摘要: 目的 了解河北省2013-2015年引起急性上呼吸道感染(acute upper respiratory infection,AURI)的病原学构成和流行病学特征,为呼吸道感染的诊断和防治工作提供科学依据。方法 采集河北省4家医院门诊就诊的AURI患者的咽拭子标本1 551份,提取核酸后采用多重实时荧光定量聚合酶链式反应(polymerase chain reaction,PCR)方法检测15种呼吸道病毒。结果 采集1 551份临床咽拭子标本,检测出阳性标本714例,阳性率为46.03%,其中鼻病毒阳性率最高,为186(11.99%)例,其次为副流感病毒3型167(10.77%)例、呼吸道合胞病毒122(7.87%)例、腺病毒108(6.96%)例、乙型流感病毒56(3.61%)例、人偏肺病毒40(2.58%)例、甲型流感病毒39(2.51%)例、人博卡病毒38(2.45%)例、副流感病毒1型35(2.26%)例、冠状病毒229E/NL63型33(2.13%)例、肠道病毒32(2.06%)例、副流感病毒4型31(2.00%)例、冠状病毒OC43型30(1.93%)例、副流感病毒2型11(0.71%)例。病毒混合感染病例176例,检出率为11.35%。5岁以下年龄组病毒阳性率最高为56.07%(337/601)。结论 河北省AURI主要以鼻病毒、副流感病毒3型、呼吸道合胞病毒、腺病毒、流感病毒为主,各病毒有各自的流行特征。Abstract: Objective To investigate the viral etiology and the epidemilogy of acute upper respiratory tract infection in Hebei Province from 2013 to 2015, providing scientific basis for diagnosis, prevention and control of the respiratory tract infection. Methods 1 551 throat swab samples of the acute upper respiratory infection patients from four hospitals in Hebei Province were collected, Multiplex real-time PCR was used to detect 15 kinds of respiratory tract viruses for all specimens after nucleic acids extraction. Results Totally 714 positive samples were obtained from 1 551 samples, with a positive rate of 46.03%. Human rhinovirus(186, 11.99%)was detected as the most common viral species, followed by human parainfluenza 3(167,10.77%),respiratory syncytial virus (122,7.87%), adenovirus (108,6.96%),influenza B virus(56,3.61%), human metapneumovirus(40,2.58%), influenza A virus(39,2.51%), human boca virus (38,2.45%),human parainfluenza 1(35,2.26%),human coronavirus-229E/NL63(33,2.13%), human enterovirus (32, 2.06%), human parainfluenza 4(31,2.00%), human coronavirus-OC43(30,1.93%), and human parainfluenza 2(11,0.71%). 176 cases (11.35%) were detected as co-infection. The infection rate(56.07%) of under 5 years old group was higher than that of other groups. Conclusions The predominant respiratory viruses, who are responsible for acute upper respiratory tract infections in Hebei Province, are HRV, PIV3,RSV, ADV and IFV.Each virus possess the specific epidemiological feature.
