2011年中国大陆手足口病流行特征分析

Epidemiology of hand, foot and mouth disease in mainland of China, 2011

  • 摘要: 目的 分析2011年中国大陆手足口病流行特征,探讨手足口病流行规律,为制定防控策略和措施提供依据。 方法 采用描述性流行病学方法对2011年国家《疾病监测信息报告管理系统》网络直报的手足口病监测资料进行分析。 结果 2011年全国共计报告手足口病1 619 706例,报告发病率为120.79/10万;死亡509例,死亡率为0.038/10万,病死率为0.031%。全年呈现夏季和秋冬季两个高峰,主高峰集中在夏季(5-7月),次高峰集中在秋冬季(10-12月)。重症病例和死亡病例也相应呈现两个高峰。在主高峰(5-7月)中,重症和死亡病例占总病例的比例为1.1%~1.2%,在次高峰(10-12月)中,重症和死亡病例占总病例的比例降到0.7%~0.8%。报告病例以5岁及以下儿童为主(占90%),其中重症病例和死亡病例集中在3岁及以下儿童(均占83%)。实验室病原监测显示肠道病毒71型(EV71)和柯萨奇病毒A组16型(Cox A16)仍为主要病原(合计占79%),各月份均以EV71为主,但10-12月Cox A16和其他肠道病毒所占比例较前期略有升高。 结论 2011年中国大陆手足口病发病流行强度与2010年相近,呈现夏季和秋冬季双峰模式;在秋冬季次高峰中重症及死亡病例比例低于在夏季高峰中的比例。

     

    Abstract: Objective understand the epidemiological characteristics of hand, foot and mouth disease (HFMD) in the mainland of China in 2011 and provide evidence for HFMD prevention and control. Methods Descriptive epidemiological analysis was conduct on the surveillance data of HFMD reported through national disease reporting information system in 2011. Results A total of 1 619 706 cases of HFMD, including 509 deaths, were reported in the mainland of China in 2011. The reported incidence was 120.79/lakh, the death rate was 0.038/lakh and the case fatality rate was 0.031%. The peak of the incidence, including severe cases and deaths, occurred in summer (May-July), and the sub peak occurred in autumn (October-December). The severe cases and deaths accounted for 1.1%-1.2% of the total cases during May-July, and the severe cases and deaths accounted for 0.7%-0.8% of the total cases during October-December. Most cases were children aged5 years (90%) and the severe cases and deaths mainly occurred in children aged3 years (83% for each). Etiological surveillance indicated that the major pathogens were EV71 and Cox A16 (totally 79%). EV71 was predominant all the year round, but the proportions of Cox A16 and other enteric virus increased slightly during October-December. Conclusion The incidence level of HFMD in 2011 was similar to that in previous years in the mainland of China, but two incidence peaks occurred, less severe cases or deaths occurred in autumn peak than in summer peak.
