2010年北京市手足口病聚集性病例流行病学分析

Epidemiological analysis on cluster cases of hand-foot-mouth disease in Beijing, 2010

目的了解北京市手足口病聚集性病例流行特征，为有效防控手足口病提供参考。方法现场调查北京市2010年手足口病聚集性病例基本情况，应用描述流行病学方法进行分析。结果2010年北京市报告手足口聚集性病例1350起，暴发疫情81起。聚集和暴发疫情均主要发生在托幼机构。2010年35．86％的幼儿园报告了手足口病聚集，距离市中心近的幼儿园发生聚集比例更高。聚集全年均有报告，疾控部门介入越早，疫情结束越早。近郊区幼儿感染手足口病平均年龄最小。普通聚集和暴发疫情的病原学分类无统计学差异。结论一些综合性措施能够推迟、减少甚至杜绝手足口病在幼儿中的蔓延。故应着力于抓好日常防控，从根本上减少发病和暴发。

Objective The present study was conducted to gain insight into the epidemic characteristics of hand-foot-mouth disease cluster cases in Beijing, 2010, so as to provide reference data for prevention and control of hand-food-mouth disease. Methods Analysis was made on the data of hand-food-mouth disease cluster cases in Beijing in 2010, and descriptive epidemiology was used to analyze the data. Results A total of 1350 hand-food-mouth disease cluster cases and 81 outbreaks were reported in Beijing in 2010. Both the cluster cases and outbreaks occurred mainly in kindergartens, and 35.86% kindergartens reported cluster cases in 2010. More cluster cases were found near the city center. Cluster cases could be found in all seasons, and lasted shorter with early prevention and control measures. Infected children lived near the city center were younger than other areas. The pathogenic distribution of ordinary cluster cases and the outbreaks was coincident. Conclusion Some comprehensive measures can postpone, decrease, and even stop the spread of hand-food-mouth disease in children Better implementations of routine prevention and control measures should be. taken to reduce the number of cases and outbreaks.
