摘要
目的对一起医院内流行性感冒(流感)暴发进行调查和处置,为医院流感暴发的预防与控制提供参考。方法 2014年7月29日—8月7日某院神经外科出现8例流感样感染者,对其进行流行病学调查,采集患者咽拭子标本进行实验室检测。结果 8例感染者中神经外科医务人员6例,医务人员家属和患者各1例,感染者症状以低热、咽痛、全身乏力为主。该科室共有患者及医务人员67例,流行性感冒罹患率为11.94%,同期医院其他科室无类似感染者。6例感染医务人员咽拭子检测结果为季节性H3型流感病毒核酸阳性。医院感染管理办公室介入调查,神经外科积极进行隔离与抗病毒治疗,暴发得到有效控制。结论此起医院感染暴发为季节性H3型流感暴发,医院在开启中央空调时应加强病室开窗通风及环境消毒,同时流感流行季节应对医务人员进行流感疫苗接种,加强监测,预防医院内流感暴发。
