Abstract

Objective To study the clinical characteristics of 2019 coronavirus (2019-nCoV) pneumonia patients and make a feasible screening process in fever clinic. Methods Epidemiologic features, clinical presentation, laboratory findings and image features of the screened patients were retrospectively collected and analyzed. Results Totally, 46 patients were screened, 9 of them were laboratory-confirmed 2019-nCoV infection, and others were defined as laboratory-excluded patients. Laboratory-confirmed patients had higher frequency of travelling or residence in Wuhan within two weeks of onset (P 0.05). The most common feature of the laboratory-confirmed patients was fever (100%), but the symptoms showed no differences between the two groups (P>0.05). Laboratory-confirmed patients had lower white blood cell count than the laboratory-excluded patients (P<0.05), and all of them had pneumonia in chest CT scan. None of the patients with normal chest CT had positive 2019-nCoV nucleic acid test. Conclusions No specific symptom was helpful in the diagnosis of 2019-nCoV infection. However, patients without chest CT scan changes had a very low risk of 2019-nCoV infection despite of the epidemiologic history and fever. We recommended a screening procedure that might be helpful to reduce the rate of miss diagnosis and improve screening efficiency. Key words: 2019-nCoV; pneumonia; fever; chest CT

2019年新型冠状病毒感染患者的临床特征及可行的筛查程序/中华急诊医学杂志

目的了解新型冠状病毒肺炎（2019-nCoV）患者的临床特点，为发热门诊筛查提供可行的方法。方法回顾性分析筛查患者的流行病学特征、临床表现、实验室检查结果和影像学特征。结果共筛查46例患者，其中9例为实验室确诊的2019-nCoV感染者，其余为实验室排除患者。实验室确诊患者在发病两周内有较高的武汉旅行或居住频率（P＜0.05）。实验室确诊患者最常见的特征是发烧（100%），但两组症状无差异（P＞0.05），胸部CT扫描均为肺炎。胸部CT正常的患者中没有一例2019-nCoV核酸检测呈阳性。结论无特异性症状有助于诊断2019-nCoV感染。然而，尽管有流行病学史和发烧，但没有胸部CT扫描改变的患者感染2019-nCoV的风险非常低。我们推荐了一种可能有助于降低漏诊率和提高筛查效率的筛查程序。关键词：2019-nCoV；肺炎；发烧；胸部CT
