新冠肺炎的流行病学、传播动力学、疫苗和非药物性干预措施评价的研究进展

Research Progress on Epidemiology,Transmission Dynamics,Vaccination,and Non-pharmaceutical Intervention Evaluation of COVID-19

在全球新冠肺炎持续流行、病毒变异频发的背景下,我国长期面临境外输入和本土反弹的双重压力。自新冠肺炎疫情初始,在国家自然科学基金委员会的支持下,复旦大学余宏杰研究团队运用经典流行病学、传染病学、统计学、地理信息学和生态学等多学科交叉技术,通过临床评价、构建基于群体和个体水平的传播动力学模型等,在疫情的各个阶段针对新冠肺炎的流行病学、传播动力学、疫苗和非药物性干预措施评价等领域开展了深入、系统的研究,为建立新冠肺炎流行病学特征的认识奠定了科学基础,为疫情防控、推进复工复产、制定疫苗免疫策略等提供了直接科学证据。

In the context of ongoing global pandemic of coronavirus disease 2019(COVID-19)and frequent mutations of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),China faces pressures of both international imported COVID-19 cases and local outbreaks for a long time.Since the beginning of COVID-19 pandemic,with the support of the National Natural Science Foundation of China(NSFC),Yu Hongjie team from Fudan University have conducted systematic studies on the epidemiology,transmission dynamics,vaccine,and non-pharmaceutical intervention evaluation of COVID-19,using interdisciplinary technologies,including Epidemiology,Infectious Disease,Statistics,Geographic Informatics and Ecology.These researches were conducted using clinical evaluation and both population-level and individual-level mechanistic transmission model techniques,which established reliable foundations for the understanding of COVID-19 and provided scientific evidence for the prevention and control of epidemic,the resumption of work and production,and the formulation of vaccine immunization strategies.
