获得更加科学有效的流感监测工作效果?

Correlation of influenza-like illness and positive rate of nucleic acid

Objective:To analyze the correlation of ILI and positive rate of nucleic acid based on data of influenza surveillance in Jiangsu Province. Methods:The ILI number and positive rate of nucleic acid detection among age groups of three years in Jiangsu Province were caculated and the correlation of ILI and the positive rate was analyzed. Results:From 2011 to the 30th week of 2013,there were differences between ILI and positive rate of nucleic acid detection among age groups.The correlation of ILI and the positive rate of nucleic acid detection was not statistically significant between age of 0~4 years and 5~14 years,although it was significantly different among age groups >14 years. Conclusion:We can achieve more scientific and effective influenza surveillance by improving the quality of ILI reporting and specimen collection and adjustment the monitoring program.
