To analyze the characteristics of COVID-19 case spectrum and spread intensity in different provinces in China except Hubei province. The daily incidence data and case information of COVID-19 were collected from the official websites of provincial and municipal health commissions. The morbidity rate, severity rate, case-fatality rate, and spread ratio of COVID-19 were calculated. As of 20 March, 2020, a total of 12 941 cases of COVID-19 had been conformed, including 116 deaths, and the average morbidity rate, severity rate and case-fatality rate were 0.97/100 000, 13.5 and 0.90, respectively. The morbidity rates in Zhejiang (2.12/100 000), Jiangxi (2.01/100 000) and Beijing (1.93/100 000) ranked top three. The characteristics of COVID-19 case spectrum varied from province to province. The first three provinces (autonomous region, municipality) with high severity rates were Tianjin (45.6), Xinjiang (35.5) and Heilongjiang (29.5). The case-fatality rate was highest in Xinjiang (3.95), followed by Hainan (3.57) and Heilongjiang (2.70). The average spread ratio was 0.98 and the spread intensity varied from province to province. Tibet had the lowest spread ratio (0), followed by Qinghai (0.20) and Guangdong (0.23). The intervention measures were effective in preventing the spread of COVID-19 and improved treatment effect in China. However, there were significant differences among different regions in severity, case-fatality rate and spread ratio.
分析中国除湖北省外不同省份新冠疫情病例谱特征及传播强度。从各省及直辖市卫生健康委员会官方网站收集新冠疫情每日发病数据及病例信息，计算新冠发病率、重症率、病死率及传播比。截至2020年3月20日，共确诊新冠病例12941例，其中死亡116例，平均发病率、重症率及病死率分别为0.97/10万、13.5及0.90。发病率居前三位的省份为浙江（2.12/10万）、江西（2.01/10万）和北京（1.93/10万）。新冠病例谱特征因省而异。重症率居前三位的省（自治区、直辖市）为天津（45.6）、新疆（35.5）和黑龙江（29.5）。病死率最高的是新疆（3.95），其次是海南（3.57）和黑龙江（2.70）。平均传播比为0.98，传播强度因省而异。西藏传播比最低（0），其次是青海（0.20）和广东（0.23）。中国采取的干预措施有效预防了新冠疫情传播并提高了治疗效果。然而，不同地区在重症率、病死率及传播比方面存在显著差异。
