Affected patients were geographically linked with a local wet market as a potential source. No data on person-to-person or nosocomial transmission have been published to date.<h4>Methods</h4>In this study, we report the epidemiological, clinical, laboratory, radiological, and microbiological findings of five patients in a family cluster who presented with unexplained pneumonia after returning to Shenzhen, Guangdong province, China, after a visit to Wuhan, and an additional family member who did not travel to Wuhan. Phylogenetic analysis of genetic sequences from these patients were done.<h4>Findings</h4>From Jan 10, 2020, we enrolled a family of six patLancet (London, England)514-523https://www.ebi.ac.uk/biostudies/studies/S-EPMC7159286biostudies-literatureA familial cluster of pneumonia associated with the 2019 novel coronavirus indicating person-to-person transmission: a study of a family cluster.PMC7159286Cai JPYuan SYang JLiu JTsoi HWChan WMChan JFChan KHIp JDChen HPoon RWHui CKLo SKXing FTo KKChu HCheng VCYip CCYuen KYPoon VKKok KHfalseA familial cluster of pneumonia associated with the 2019 novel coronavirus indicating person-to-person transmission: a study of a family cluster.<h4>Background</h4>An ongoing outbreak of pneumonia associated with a novel coronavirus was reported in Wuhan city, Hubei province, China.
