目的了解呼和浩特地区呼吸道腺病毒的感染情况。方法收集2009年-2012年呼和浩特地区呼吸道感染患者咽拭子样本,采用荧光PCR法进行扩增检测腺病毒部分核酸片段。结果 4年共检测1920份咽拭子,其中阳性样本为100份,阳性率为5.21%。腺病毒全年均可检出,检出高峰期主要集中在每年10月份到次年的3月份;不同年龄段人群对腺病毒的易感性不同,5岁以下儿童检出率高于5岁以上人群;男性检出率高于女性;不同职业人群中,托幼儿童的检出率最高。结论呼和浩特地区呼吸道腺病毒感染流行季节为冬春季节,5岁以下人群为高发人群。作为呼吸道感染重要病原体之一,应加强呼和浩特地区腺病毒流行情况的监测。
Objective To understand the infection of respiratory virus in Hohhot area. Methods Throat swab specimens from patients with respiratory tract infections in Hohhot from 2009 to 2012 were collected and amplified by fluorescent PCR to detect some of the adenovirus nucleic acid fragments. Results A total of 1920 pharyngeal swabs were detected in 4 years, of which 100 were positive and the positive rate was 5.21%. Adenovirus can be detected throughout the year, the peak was detected mainly in October each year to March of the following year; people of different ages susceptible to adenovirus, the detection rate of children under 5 years old is higher than 5 years old Population; male detection rate higher than women; different occupational groups, the highest detection rate of child care children. Conclusions The epidemic season of respiratory virus infection in Hohhot is winter and spring, while those under 5 years old are high incidence population. As one of the important pathogens of respiratory tract infection, the epidemic situation of adenovirus should be monitored in Hohhot area.
