摘要
目的通过对内江市市中区首例新型冠状病毒肺炎病例引发聚集性疫情的调查分析,探讨其传播规律和流行特征。方法按照国家卫生健康委《新型冠状病毒感染的肺炎防控方案(第3版)》中的流行病学调查方案,通过查阅病历并结合现场流行病学调查,描述该事件发生发展及感染传播过程,分析疫情的流行病学特征。采集患者急性期呼吸道标本,采用Real-time RT-PCR方法检测新冠病毒核酸。结果市中区首例患者男性36岁,2020-01-29出现发热、干咳症状,鼻、咽拭子新冠病毒核酸检测阳性。在与患者接触的人员中共检出发现4例确诊病例,其余密切接触者目前未出现症状。结论该起疫情为内江市中区首例新冠肺炎病例引发的聚集性疫情,提示应加强对确诊病例和无症状感染者的密切接触者的早期新冠病毒核酸检测,同时增加对可疑病例的胸部影像学检查,减少误诊和漏诊。
