目的了解合肥市手足口病聚集性发病流行特征,探讨幼托机构手足口病聚集性发病危险因素,为制定重点场所和重点人群防控措施提供依据。方法现场调查合肥市2012年手足口病聚集性发病情况,随机抽取60家发生聚集性疫情的幼托机构,采用病例对照的方法抽取同时期未发生聚集性疫情的60家幼托机构,探讨手足口病发生聚集性疫情的危险因素。结果全年共发生220起聚集性疫情,其中210起发生在幼儿园,其余10起发生在家庭和社区。手足口病高发期间,聚集性病例未及时隔离,户外组合玩具数量多,住宿房间拥挤,托幼机构教师防治知识知晓率低对手足口病聚集性疫情发生有促进作用。疾控部门对聚集性疫情采取防控措施早,疫情规模越小。结论落实手足口病综合防治措施能够推迟、减少甚至杜绝手足口病在托幼机构中的蔓延。
Objective To understand the epidemiological characteristics of HFMD in Hefei and to explore the risk factors of HFMD in SVTC, so as to provide basis for the prevention and control measures of key sites and key populations. Methods The incidence of hand-foot-mouth disease in Hefei city in 2012 was surveyed. Sixty kindergartens with aggregated outbreaks were randomly selected. Sixty kindergartens with no aggregated outbreak in the same period were selected for case-control study. Risk factors for the buildup epidemic in mouth disease. As a result, there were a total of 220 ancillary outbreaks throughout the year, 210 of them in kindergartens and the remaining 10 in families and communities. In the period of HFMD, clustering cases were not isolated in time. The number of outdoor combination toys, crowded accommodation rooms, awareness rate of teachers in nursery schools with low awareness of prevention and treatment of foot and mouth disease had a positive effect on the aggregation of outbreaks of HFMD. Disease control departments to take preventive measures to control the epidemic early, the smaller the scale of the outbreak. Conclusion The implementation of comprehensive prevention and control measures of HFMD can delay, reduce or even eliminate the spread of HFMD in nurseries.
