请引用本文如下：Chittaganpitch et al.（2012）泰国流感病毒：2004-2010年7年哨点监测数据。流感和其他呼吸道病毒6(4),276-283。2004年甲型H5N1禽流感的再次出现和2009年甲型H1N1流感的大流行突出表明，需要建立常规监测系统来监测流感病毒，特别是在禽类中流行H5N1的东南亚。2004年，泰国国家卫生研究所与美国疾病控制和预防中心合作，在泰国各地建立了流感哨点监测。目的回顾流感病毒的常规流行病学和病毒学监测情况，为公共卫生行动提供依据。方法收集2004-2010年11个哨点流感样疾病和严重急性呼吸道疾病患者的咽拭子。使用聚合酶链反应的标准方案鉴定流感病毒。采用免疫荧光法对病毒进行培养鉴定；用血凝抑制试验鉴定菌株。对数据进行分析，以描述流行菌株的频率、季节性和分布。结果19 457份咽拭子中，流感病毒阳性3967份（20%），甲型流感阳性2663份（67%），可分亚型[H1N1占21%，H3N2占25%，大流行（pdm） H1N1占21%]，乙型流感阳性1304份（33%）。2009-2010年监测系统共检出3波pdm H1N1。流感每年有两个高峰，一个主要高峰在雨季（6 - 8月），一个次要高峰在冬季（10 - 2月）。结论3 - 4月可能是泰国季节性流感疫苗接种最适宜的月份。该系统提供了泰国流感病毒流行病学的可靠概况，并已证明对公共卫生规划有用。

Background The re‐emergence of avian influenza A (H5N1) in 2004 and the pandemic of influenza A (H1N1) in 2009 highlight the need for routine surveillance systems to monitor influenza viruses, particularly in Southeast Asia where H5N1 is endemic in poultry. In 2004, the Thai National Institute of Health, in collaboration with the US Centers for Disease Control and Prevention, established influenza sentinel surveillance throughout Thailand. Objectives To review routine epidemiologic and virologic surveillance for influenza viruses for public health action. Methods Throat swabs from persons with influenza‐like illness and severe acute respiratory illness were collected at 11 sentinel sites during 2004–2010. Influenza viruses were identified using the standard protocol for polymerase chain reaction. Viruses were cultured and identified by immunofluorescence assay; strains were identified by hemagglutination inhibition assay. Data were analyzed to describe frequency, seasonality, and distribution of circulating strains. Results Of the 19 457 throat swabs, 3967 (20%) were positive for influenza viruses: 2663 (67%) were influenza A and able to be subtyped [21% H1N1, 25% H3N2, 21% pandemic (pdm) H1N1] and 1304 (33%) were influenza B. During 2009–2010, the surveillance system detected three waves of pdm H1N1. Influenza annually presents two peaks, a major peak during the rainy season (June–August) and a minor peak in winter (October–February). Conclusions These data suggest that March–April may be the most appropriate months for seasonal influenza vaccination in Thailand. This system provides a robust profile of the epidemiology of influenza viruses in Thailand and has proven useful for public health planning.
