【摘要】：目的探讨北京市通州区某小学一起腺病毒3型感染暴发疫情的流行病学特征和发生原因,为类似疫情防控提供技术支持。方法采用统一的流行病学个案调查表进行现场调查,制定病例定义,描述流行特征;采集患者咽拭子,采用反转录-聚合酶链反应(RT-PCR)技术确定致病原。结果 2015年11月4—17日累计发现病例34例,无重症和死亡病例。咽拭子标本检测确认为腺病毒3型感染,其临床特征主要表现为发热(100.00%)为主,伴有咳嗽(64.71%)、头痛(32.35%)、咽痛(23.53%)等症状。结论该疫情是由腺病毒3型引起的学校呼吸道感染暴发疫情,时空分布呈现明显聚集性,传播途径可能以呼吸道飞沫和密切接触传播为主,首发病例发病后晨午检未发现继续上课是造成这次暴发的主要原因之一,建议学校应严格执行晨午检制度和做好教室通风和消毒工作。
