目的：了解庐江县2013—2014年手足口病（HFMD）聚集性疫情流行特征及危险因素，为制定手足口病防控措施提供科学依据。方法通过国家疾病控制管理系统获得2013—2014年庐江县手足口病疫情信息，并选取发生聚集疫情的幼托机构的儿童及看护人作为研究对象进行问卷调查，统计分析庐江县手足口病聚集性疫情的流行特征及其发病危险因素。结果2013—2014年庐江县手足口病发病率分别为55．37／10万和214．87／10万；共报告手足口病聚集性疫情44起，累计发病例数181例，占同期该病发病总数的6．69％。多因素Logistic回归分析表明，接触手足口患者、看护人手足口病知识缺乏、饭前便后不洗手或很少洗手、有吮咬手指习惯和近一周与儿童公用玩具等5个因素是儿童患手足口病的独立危险因素，其OR值分别是6．518、9．595、10．224、5．642和3．824。结论庐江县手足口病发病受多种因素影响，加强手足口病监测、及时发现聚集性疫情、培养良好的卫生习惯和积极开展健康教育等措施可以预防和减少手足口病的发生。%Objective To explore the epidemic characteristics and risk factors for clustering epidemic of hand foot and mouth disease (HFMD)in Lujiang,2013—2014,and to provide scientific evidence for formulating preventive strategies.Methods The information of epidemic situation of HFMD in Lujiang County was collected from national communicable disease information system,and question-naire survey was conducted among the children and their guardians from the kindergarten in which there was an outbreak of HFMD,and then the epidemic characteristics and risk factors for clustering epidemic of HFMD were analyzed.Results From January 2013 to De-cember 2014,the morbidity of HFMD was 55.37/100 000 and 214.87/100 000,and 44 HFMD outbreaks were reported in Lujiang. The report had a total of 181cases,accounting for 6.69%in total of HFMD.Logistic regression model showed that the history of contact with patients,lower education of guardian,no habit of washing hands before eating and after toilet,habit of sucking fingers and sharing toys with other children within one week were the independent risk factors of HFMD.OR values were 6.518,9.595,10.224,5.642 and 3.824 respectively.Conclusions The HFMD was influenced by many factors,and to prevent and reduce the occurrence of HFMD,we could strengthen the surveillance of HFMD,find the clustering epidemic timely,practice good personal hygiene and imple-ment active health education.
