Abstract：Objective To investigate and analyze the epidemiological characteristics of a family cluster of COVID-19 in Baoshan District of Shanghai Municipality. Methods Field epidemiological methods were used to investigate the cases and close contacts of a family cluster of COVID-19. The epidemiological data were descriptively analyzed. Real-time fluorescent quantitative RT-PCR was employed to detect 2019-nCov nucleic acid in the specimens collected. Results Eleven persons from families A and B were involved in this family cluster of COVID-19, and 6 of them had attacked, with the incidence rate of 54.55%. The indicator case (A1) of the family cluster had contacted the confirmed cases working at the same unit before the onset of the disease, and then parents (cases A2 and A3) of the case A1 were infected through family life. The case A3 had daily contact with her neighbor B1, resulting in the disease onset in the B1’s family (cases B1, B2 and B3). Conclusions The 2019-nCov was highly infectious and easily spread within families. It is necessary to strengthen the tracing and management of close contacts.
