To analyze the global epidemic status of the Ebola virus disease (EVD) and assess the importation risk into China.
Data from World Health Organization reports were used. We described the global epidemic status of EVD from 1976-2021, and assessed and ranked the importation risk of EVD from the disease-outbreaking countries into China using the risk matrix and Borda count methods, respectively.
From 1976-2021, EVD mainly occurred in western and central Africa, with the highest cumulative number of cases (14,124 cases) in Sierra Leone, and the highest cumulative fatality rate (85%) in the Congo. Outbreaks of EVD have occurred in the Democratic Republic of the Congo and Guinea since 2018. The importation risk into China varies across countries with outbreaks of disease. The Democratic Republic of the Congo had an extremely high risk (23 Borda points), followed by Guinea and Liberia. Countries with a moderate importation risk were Nigeria, Uganda, Congo, Sierra Leone, Mali, and Gabon, while countries with a low importation risk included Sudan, Senegal, and Cte d'Ivoire.
China is under the risk of EVD importation with the globalization and severe epidemic status of EVD. Key attention need to be paid to the Democratic Republic of the Congo, Guinea, and Liberia. Therefore, it is necessary to prevent and prepare in advance for importation risk in China.
分析埃博拉病毒病（EVD）的全球流行状况并评估其传入中国的风险。
使用世界卫生组织报告中的数据。我们描述了1976 - 2021年EVD的全球流行状况，并分别使用风险矩阵和博尔达计数法评估了EVD从疾病暴发国家传入中国的风险并进行排名。
1976 - 2021年，EVD主要发生在非洲西部和中部，病例累计数最高的是塞拉利昂（14,124例），病死率累计最高的是刚果（85%）。自2018年以来，刚果民主共和国和几内亚均出现了EVD疫情。EVD传入中国的风险因疾病暴发国家而异。刚果民主共和国的风险极高（23个博尔达分），其次是几内亚和利比里亚。传入风险中等的国家有尼日利亚、乌干达、刚果、塞拉利昂、马里和加蓬，而传入风险低的国家包括苏丹、塞内加尔和科特迪瓦。
随着EVD的全球化和严峻的流行态势，中国面临EVD传入风险。需重点关注刚果民主共和国、几内亚和利比里亚。因此，有必要对中国的传入风险提前做好预防和准备。
