NEJM:一起专业护理机构新冠聚集性疫情流行病学研究

2020-04-30 MedSci原创 MedSci原创

新冠病毒在这一专业的护理机构中迅速传播,超过一半的阳性感染者在检测时没有症状,无症状人群的防控是有效抑制病毒传播的关键。

专业护理机构是严重急性呼吸综合征冠状病毒2(SARS-CoV-2)疫情的高风险地区。近日研究人员对一专业护理机构中的Covid-19疫情进行了评估。
 
该机构报告1例确诊的新冠肺炎患者,研究人员对所有人员进行了两次连续流行病学调查,间隔1周,在调查中,该机构人员接受了SARS-CoV-2的鼻咽和口咽测试,包括实时逆转录聚合酶链反应(rRT-PCR)、病毒培养和测序。 记录了前14天出现的症状。结果呈阳性的无症状居民在7天后重新评估。SARS-CoV-2感染者可分为典型症状(发热、咳嗽或呼吸急促)、非典型症状、前驱症状或无症状。
 
首例患者首次检测呈阳性23天后,89名居民中有57人(64%)检测出SARS-CoV-2阳性。在参与流行调查的76名居民中,48人(63%)呈阳性。在这48名居民中,27人(56%)在测试时无症状,24人随后出现症状(发病时间中位数,4天)。24名前驱症状患者的rRT-PCR循环阈值中位数为23.1,从17名居民身上发现了活病毒。截至4月3日,在57名感染SARS-CoV-2的居民中,有11人住院(3人在重症监护室),15人死亡(死亡率26%)。
 
研究认为,新冠病毒在这一专业的护理机构中迅速传播,超过一半的阳性感染者在检测时没有症状,无症状人群的防控是有效抑制病毒传播的关键。
