The patients confirmed with NCP in Shaanxi Province are mainly have the history of Wuhan contact, There are characteristics of family aggregation and concealment.

in Ankang. There are 539 suspected cases in the all province.The main confirmed cases of early stage are mainly imported cases. ( Fig.1b. This study, to our knowledge is the largest case series to date of confirmed patients with 2019-nCoV infection. Besides, this is the first study focus on the 2019-nCoV outside Wuhan. We found that the majority of patients were middle-aged men. This result is consistent with the research of Zhong NS in Wuhan [6] . They found that the median age of patients with 2019-nCoV infection was 47.0 years, and 58.1% were males. We also consistent with the study of Huang C. who also concluded that the majority of infected patients were men (73%) [7] . We further divided patients with NCP into With Wuhan exposure group and without Wuhan exposure group. We founded that patients without Wuhan explore history were older than those with Wuhan explore history, and the difference was statistically significant. This may be due to the fact that most of the patients with 2019-nCoV infection in Shaanxi are imported cases, and most of them are migrant workers in Hubei and returned hometown during the Spring Festival. In addition, older people are more likely to be infected with 2019-nCoV. Furthermore, the day from onset to diagnosis for patients with Wuhan exposure history is longer than that without Wuhan. This is easy to understand, because most of the patients without Wuhan exposure are infected by imported patients. Wuhan exposure group was further divided into long-term exposure group and short-term exposure group. The conclusion were that the male Ma.X. made substantial contribution to analysis and interpretation of the work;

Yang.M. helped with access to the data, data management, and analysis; Wang.S.Y made substantial contributions to the conception of the work, revising the draft for important intellectual content, and agreed to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
