GEOGRAPHICAL SEVIRD COVID-19 MODEL WITH TRAVEL RESTRICTIONS

Susceptible-Infected-Recovered (SIR) models have been widely used to study the spread of Covid-19. These models have been improved to include other states (e.g., exposed, deceased) as well as geographical level transmission dynamics. In this paper, we present an extension to an existing SEVIRD (Susceptible - Exposed - Vaccinated - Infected - Recovered - Death) model to include the effect of air and maritime travel as well as travel restrictions. We use the model to simulate the spread of Covid-19 through 13 different countries. The case study shown illustrates how the model can be used for rapid prototyping at a geographical level and adapted to include changing policies. © 2022 Society for Modeling & Simulation International (SCS)

Spatial Models and Masks in Indoor Analysis for the Spread of COVID-19

Face masks have been shown to slow or stop the spread of airborne COVID-19 droplets and aerosols. There is an apparent lack of research examining the effect of different types of masks used at the same time, and their impact on the spread of viral particles in a spatial sense. We introduce a rapid prototype model to overcome the issues in the available research using the Cell-DEVS formalism. We also build scenarios for the model to examine the effectiveness of all types of masks and respirators recommended by the World Health Organization on the spread of viral particles in an indoor environment. © 2021 IEEE.
