自2020年1月20日国内出现首例新型冠状病毒（2019- ncov）确诊病例以来，仅过了20多天，确诊病例就达到28例。其中男性15例（53.6%），中位年龄42岁（20 ~ 73岁）。确诊病例中，指数型16例（57.2%）、第一代9例（32.1%）、第二代3例（10.7%）。第一代和第二代患者均为指示病例的家庭成员或亲密接触者。16名指标患者中，有15人是1月19日~ 24日入境的，1人是1月31日入境的。平均潜伏期为3.9天（中位数为3.0天），估计繁殖数为0.48。确诊患者中有3人在确诊时无症状。流行病学指标将随着今后获得更多数据而修订。在世界各地的研究人员之间分享流行病学信息对于有效地准备和应对这一新的传染病至关重要。
In about 20 days since the diagnosis of the first case of the 2019 novel coronavirus (2019-nCoV) in Korea on January 20, 2020, 28 cases have been confirmed. Fifteen patients (53.6%) of them were male and median age of was 42 years (range, 20-73). Of the confirmed cases, 16, 9, and 3 were index (57.2%), first-generation (32.1%), and second-generation (10.7%) cases, respectively. All first-generation and second-generation patients were family members or intimate acquaintances of the index cases with close contacts. Fifteen among 16 index patients had entered Korea from January 19 to 24, 2020 while 1 patient had entered Korea on January 31, 2020.The average incubation period was 3.9 days (median, 3.0), and the reproduction number was estimated as 0.48. Three of the confirmed patients were asymptomatic when they were diagnosed. Epidemiological indicators will be revised with the availability of additional data in the future. Sharing epidemiological information among researchers worldwide is essential for efficient preparation and response in tackling this new infectious disease.
