2005-2007年深圳市龙岗区流感样病例监测分析

Surveillance of influenza-like illness in Longgang district of Shenzhen city, Guangdong province, 2005-2007

  • 摘要: 目的 分析广东省深圳市龙岗区流行性感冒(流感)监测的结果,掌握并初步预测流感流行趋势和病毒毒株变异情况。方法 分析龙岗区2005-2007年流感流行病学、病原学、血清学监测资料,探索流感流行规律。 结果 2005年2月至2007年12月龙岗区上报流感样病例26 644例,占监测就诊病例总数的5.30%(26 644/503 182);疾病主要集中在15岁年龄组(占83.17%);全年均有病例发生,5-9月发病数占62.70%(16 707/26 644);分离出流感病毒毒株20株,阳性率1.96%;其中A型16株和B型4株。3年共发生暴发疫情37起,累计发病例数605例;暴发时间多在3-6月,主要发生在中、小学校;病原学检测2005年、2007年以甲型流感病毒(73.33%)为主,2006年以乙型流感病毒(68.18%)为主。结论 龙岗区2005-2007年流感发病相对平静,未发生较大规模的暴发流行,病毒毒株未发现明显变异。

     

    Abstract: Objective To analyze the surveillance results of influenza in Longgang district of Shenzhen city, Guangdong province and predict the epidemic trend of influenza and the virus variation. Methods The epidemiological, etiological and serological surveillance data of influenza in Longgang district from 2005 to 2007 were analyzed to explore the epidemic pattern. Results A total of 26 644 influenza-like illness cases were reported from February, 2005 to December, 2007, accounting for 5.30% (26 644/503 182) of the total outpatient cases, and most cases occurred among children aged 15 years (83.17%). Influenza occurred all the year round, and the cases during May-September accounted for 62.70% (16 707/26 644). A total of 20 strains of influenza virus were isolated with the positive rate of 1.96%, including 16 strains of A virus and 4 strains of B virus. During this 3-year period, 37 outbreaks occurred with 605 cases accumulatively. Most outbreaks occurred during March-June and in primary and middle schools. Etiological test indicated that A virus was predominant in 2005 and 2007 (73.33%) and B virus was predominant in 2006 (68.18%). Conclusion The influenza activity in Longgang district from 2005 to 2007 was relatively stable without large-scale outbreaks and no significant virus variation was observed.
