Title: Modelling the deceleration of COVID-19 spreading

Speaker: Marco Baiesi

Abstract: An analysis of COVID-19 data detects a deceleration of the epidemic in its early stages, often before a lockdown. Moreover, from the deceleration of the number of new cases we can also quantify the portion of population not involved in the lockdown, in different countries. Our analysis starts by characterising the time evolution of COVID-19 in term of its "velocity" (log of the new cases per day) and its rate of variation, or "acceleration" and continues by modifying a susceptible-hidden-infected-recovered (SHIR) model introduced in 2020 by Barnes. A partial hiding mechanism, for instance due to the impossibility for a fraction of the population to enter the hidden state, yields a simple model that can reproduce different deceleration trends. We also discuss other related simple models of COVID-19.
