摘要
目的:描述江苏省甲型H1N1流感暴发疫情的流行特征,分析影响学校甲型H1N1流感疫情流行强度的因素。方法:调查和收集江苏省2009年夏秋季报告的全部甲型H1N1流感暴发疫情数据,包括暴发疫情的强度、暴发单位的一般情况、控制疫情的措施等,对疫情的流行特征进行描述性研究,对影响学校疫情强度的因素进行单因素和多因素Logistic回归分析。结果:截止11月上旬共报告79起甲型H1N1流感暴发疫情,其时间主要集中在8月中旬至9月中旬,累计发病1735人,以学校为主要暴发单位;疫情的流行时间与疫情报告的及时性有关(P<0.01),报告越及时流行时间越短,疫情的罹患率与疫情报告时已有病例数有关(P=0.006);疫情报告时已有病例越多罹患率越高。结论:江苏省第一次甲型H1N1流感暴发疫情高峰出现在8、9月份,疫情报告的及时性对控制疫情的强度起关键作用。
