目的了解湖北省2011年手足口病(HFMD)流行特征,为制定防治措施提供依据。方法采用描述流行病学方法,对2011年湖北省各地上报HFMD病例以及重症、死亡病例数据进行分析。结果 2011年湖北省共报告HFMD病例63 767例,发病率为111.41/10万;其中重症病例159例,死亡24例。高发年龄为6月龄～3岁儿童,发病时间呈4～7月和10～12月双流行高峰,重症和死亡病例主要发生在4～7月流行高峰。病原学检测结果为肠道病毒71型(EV71)阳性1 439例(占53.02%),科萨奇病毒A16型(CoxA16)阳性776例(占28.59%),其他肠道病毒阳性499例(占18.39%),EV71为重症和死亡病例绝对优势病原。结论 2011年湖北省HFMD疫情处于较高流行水平,应重点加强第一个流行高峰和高发地区的HFMD预防控制工作。
Objective To understand the epidemiological characteristics of HFMD in Hubei Province in 2011 and provide the basis for the prevention and control measures. Methods Descriptive epidemiological methods were used to analyze the data of HFMD cases reported in 2011 and severe cases and deaths in Hubei Province. Results A total of 63 767 HFMD cases were reported in Hubei Province in 2011 with a prevalence of 111.41 / 100 000, of which 159 were severe cases and 24 died. High incidence of 6 months to 3 years old children, the onset time was 4-7 months and 10-12 months, the dual epidemic peak, severe and deaths occurred mainly in the 4 July peak. The etiological test results showed that 1 439 (53.02%) were positive for enterovirus 71 (EV71), 776 (28.59%) were positive for CoxA16, and 499 were positive for other enteroviruses 18.39%). EV71 is the predominant pathogen of severe and fatal cases. Conclusion The epidemic situation of HFMD in Hubei Province was at a relatively high prevalence in 2011, and the prevention and control of HFMD in the first endemic peak and high incidence areas should be emphasized.
