目的通过分析零陵区2008—2011年手足口病流行特点,掌握手足口病流行趋势,为制订手足口病防控策略提供科学依据。方法根据湖南省2008—2011年各年度手足口病监测实施方案,利用国家疾病监测信息报告管理系统的个案资料,对2008年1月至2011年12月零陵区内手足口病疫情资料进行流行病学分析。结果累计发病3 648例,年平均发病率为152.44/10万,重症174例,死亡7例。手足口病主要发病年龄段为0～5岁,占95.75%(3 493/3 648),散居儿童占95.20%(3 473/3 648);城、乡儿童手足口病发病率比较,差异有统计学意义(P<0.05)。结论 EV71感染是引起重症和死亡的主要原因;防控重点应放在0～5岁儿童,以降低重症病例和死亡病例的发生。
