In December 2019, cases of pneumonia appeared in Wuhan, China. The etiology of these infections was a novel coronavirus (2019-nCoV),possibly connected to zoonotic or environmental exposure from the seafood market in Wuhan. Human-to-human transmission has accounted for most of the infections, including among health care workers. The virus has spread to different parts of China and at least 26 other countries.1 A high number of men have been infected, and the reported mortality rate has been approximately 2%, which is lower than that reported from other coronavirus epidemics including severe acute respiratory syndrome (SARS; mortality rate, >40% in patients aged >60 years)5 and Middle East respiratory syndrome (MERS; mortality rate, 30%). However, little is known about the clinical manifestations of 2019-nCoV in healthy populations or cases outside Wuhan. We report early clinical features of 13 patients with confirmed 2019-nCoV infection admitted to hospitals in Beijing.
