报告摘要:Accurate prediction of epidemics is pivotal for making well-informed decisions for the control of infectious diseases, but modelling heterogeneity in the system becomes a challenge. In this talk, we propose a novel modelling framework integrating the spatio-temporal heterogeneity of susceptible individuals into homogeneous models, by introducing a continuous recruitment process for the susceptibles. Then, a general human heterogeneous disease model with mutation is proposed to comprehensively study the effects of human heterogeneity on basic reproduction number, final epidemic size and herd immunity. We show that human heterogeneity may increase or decrease herd immunity level, strongly depending on some convexity of the heterogeneity function.  Finally, we illustrate how to link the deep learning to dynamic model to examine time-dependent transmission rate or the intensity of interventions.
