摘　　要：目的了解甘肃省张掖市2009—2010年国家哨点医院流感样病例(ILI)监测结果,掌握流行性感冒(流感)流行趋势及病毒株变化特点,为制定预防和控制策略提供依据。方法对2009—2010年哨点医院门急诊ILI三间分布及网络实验室结果进行统计分析。结果 2009—2010年张掖市报告ILI1176例,流感样病例就诊比例(ILI%)为0.94%;ILI主要集中在15岁以下儿童,887例,占72.11%,尤其是5岁以下儿童490例,占41.67%,呈现出年龄越小ILI越多的趋势;1～5月份ILI%处于较低水平,6～10月份呈递增趋势,11月份达最高点。共检测咽拭子标本632份,流感病毒核酸阳性161份,检出率为25.47%,其中甲型H1N1流感74例,阳性构成比为45.96%,季节性流感87例,阳性构成比为54.04%,2009年甲型H1N1为优势毒株。报告流感暴发4起,B型、甲型H1N1流感各2起,B型流感发生在农村小学,甲型H1N1流感发生在城区中学。结论 2009年流感活动十分活跃,以甲型H1N1流感为主。学校是流感暴发的高发场所,要做好与教育部门的协调沟通,指导学校在秋冬季及早做好宣传、晨检、通风、保暖、卫生和接种等防控措施。加强哨点医院管理,强化院内培训,消除零周报,提高采样数量、质量,合理保存样品,提高核酸阳性率和病毒分离率。OBJECTIVE Understanding of Zhangye City in Gansu Province,the national sentinel hospitals in the 2009-2010 influenza-like illness（ILI）surveillance,control of influenza（flu）virus strains change trends and characteristics of strategies for prevention and control provide the basis.METHODS On the 2009-2010 Hospital of sentinel ILI three distribution and statistical analysis of network laboratory results.RESULTS Zhangye City in the 2009-2010 report ILI1176 cases,the proportion of influenza-like illness visits （ILI%）0.94%;ILI mainly in children under the age of 15,887 cases,accounting for 72.11%,in particular the 490 cases of children under 5 years old,accounting for 41.67%,showing a younger more ILI trends;ILI% from January to May at a low level of 6-October showed an increasing trend,in November reached the highest point.632 copies were detected in throat swab specimens,161 were positive for influenza virus nucleic acid,the detection rate of 25.47%,of which 74 cases of influenza A H1N1 influenza,constitute more than 45.96% positive,87 cases of seasonal influenza,the positive ratio of 54.04% constitute,2009 Influenza A H1N1 was the dominant strain.Report from the outbreak 4,B-type,H1N1 from the 2,B-type influenza have occurred in rural primary schools,H1N1 occurred in urban secondary schools.CONCLUSION Influenza activity is very active in 2009,mainly to influenza H1N1 influenza.Schools are places of high incidence of epidemic outbreaks,the education sector to promote good early in the autumn and winter,morning check,ventilation,warmth,sanitation,vaccination and other control measures.Strengthen the management of sentinel hospitals,streng thening hospital training,elimination of zero-weekly,increase the sampling quantity,quality,reasonable sample preservation and improve the positive rate of nucleic acids and virus isolation rate.
