This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background:
Outbreak of COVID-19 has brought catastrophe to huge numbers of families. However, even though numerous tragedies occurred, there were few reports about family cluster infection in the academic journals.Methods:
The electronic medical records of 10 COVID-19 patients in a big family were retrospectively reviewed and analyzed.Results:
These 10 patients, 4 males and 6 females, were infected through two successive family feasts during Spring Festival. The infection source was a family member at asymptomatic state, who lived in Hubei but travelled to Nanjing. The median age of these 10 patients was 61.5, with the oldest 95 and youngest 38. The incubation period varied from 3 to 17 days, with the median of 5.5. Of them, 2 patients were asymptomatic. The most common symptoms at onset were fever (6/10) and dry cough (6/10). All of them displayed lesions on the chest CT. 40% of them had leukopenia, neutropenia and lymphopenia. After anti-virus treatment, all the patients significantly improved and were discharged.Conclusions:
SARS-Cov-2 was highly contagious and so crafty that a varied incubation period did exist. Part of patients might be asymptomatic, which was the potential source of transmission. More measures for protection or quarantine should be taken at home if family member had travel history nearby the epidemic area. Keywords COVID-19, SARS-Cov-2, family cluster, asymptomatic, incubation period.
