摘要
目的分析天津市河北区2014—2018年手足口病聚集性疫情流行病学特点,为手足口病聚集性疫情防治工作提供科学依据。方法收集手足口病聚集性疫情资料,采用描述流行病学方法和SPSS 16.0统计软件对流行病学及病原特征进行分析,计数资料比较采用χ^2检验。结果天津市河北区2014—2018年共报告手足口病聚集性疫情125起,涉及病例518例,波及3 290人;聚集性疫情发病高峰在5~6月,次高峰为9月;聚集发生地点以托幼机构为主,占67.20%,托幼机构的聚集疫情总数比家庭和学校高,差异有统计学意义(χ^2=31.471,P<0.01);3~5岁为高发年龄段;发现途径以区疾控中心经监测疾病信息系统发现为主,占62.40%;共采集86起手足口病聚集性疫情相关样本进行检测,病原型别以CoxA 6和CoxA 16为主,高于EV71和其他肠道病毒,差异有统计学意义(χ^2=18.919,P<0.05)。结论托幼机构是手足口病聚集性疫情的重点场所,学校主动报告率有待提高。
Objective To analyze the epidemiological features of hand-food-mouth disease(HFMD)clustered cases in Hebei District of Tianjin from 2014 to 2018, in order to provide scientific evidence for clustered cases control and prevention.Methods The epidemic data of HFMD clustered cases were collected to analyze the epidemiological and etiological features by descriptive epidemiological method and SPSS16.0 software, the enumeration data were compared with chi-square test.Results A total of 125 clustered incidents with 518 cases out of 3290 close contacts were reported in Hebei District of Tianjin from 2014 to 2018;the peak time of outbreaks was concentrated from May to June, and the second peak was September;about 67.20% of the clustered cases happened in kindergartens, higher than in households and schools, the difference was statistically significant(χ^2=31.471, P<0.01);most cases were occurred among children aged from 3 years old to 5 years old;most clustered cases(62.40%) were reported by disease surveillance information system of district center for disease control and prevention. A total of 86 related samples of HFMD clustered cases were collected for detection. The major pathogenic types were CoxA 6 and CoxA 16, which were higher than EV71 and other enterovirus, and the difference was statistically significant(χ^2=18.919, P<0.05).Conclusion Kindergartens are the key location of HFMD clustered cases, the positive reporting rate of schools need to be improved.
