福建省2005-2009年流行性乙型脑炎流行病学分析

目的了解福建省2005-2009年流行性乙型脑炎（乙脑）流行病学特征,为制定福建省乙脑监测及控制策略提供依据。方法对2005-2009年福建省乙脑疫情报告资料进行回顾性分析。结果福建省2005-2009年共报告174例乙脑病例,年均发病率0.0980/10万。历年发病率均低于全国同期水平。174例病例发生在除厦门市外的8个地市、57个县。7月份为发病高峰,占总病例的64.94%,其次为6月和8月。83.33%的病例集中在15岁以下儿童,在131例有调查资料的病例中,50.38%无免疫史。结论福建省自2004年将乙脑疫苗纳入儿童计划免疫后,乙脑发病率处于低发水平,控制效果较为显著。在乙脑高发地区必须进一步制定强有力的措施提高乙脑疫苗接种的及时率和全程接种率。
