摘　　要：目的探索2011-2013年黄浦区流感样病例(influenza like illness,ILI)流行特征、流感病毒亚型分布及不同监测数据的相关性。方法由监测点医院开展ILI监测,区CDC负责标本检测,通过幼托机构开展因病缺勤监测。结果 2011-2013年总ILI就诊百分比为0.33%,历年峰值依次出现在冬季、夏季和春季。2011-2013年流感病毒总阳性率为25.36%。2011年构成比最高的为B型流感病毒,2012-2013年均为A(H3)型。2011-2013年ILI就诊百分比、流感病毒阳性率和儿科急诊ILI就诊百分比均相关(均有P<0.05);2013年流感病毒阳性率和幼儿因上呼吸道症状缺勤百分比存在相关性(rs=0.36,P<0.05)。结论黄浦区ILI流行缺乏固定特征,幼儿因病缺勤监测结果可在一定程度上反映流感流行情况。Objective To explore the epidemiological and virological characteristics of influenza like illness （ILl） and correlation between different surveillance data in Huangpu district during 2011 -2013. Methods ILl surveillance was carried out in sentinel hospitals. Huangpu CDC was responsible for sample tests. Sickness absenteeism surveillance was conducted in pre-schools. Results During 2011 - 2013, the overall ILl consultation rate was 0. 33%, with the yearly peak falling in winter, summer and spring, chronologically. The total influenza virus positive rate was 25.36%. The most frequent subtype of influenza virus detected was B in 2011 and A（H3） in 2012 and 2013. During 2011-2013, ILI consultation rate correlated well with ILI consultation rate in pediatric emergency room and influenza virus positive rate （ all P 〈 0. 05）. In 2013, influenza virus positive rate correlated well with upper respiratory tract symptoms related absenteeism （ rs = 0. 36, P 〈 0. 05 ）. Conclusions There were no fixed features of ILl epidemics in Huangpu district. Absenteeism in preschools may partly tell influenza epidemics.
