This study aims to explore the clinical characteristics of the patients with novel coronavirus pneumonia (COVID-19) during rehabilitation. One hundred and twelve confirmed patients were enrolled, while 72 were females (64.3%) and 40 were males (35.7%). The age of the patients was 51.63 ± 4.07 years old. Those patients were divided into mild group, moderate group and severe group based on lesion volume and proportion of total lesion on CT images. The age, gender, past medical history, finger pulse oxygen (SPO2), heart rate (HR) and body temperature and other clinical characteristics of patients were collected. Lesion volume was measured by CT. Compared with mild group, age, lesion volume and total lesion proportion in moderate group were significantly higher. Age, lesion volume and total lesion proportion in severe group were also higher than those in moderate group. Age and past medical history were the risk factors for the lesion volume of COVID-19. Older the patient has larger CT lesion range (R = 0.232, P = 0.045). Without past medical history or combination of post-medical history, the COVID-19 patients had smaller CT lesion ranges, and the history of previous cardiovascular disease and pulmonary disease was important risk factors for the larger CT lesion ranges. The patients who were older or combined with chronic diseases, especially cardiovascular diseases, respiratory disease and diabetes, tended to have the larger lesions. Age and past medical history of patients with COVID-19 period are significantly related to the lesion volume and total lesion proportion on CT images.

本研究旨在探讨新型冠状病毒肺炎（COVID-19）患者康复期间的临床特征。入组112名确诊患者，其中女性72人（64.3%），男性40人（35.7%）。患者年龄为 51.63 ± 4.07 岁。根据CT图像上病灶体积和占病灶总数的比例将患者分为轻度组、中度组和重度组。收集患者的年龄、性别、既往病史、指脉氧（SPO2）、心率（HR）和体温等临床特征。病灶体积通过CT测量。与轻度组相比，中度组年龄、病灶体积和总病灶比例均显着升高。年龄，重度组病灶体积和总病灶比例也高于中度组。年龄和既往病史是 COVID-19 病灶体积的危险因素。年龄较大的患者 CT 病灶范围较大（R  = 0.232，P  = 0.045）。没有既往病史或合并后病史，COVID-19患者的CT病灶范围较小，既往心血管疾病和肺部疾病史是较大CT病灶范围的重要危险因素。年龄较大或合并慢性疾病，尤其是心血管疾病、呼吸系统疾病和糖尿病的患者，往往病灶较大。COVID-19 期患者的年龄和既往病史与 CT 图像上的病灶体积和总病灶比例显着相关。
