    摘要:

    目的:探讨苏州地区儿童急性下呼吸道鼻病毒感染的流行特点及与气候因素的相关性。方法:2013年1—12月对因急性下呼吸道感染住院的1 926例儿童,运用实时定量PCR法检测鼻咽抽吸物(NPA)人鼻病毒(HRV),收集同期苏州地区月平均气温-平均湿度-总降水量-总日照时间-平均风速等气象资料。采用Spearman秩相关法分析鼻病毒活性与气候因素的相关性。结果:2013年1—12月间苏州地区下呼吸道感染儿童HRV的检出率为11.1%,且多见于3岁以下患儿(81.3%);HRV感染好发于夏-秋季;HRV检出率与月平均气温呈正相关。结论:HRV是苏州地区儿童急性下呼吸道感染的重要病原之一,气候因素尤其是气温对HRV的流行可能有影响。

    Abstract:

    Objective:To explore the epidemiology of human rhinovirus (HRV) infection in children with acute low respiratory tract infection and its relationship with meteorological conditions in Suzhou. Methods: A total of 1 926 children with acute low respiratory tract infection were participated in the trial during January to December 2013,and the nasopharyngeal aspirates were collected for HRV detection with real time PCR. Meanwhile meteorological conditions including mean temperature, relative humidity, total month rainfall, sum of sunshine, and mean wind velocity were collected monthly during the same period. The relationship between the epidemic of HRV and meteorological conditions were analyzed by Spearman rank correlation analysis. Results: HRV was identified in 11.1% of 1 926 specimens,81.3% patients with HRV infection were younger than 3 years old;The prevalence of acute HRV infection was higher during summer and spring. HRV detection rate was positively correlated with the monthly mean temperature. Conclusion: HRV is a common pathogen in hospitalized children with lower respiratory tract infection in Suzhou. Meteorological factor,especially temperature may affect the prevalence of HRV.
