目的通过了解北京市西城区手足口病聚集性病例流行特征,为有效预防控制手足口病提供参考。方法现场调查北京市西城区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年报告手足口聚集性病例42起,其中暴发疫情2起。聚集和暴发疫情均主要发生在托幼机构。2010年,西城区44家托幼机构中,有47.73%的托幼机构报告了手足口聚集病例,其中注册园占91.43%。聚集疫情主要发生在5—7月,疾病预防控制部门处理越早,疫情结束越早。密切接触者便标本检测阳性率为30.30%,高于咽拭子标本,差异有统计学意意义(P<0.05)。普通聚集和暴发疫情的病原学分类差异无统计学意义(P>0.05)。结论一些综合性措施能够推迟、减少手足口病在幼儿中的扩散。
Objective To understand the prevalence of hand-foot-mouth disease in Xicheng District, Beijing, and to provide a reference for effective prevention and control of hand-foot-mouth disease.
