Data were obtained from 3 hospitals in Beijing, China (Beijing Tsinghua Changgung Hospital, School of Medicine, Tsinghua University [8 patients], Beijing Anzhen Hospital, Capital Medical University [4 patients], and College of Respiratory and Critical Care Medicine, Chinese PLA General Hospital [1 patient]). Patients were hospitalized from January 16, 2020, to January 29, 2020, with final follow-up for this report on February 4, 2020. Patients with possible 2019-nCoV were admitted and quarantined, and throat swab samples were collected and sent to the Chinese Center for Disease Control and Prevention for detection of 2019-nCoV using a quantitative polymerase chain reaction assay.3 Chest radiography or computed tomography was performed. Data were obtained as part of standard care. Patients were transferred to a specialized hospital after diagnosis. This study was approved by the ethics commissions of the 3 hospitals, with a waiver of informed consent.
The median age of the patients was 34 years (25th-75th percentile, 34-48 years); 2 patients were children (aged 2 years and 15 years), and 10 (77%) were male. Twelve patients either visited Wuhan, including a family (parents and son), or had family members (grandparents of the 2-year-old child) who visited Wuhan after the onset of the 2019-nCoV epidemic (mean stay, 2.5 days). One patient did not have any known contact with Wuhan.
Twelve patients reported fever (mean, 1.6 days) before hospitalization. Symptoms included cough (46.3%), upper airway congestion (61.5%), myalgia (23.1%), and headache (23.1%) (Table). No patient required respiratory support before being transferred to the specialty hospital after a mean of 2 days. The youngest patient (aged 2 years) had intermittent fever for 1 week and persistent cough for 13 days before 2019-nCoV diagnosis. Levels of inflammatory markers such as C-reactive protein were elevated, and numbers of lymphocytes were marginally elevated (Table).
Four patients had chest radiographs and 9 had computed tomography. Five images did not demonstrate any consolidation or scarring. One chest radiograph demonstrated scattered opacities in the left lower lung; in 6 patients, ground glass opacity was observed in the right or both lungs (Figure). As of February 4, 2020, all the patients recovered, but 12 were still being quarantined in the hospital.
