Chan JFW, Yuan S, Kok KH, et al. - A study of a family cluster was designed to report the epidemiological, clinical, laboratory, radiological, and microbiological findings of five individuals 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. Researchers performed a phylogenetic analysis of genetic sequences from these patients. A family of six individuals who traveled to Wuhan from Shenzhen between Dec 29, 2019, and Jan 4, 2020, were included. The results of this study displayed that the findings are compatible with person-to-person transmission of this novel coronavirus in hospital and family settings, and the reports of infected travelers in other geographical regions.
