目的了解国外新型冠状病毒肺炎的发病现状和趋势。
方法收集国外2020年1月20日—2020年2月18日的新型冠状病毒肺炎的确诊病例数据,按年龄、性别、国籍、接触史、地区、国家进行分层分析和发病时间趋势分析。
结果1月20日—2月18日期间,国外累计确诊病例数804例,除去日本"钻石公主号"邮轮上的454例,每日新增病例数波动性较大,呈现出先上升,后保持平稳波动的趋势,新增病例最高点日期为2月1日,发病例数为26。确诊病例主要集中于亚洲国家,但在欧洲、北美洲、大洋洲和非洲地区也有分布。截至2月15日,发现确诊病例国家数达到25后再无增加,其中新加坡、日本和泰国是发病病例数最多的国家,例数分别为77、65和35。在可收集到基本信息的确诊病例中,有相关确诊病例接触史的病例多于具有湖北居住或旅行史的确诊病例,而且非中国国籍、40岁及以上和男性较多。
结论新型冠状病毒在国外已传播,而且产生第二代病例,发病人数少,但发病趋势波动大,需警惕病毒进一步加大扩散的可能。
ObjectiveTo learn about the current situation and trends of novel coronavirus diseases 2019 (COVID-2019) in foreign countries.
MethodsThe data on confirmed COVID-2019 cases were collected between January 20, 2020 and February 18, 2020 and by age, sex, nationality, contact history, region, and country were performed stratified analysis and onset time analysis.
ResultsFrom January 20th to February 18th, the cumulative number of confirmed cases of COVI D-2019 abroad was 804. Excluding the 454 cases on the "Diamond Princess" cruise ship in Japan, the daily number of new cases fluctuated, showed a trend of rising first and then maintaining a steady trend. The peak date for new cases was on February 1, with the number of cases reaching 26. The confirmed cases were mainly concentrated in Asian countries, but also distributed in Europe, North America, Oceania and Africa. As of February 15, there was no more increase reported in the number of countries where confirmed cases occurred after reaching 25. Among these countries, Singapore, Japan, and Thailand were with the highest number of cases, with 77, 65, and 35 cases, respectively. In accordamce to available information on confirmed cases, the cases with history of exposure to confirmed cases were more than those with history of living or traveling in Hubei. And more cases were non-Chinese nationalities, 40 years old and above, and males .
ConclusionThe novel coronavirus has transmitted abroad, and produced second-generation cases. Although the incidence is low abroad , its trend fluctuates greatly, so sufficient attention must be paid to the possibility of further transmission.
