| 目的 了解陕西省新型冠状病毒肺炎（COVID-19）的发病趋势及流行特征。方法 收集陕西省截至2020年2月22日COVID-19的疫情数据，进行流行病学描述性分析。结果 陕西省共报告245例COVID-19确诊病例，全省累积报告的确诊病例以轻型、普通型为主（87.76%），随着时间的推移，出现确诊病例的地区不断扩大，以西安市报告病例数最多（占全省报告总病例数近一半）。陕西省由输入型病例逐渐转为本地病例为主，而本地病例的传播途径主要以家庭聚集性传播为主。陕西省不同来源确诊病例均造成了二代病例传播。2月7日之后报告病例数开始波动下降并逐渐趋于平稳，目前陕西省疫情发展处于归零期。结论 陕西省的总体疫情形势已趋向缓和，但考虑到复工返学的到来，同时随着境外输入病例的不断增加，防控工作将面临新的挑战。 |

| Objective To understand the incidence trend and epidemiological characteristics of COVID-19 in Shaanxi province. Methods The incidence data of COVID-19 reported in Shaanxi as of 22 February, 2020 were collected for an epidemiological descriptive analysis. Results A total of 245 confirmed cases of COVID-19 were reported in Shaanxi. Most cases were mild (87.76%). As time passed, the areas where confirmed cases were reported continued to increase. The case number in Xi'an was highest, accounting for nearly half of the total reported cases in the province. The epidemic pattern in Shaanxi had gradually shifted from imported case pattern to local case pattern, and the transmission of local cases was mainly based on family cluster transmission. The confirmed cases from different sources had caused the secondary transmission in Shaanxi. After February 7, the number of reported cases began to fluctuate and decrease stably, indicating a decrease-to-zero period. Conclusions At present, the overall epidemic of COVID-19 in Shaanxi has gradually been mitigated. However, considering the approaching of return to work and study and the increasing of imported cases from other countries, the prevention and control of COVIS-19 in Shaanxi will face new challenges. |
