Abstract

We report epidemiologic, laboratory, and clinical findings for 7 patients with 2019 novel coronavirus disease in a 2-family cluster. Our study confirms asymptomatic and human-to-human transmission through close contacts in familial and hospital settings. These findings might also serve as a practical reference for clinical diagnosis and medical treatment.

Keywords: 2019 novel coronavirus disease; COVID-19; China; SARS-CoV-2; Xuzhou; asymptomatic transmission; close contact; familial cluster; nosocomial transmission; respiratory infections; severe acute respiratory syndrome coronavirus 2; viruses; zoonoses.
