云浮地区4475例呼吸道合胞病毒检测结果分析

Analysis of respiratory syncytial virus detection outcomes of 4475 cases in Yunfu

目的了解云浮地区儿童呼吸道合胞病毒(RSV)感染规律。方法通过直接免疫荧光法检测4475例患儿鼻咽拭子,筛查出阳性标本后再通过同样的方法学鉴定出RSV,收集整理云浮地区2014年1~12月所有RSV检测结果并进行分析。结果 RSV阳性611例(13.65%),男性患儿占69.23%,患儿感染RSV年龄高峰在1月龄和12月龄,1~5月份RSV检出阳性率较其他月份高。结论 RSV有相对固定的地区性流行规律,容易引起婴幼儿呼吸道疾病,男性比女性患病率高,值得地区卫生部门重视。

ObjectiveTo understand infection regularity of children respiratory syncytial virus （RSV） in Yunfu.Methods Direct immunofluorescent method was applied to detect nasopharyngeal swab in 4475 children, followed by RSV detection in positive samples. RSV detection outcomes during January^December 2014 in Yunfu were summarized for analysis.Results There were 611 positive RSV cases （13.65%）, and male children were accounted for 69.23%. RSV infection peak ages included 1-month old and 12-month old. Positive detection rates of RSV during January^May were higher than rate of the other months.Conclusion Relatively fixed regional epidemic regularity of RSV leads to infantile respiratory disease, which shows higher morbidity in male than female. It is worth attention from regional health department.
