摘  要:调查2009-2010年上海地区人群急性呼吸道感染(ARTI)的病毒性病原,探讨2009甲型H1N1流感暴发背景下呼吸道感染病毒病原谱的构成。采用套式多重反转录-聚合酶链反应(RT-PCR)和实时荧光定量RT-PCR方法,对来自2 044例患者的2 044份标本(包括2 005份鼻咽拭子和39份肺泡灌洗液),同时检测腺病毒(ADV)、副流感病毒(PIV)、甲型流感病毒(FluA)、乙型流感病毒(FluB)、微小核糖核酸病毒、呼吸道合胞病毒(RSV)、人偏肺病毒(hMPV)、冠状病毒(CoV)和人博卡病毒(HBoV)。其中,656(32.09%)份标本经呼吸道病毒检测为阳性,52份标本为双重感染。FluA检出率最高(13.36%),其后依次为微小核糖核酸病毒(10.23%)、FluB(4.84%)、ADV(1.96%)、PIV(1.76%)、RSV(1.32%)、CoV(0.59%)、hMPV(0.39%)和HBoV(0.20%)。但各月病毒检出率分布不均,2009和2010年呼吸道病毒检出率高峰出现在当年11月(53.07%和65.59%),低谷都出现在当年5月,且2009年5-9月的病毒检出率高于2010年同期(32.02%vs15.38%,P〈0.05)。其中,2009甲型H1N1流感暴发导致2009年10月-2010年1月2009甲型H1N1流感病毒占当月检出FluA的100%,2009年6-9月也占当月检出FluA的较高比率,依次为90.91%(20/22)、75.00%(15/20)、48.00%(12/25)和56.25%(18/32)。比较甲型H3N2流感病毒和2009甲型H1N1流感病毒分别在上呼吸道感染(URTI)和下呼吸道感染(LRTI)中的检出率,无统计学差异(URTI,85.29%vs76.61%;LRTI,14.71%vs23.39%;P〉0.05)。呼吸道病毒检出率还与年龄相关,0-4岁组和5-14岁组病毒检出率高于其他年龄组。在0-4岁及≥65岁组中,微小核糖核酸病毒检出率最高,FluA次之;其余年龄组中FluA检出率最高。混合感染中15岁以下儿童占50%(26/52),微小核糖核酸病毒与其他病毒混合感染占84.62%(44/52)。本研究表明,上海地区2009-2010年FluA是最常见的急性呼吸�The present paper aims to understand the viral etiology in patients with acute respiratory tract infections(ARTIs) in Shanghai area during 2009-2010 and to explore the respiratory viral spectrum under the background of 2009 A(H1N1) influenza outbreak worldwide.A total of 2 005 nasopharyngeal swab and 39 lavage fluid specimens from 2 044 patients were analyzed by nested multiplex reverse transcriptase-polymerase chain reaction(RT-PCR) and real-time quantitative RT-PCR for detection of common respiratory viruses,including adenovirus(ADV),parainfluenza virus(PIV),influenza virus A(FluA),influenza virus B(FluB),picornavirus,respiratory syncytial virus(RSV),human metapneumovirus(hMPV),coronavirus(CoV),and human Boca virus(HBoV).The results showed that 656 out of 2 044 specimens(32.09%) were positive for one or more viruses,52 specimens were positive for two viruses.FluA(13.36%) was the dominant agent detected,followed by picornavirus(10.23%),FluB(4.84%),ADV(1.96%),PIV(1.76%),RSV(1.32%),CoV(0.59%),hMPV(0.39%),and HBoV(0.20%).The viral detection rates changed regularly within the two-year study period.The peak detection rate occurred in November and the lowest rate occurred in May within the two-year study period.The viral detection rate during May to September in 2009 was significantly higher than the rate during the same period in 2010(32.02% vs 15.38%,P0.05).Additionally,during October 2009 to January 2010,all FluA-positive specimens were 2009 A(H1N1) influenza virus and the frequencies(ratios) of 2009 A(H1N1) influenza virus in FluA positive-specimens were 90.91%(20/22),75.00%(15/20),48.00%(12/25) and 56.25%(18/32) in June,July,August,and September in 2009,respectively.The frequency of upper respiratory tract infections(URTIs) or lower respiratory tract infections(LRTIs) caused by H3N2 or 2009 A(H1N1) influenza virus was similar(URTI,85.29% vs 76.61%;LRTI,14.71% vs 23.39%;P0.05).Viral d
