Towards a Realistic Model for Simulating Spread of Infectious COVID-19 Disease

ABSTRACT

The classical compartment model namely SEIR was not designed originally for COVID-19. There are significant numbers of people infected by COVID-19 did not get sick immediately but have become carriers of COVID-19. The patients might have certain length of incubation period. In order to cover the quarantine and asymptomatic variables, the existing SEIR model is extended to a multi-compartment infectious disease model. The contribution presented in this paper is a new model called SEAIRD which caters for the new characteristics of the 2019-nCoV, therefore applicable for the inclusion of asymptomatic population in the simulation. © 2020 ACM.
