【摘要】：目的分析2009-2016年内蒙古地区重症手足口病的流行特征以及时空分布特征,明确防控工作的重点地区、时间、人群,进而降低重症病例的发生。方法对收集到的2009-2016年内蒙古手足口病监测数据中的重症病例进行流行病学和时空聚集性分析。结果 2009-2016年重症病例发生率呈先升后降趋势,2011年是8年间重症发生率的峰值。重症手足口病的发病年龄主要集中在0~3岁年龄组,其中散居儿童最多,男性儿童的发病率高于女性儿童。重症手足口病每年的高发时间为6~7月。2009-2016年,累计报告重症手足口病病例1 278例,占总病例的0.78%,8年年均重症发病率50.70/100万。肠道病毒71型(EV71)是引起手足口病重症病例的主要病原体。重症手足口病发病存在明显的时空聚集性,时间维度为5~7月,空间维度上主要分布在内蒙古的中部和西南地区。结论内蒙古地区重症手足口病的发病具有时空聚集性,发病强度具有地区差异性,气候可能为疫情高发的相关因素。3岁以下儿童是主要发病人群,需加强对年龄较小患者的重症预防,以减少重症病例的发生。
[Abstract]:Objective to analyze the epidemic characteristics and temporal and spatial distribution of severe hand, foot and mouth disease (HFMD) in Inner Mongolia from 2009 to 2016, to determine the key areas, time and population of prevention and control, and then to reduce the incidence of severe cases. Methods Epidemiology and temporal and spatial aggregation of severe cases collected from the surveillance data of hand, foot and mouth disease from 2009 to 2016 in Inner Mongolia were analyzed. Results the incidence of severe cases increased first and then decreased in 2009-2016, and the peak of severe cases occurred in eight years in 2011. The onset age of severe HFMD was mainly in 0 ~ 3 years old group, the most of which were scattered children, and the incidence of male children was higher than that of female children. The annual high incidence of severe hand-foot-mouth disease was from June to July 2009-2016. A total of 1,278 severe HFMD cases were reported, accounting for 0.78% of the total cases. The average annual incidence of severe HFMD in 8 years was 50.70 / 1 million. Enterovirus 71 (EV 71) is the main pathogen of hand, foot and mouth disease (HFMD). The time dimension of severe HFMD is from 5 to 7 months. The spatial dimension is mainly distributed in the middle and southwest of Inner Mongolia. Conclusion the incidence of severe hand, foot and mouth disease in Inner Mongolia is spatiotemporal and temporal aggregation, and the intensity of disease is different in different regions. Climate may be the related factor of high incidence of HFMD in Inner Mongolia, and children under the age of 3 years old may be the main affected population. Intensive prevention for younger patients is needed to reduce the incidence of severe cases.
