报告摘要：We developed several differential equations models of COVID-19 epidemics that use early reported case data from around the world to predict the future number of cases. These models incorporate three important elements of COVID-19: (1) the number of asymptomatic infectious individuals (with very mild or no symptoms), (2) the number of symptomatic reported infectious individuals (with severe symptoms), and (3) the number of symptomatic unreported infectious individuals (with less severe symptoms). From the parameterized model we identify the number of unreported cases. We then use the model to project the epidemic forward with varying level of public health interventions. This is a joint work with Pierre Magal (University of Bordeaux, France), Ousmane Seydi (Ecole Polethnique de Thies, Senegal) and Glenn Webb (Vanderbilt University, USA).
