A novel coronavirus has resulted in an ongoing outbreak of viral pneumonia in China.1-3 Person-to-person transmission has been demonstrated,1 but, to our knowledge, transmission of the novel coronavirus that causes coronavirus disease 2019 (COVID-19) from an asymptomatic carrier with normal chest computed tomography (CT) findings has not been reported.
