 The 2019 novel coronavirus, 2019-NCoV, has caused an outbreak of pneumonia in Wuhan, Hubei Province, China since late December 2019. This study investigated the epidemiological history, clinical characteristics, treatment regimes, and prognosis of patients infected with 2019-NCoV during this outbreak. The majority of patients presented with fever as the first symptom, and most of them still showed typical manifestations of viral pneumonia on chest imaging. Middle-aged and elderly patients with underlying comorbidities were more likely to develop respiratory failure and have a worse prognosis.
