儿童呼吸道合胞病毒肺炎流行特征分析

Analysis on the epidemic characteristics of children's respiratory syncytial virus pneumonia.

目的探讨小儿呼吸道合胞病毒肺炎流行特征,为有效防治提供依据。方法采用描述流行病学方法对2005年11月至2006年1月住院的肺炎患儿资料进行分析。结果386名住院患儿经直接免疫荧光法病原学确诊204名,其中3例腺病毒抗原阳性,占1.47%;3例流感A型病毒抗原阳性,占1.47%;198例呼吸道合胞病毒抗原阳性,占97.05%。<1岁组占64.14%;男女性别比为2∶1;无明显的聚集性。结论冬春季小儿肺炎以呼吸道合胞病毒肺炎多发,应加强监测和防治。

Objective This analysis was made to gain insight into the epidemic characteristics of children with respiratory syncytial virus pneumonia in order to provide the basis for effective prevention and treatment. Methods Descriptive epidemiology was adopted for analysis in hospitalized children patients with pneumonia from November 2005 to January 2006. Results 204 of all 386 hospitalized patients were diagnosed by direct immunofluorescence etiologic assay. 3 cases were adenovirus antigen-positive, accounting for 1.47%; 3 cases were influenza A virus antigen- positive, accounting for 1.47%; 198 cases were respiratory syncytial virus antigen-positive, accounting for 97.05%. Children younger than 1 accounted for 64.14%; the proportion of male to female was 2：1. There was no obvious aggregation. Conclusion Respiratory syncytial virus pneumonia was seen frequently among children in winter and spring. Hence, the monitoring and control should be strengthened.
