BMJ:冰岛2019新冠肺炎患者临床特征研究

2020-12-06 MedSci原创 MedSci原创

在冰岛广泛的新冠肺炎核酸筛查过程中,大多数SARS-CoV-2阳性人群仅有轻微症状,发烧和呼吸困难的患者比例较低

由于人口相对少,而且相对封闭,加之感染人数众多,冰岛已成为新冠肺炎流行趋势研究的最佳范本之一。近日研究人员就冰岛新冠肺炎(covid-19)疫情的特征进行了考察。
 
在2020年3月17日至4月30日期间,所有通过逆转录聚合酶链反应(RT-PCR)检测严重急性呼吸综合征冠状病毒2(SARS-Cov-2)阳性的感染者参与研究,病例有3个来源:基于临床疑似症状进行的靶向检测、基于自我转诊的公开筛查和随机人群筛查。 所有已确定的病例都被纳入远程健康监测网络,并从诊断到恢复期间的患者症状进行系统监测。研究的主要终点为随访期间患者出现19个预先定义的症状中的一个或多个。
 
在1564名核酸检测阳性的患者中,最常见的新冠肺炎症状包括肌痛(55%)、头痛(51%)和干咳(49%)。在确诊时,83人(5.3%)报告没有症状,其中49人(59%)在随访期间仍无症状。在确诊时,216人(14%)和349人(22%)分别不符合疾病控制和预防中心(CDC)和世界卫生组织(WHO)的新冠肺炎病例定义。大多数(67%)的SARS-CoV-2阳性患者在整个疾病过程中都仅有轻微的症状。
