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,为制定流感预防控制策略提供参考。方法分析龙岗区2010—2011年流感样病例的流行病学、病原学检测、职业暴露人群人禽流感血清学监测等资料,探索流感流行规律。结果 2010—2011年龙岗区监测流感样病例55 429例,占监测就诊病例总数的7.24%(55 429/765 910);流感样病例主要集中在≤15岁年龄组,占80.55%;全年均有病例发生。两年间共分离出流感病毒毒株312株,阳性率38.61%(312/808);其中季节性流感A型96株,B型113株,甲型H1N1流感103株。两年共发生流感暴发疫情43起,累计发病例数458例;暴发时间多在3—5和12月,占总暴发疫情总数的83.72%,流感暴发疫情全部发生在学校和托幼机构;2010年暴发疫情主要为B型流感病毒(94.44%),2011年暴发疫情仍以B型流感病毒(76.00%)为主。结论龙岗区2010—2011年季节性流感发病相对平静,未发生较大规模的暴发流行,病毒毒株未发生明显变异。[ Objective ] To analyze the surveillance results of influenza in Longgang District of Shenzhen City in Guangdong, provide the reference for developing influenza prevention and control strategies. [ Methods] The epidemiological, etiological and serological surveillance data of influenza-like illness cases in Longgang District from 2010-2011 were analyzed to explore the epidemic pattern. [ Results] A total of 55 429 influenza-like illness cases were reported in Longgang District from 2010-2011, accounting for 7.24% （55 429/765 910） of the total outpatient cases. Most of cases were children under 15 years old, accounting for 80.55%. The in- fluenza-like illness cases occurred all the year round. During the two years, a total of 312 strains of influenza viruses were isolated with the positive rate of 38.61% （312/808）, including 96 strains of seasonal influenza A viruses and 113 strains of B viruses, 103 strains of influenza A H1N1. 43 influenza outbreaks occurred in two years, with 458 cases accumulatively. Most outbreaks occurred during March-May and December, which accounted for 83.72%, and all influenza outbreaks occurred in schools and nurseries. The influenza A viruses was predominant in outbreaks of both 2010（94.44% ） and 2011 （76.00% }. [ Conclusion] The epidemic situation of seasonal influenza in Longgang District from 2010-2011 is relatively stable without large-scale outbreaks, and no signifi- cant virus variation is observed.
