How safe is re-opening? Real time modelling and resurgence risk in COVID-19

Abstract: As re-opening begins, it is essential to understand the risk that it brings. We have developed a model of COVID-19 based on the well-known SEIR framework, but accounting for social distancing among a portion of the population that is able and willing to participate. We use a Bayesian approach to fit the model to data from several Canadian provinces, and other jurisdictions. In this talk I will discuss the idea of current and re-opening risk, with reference to the probability that a jurisdiction is at or near the critical threshold, the likely impacts of increase the contact rate in the general population by a fixed percent, and the case burden that this is expected to cause. I will comment on how we might frame the risk of re-opening borders between jurisdictions. Finally, I will comment on the data needs of modelling and on key unknowns that remain.
