Abstract Objectives: A pneumonia associated with 2019 novel coronavirus (2019-nCoV, subsequently named SARS-CoV2) emerged worldwide since December, 2019. We aimed to describe the epidemiological characteristics of 2019 coronavirus disease (COVID-19) in Shaanxi province of China. Results: 1. Among the 245 patients, 132 (53.9%) were males and 113 (46.1%) were females. The average age was 46.15 ± 16.43 years, ranging from 3 to 89 years. 2. For the clinical type, 1.63% (4/245) patients were mild type, 84.90% (208/245) were moderate type, 7.76% (19/245) were severe type, 5.31% (13/245) were critical type and only 0.41% (1/245) was asymptomatic. 3. Of the 245 patients, 116 (47.35%) were input case, 114 (46.53%) were non-input case, and 15 (6.12%) were unknown exposure. 4. 48.57% (119/245) cases were family cluster, involving 42 families. The most common pattern of COVID-19 family cluster was between husband and wife or between parents and children. Keywords: SARS-CoV2, COVID-19, Epidemiological features, Family cluster Introduction Since late December 2019, a novel coronavirus disease, later named COVID-19 by World Health Organization (WHO), has emerged in Wuhan, China [1–3], and then spread to other provinces in China and the world. As of July 17, 2020, nearly 13,810,534 confirmed cases and 590,005 death cases have been reported in almost all countries and territories.

Wuhan city has been closed since January 23, 2020, in the following 2 days, the Chinese government mobilized all forces to stop the epidemic, including the suspension of public transport, subway, ferry and long-distance passenger transport, and the temporary closure of airports and trains. Shaanxi is located in the northwest of China, bordering Wuhan in the southeast, covering an area of 205,800 square kilometers, with 10 cities and a permanent population of 38.64 million. It is very important to understand the epidemiological characteristics of COVID-19 transmission outside Wuhan for the effective control strategies. During major infectious disease outbreaks, quarantine always be the necessary preventive measure, but experience about COVID-19 pandemic is limited. During t
