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.
In January 2020, we enrolled a familial cluster of 5 patients with fever and respiratory symptoms who were admitted to the Fifth People’s Hospital of Anyang, Anyang, China, and 1 asymptomatic family member. This study was approved by the local institutional review board, and written informed consent was obtained from all patients. A detailed analysis of patient records was performed.
