目的通过对2010—2013年托幼机构手足口病聚集性发病特点进行分析,为托幼机构手足口病防控提供依据。方法收集2010—2013年托幼机构手足口病聚集性疫情相关资料,采用描述性流行病学方法进行分析。结果 2010—2013年天津市河北区共发生托幼机构手足口病聚集84起,聚集性病例人数376人。聚集性疫情2个高峰分别在6月和11月;部分卫生条件较差的区域手足口聚集疫情起数较多;手足口聚集性病例的发生与年龄呈负相关;实验室检测显示手足口病的聚集疫情多由EV 71、Cox A16病毒引起。结论托幼机构是手足口病易感人群集中的单位,容易形成聚集,是手足口病防控的重点场所。
OBJECTIVE: To analyze the characteristics of aggregated onset HFMD in kindergartens and nurseries in 2010-2013 so as to provide a basis for the prevention and control of hand-foot-mouth disease in kindergartens and nurseries. Methods The data of aggregated outbreaks of hand-foot-mouth disease in kindergartens and nurseries were collected from 2010 to 2013 and analyzed by descriptive epidemiological method. Results In 2010-2013, a total of 84 HFMD cases were found in kindergartens and nurseries in Hebei District of Tianjin. The number of cases was 376. The two peaked in June and November respectively. In some areas with poor sanitary conditions, there were more outbreaks of hand-foot-mouth aggregation. The incidence of hand-foot-mouth aggregation was negatively correlated with age. Laboratory tests showed hand-foot-mouth disease The majority of the outbreaks were caused by EV 71 and Cox A16 viruses. Conclusion The nursery-child care unit is a concentrated unit of hand, foot and mouth disease susceptible people, and it is easy to form aggregation. It is the key place for prevention and control of hand, foot and mouth disease.
