【摘要】：目的分析海南省2011—2015年度流感暴发疫情的流行病学特征,为流感防控提供科学依据。方法收集2011—2015年度全省报告的流感暴发疫情资料,对暴发的时间、地区、场所、规模、病毒型别进行描述性流行病学分析。结果 2011—2015年度全省共报告流感暴发疫情21起,累计报告发病791例,平均罹患率3.17%,无死亡病例。暴发疫情主要发生在每年的3月和5月,占总起数的76.19%,疫情主要集中在中小学校,共20起(占总起数的95.24%)。农村地区报告疫情起数最多,占总起数的71.43%。暴发的优势循环株先后为B型流感,甲型H1N1流感,甲型H3N2亚型和B型流感。结论海南省流感暴发疫情具有明显的季节性,春季是高发季节,中小学校是流感暴发的高发场所,应加强农村学校流感样病例暴发疫情的监测,优势循环株变化频繁,应密切关注病原学变化。
