目的了解舟山市手足口病疫情流行特征，为制定防控措施提供参考依据。方法采用描述流行病学方法对2008—2011年报告的手足口病病例进行分析。结果2008--2011年舟山市共报告手足口病1831例，重症病例7例，无死亡病例，呈散发状态，未发生暴发疫情，年均发病率为41．10／10万。定海区年均发病率最高（52．11／10万），岱山县最低（26．26／10万）。男性发病高于女性，以散居儿童和幼托儿童为主，集中于0～5岁儿童，占96．18％。发病高峰一般在4—8月，2008年和2009年有2个发病高峰，2010年和2011仅有一个发病高峰。病原学监测结果显示以EV71和其他肠道病毒为主，7例重症病例中，均检测EV71型阳性。结论舟山海岛地区手足口病发生有明显的年龄、性别、职业和季节差异，流行毒株以EV71和其他肠道病毒为主，重症病例流行毒株以EV71为主。
