Since December 2019, when coronavirus disease 2019 (Covid-19) emerged in Wuhan city and rapidly spread throughout China, data have been needed on the clinical characteristics of the affected patients.
We extracted data regarding 1099 patients with laboratory-confirmed Covid-19 from 552 hospitals in 30 provinces, autonomous regions, and municipalities in mainland China through January 29, 2020. The primary composite end point was admission to an intensive care unit (ICU), the use of mechanical ventilation, or death.
The median age of the patients was 47 years; 41.9% of the patients were female. The primary composite end point occurred in 67 patients (6.1%), including 5.0% who were admitted to the ICU, 2.3% who underwent invasive mechanical ventilation, and 1.4% who died. Only 1.9% of the patients had a history of direct contact with wildlife. Among nonresidents of Wuhan, 72.3% had contact with residents of Wuhan, including 31.3% who had visited the city. The most common symptoms were fever (43.8% on admission and 88.7% during hospitalization) and cough (67.8%). Diarrhea was uncommon (3.8%). The median incubation period was 4 days (interquartile range, 2 to 7). On admission, ground-glass opacity was the most common radiologic finding on chest computed tomography (CT) (56.4%). No radiographic or CT abnormality was found in 157 of 877 patients (17.9%) with nonsevere disease and in 5 of 173 patients (2.9%) with severe disease. Lymphocytopenia was present in 83.2% of the patients on admission.
During the first 2 months of the current outbreak, Covid-19 spread rapidly throughout China and caused varying degrees of illness. Patients often presented without fever, and many did not have abnormal radiologic findings. (Funded by the National Health Commission of China and others.).
自 2019 年 12 月，新型冠状病毒疾病 2019（Covid-19）在武汉市出现并迅速在中国蔓延以来，人们需要了解受影响患者的临床特征。
我们通过 2020 年 1 月 29 日从中国内地 30 个省、自治区和直辖市的 552 家医院中提取了 1099 例实验室确诊的 Covid-19 患者的数据。主要复合终点是入住重症监护病房（ICU）、使用机械通气或死亡。
患者的中位年龄为 47 岁；41.9%的患者为女性。主要复合终点发生在 67 例患者中（6.1%），包括 5.0%入住 ICU，2.3%接受有创机械通气，1.4%死亡。仅有 1.9%的患者有直接接触野生动物的病史。非武汉居民中，72.3%与武汉居民有接触，其中 31.3%曾去过该市。最常见的症状是发热（入院时 43.8%，住院期间 88.7%）和咳嗽（67.8%）。腹泻不常见（3.8%）。中位潜伏期为 4 天（四分位间距，2 至 7）。入院时，胸部 CT 最常见的放射学表现是磨玻璃样混浊（56.4%）。在 877 例非重症疾病患者中有 157 例（17.9%）和 173 例重症疾病患者中有 5 例（2.9%）无放射学或 CT 异常。入院时 83.2%的患者存在淋巴细胞减少。
在当前疫情的前 2 个月内，Covid-19 在全中国迅速传播，并导致不同程度的疾病。患者常无发热，许多患者无异常放射学表现。（由国家卫生健康委员会等资助）。
