Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) is continuously and rapidly circulating at present. Asymptomatic patients have been proven to be contagious and thus pose a significant infection control challenge. Here we describe the characteristics of asymptomatic patients with SARS-CoV-2 infection in Jinan, Shandong province, China. A total of 47 patients with confirmed COVID-19 were recruited. Among them, 11 patients were categorized as asymptomatic cases. We found that the asymptomatic patients in Jinan were relatively young and were mainly clustered cases. The laboratory indicators and lung lesion on chest CT were mild. No special factors were found accounting for the presence or absence of symptoms. The presence of asymptomatic patients increased the difficulty of screening. It is necessary to strengthen the identification of such patients in the future.
新型冠状病毒病（COVID-19）由严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）引起，目前正在持续快速传播。无症状患者已被证明具有传染性，因此对感染控制构成重大挑战。在这里，我们描述了中国山东省济南市 SARS-CoV-2 感染无症状患者的特征。共招募了 47 名确诊 COVID-19 的患者。其中，11 例患者被归类为无症状病例。我们发现，济南市的无症状患者相对年轻，主要是聚集性病例。实验室指标和胸部 CT 上的肺部病变较轻。未发现特殊因素导致症状的出现或不存在。无症状患者的存在增加了筛查的难度。在未来有必要加强对这类患者的识别。
