Study of global dynamics of COVID-19 via a new mathematical model

Abstract

The theme of this paper focuses on the mathematical modeling and transmission mechanism of the new Coronavirus shortly noted as (COVID-19), endangering the lives of people and causing a great menace to the world recently. We used a new type epidemic model composed on four compartments that is susceptible, exposed, infected and recovered (SEIR), which describes the dynamics of COVID-19 under convex incidence rate. We simulate the results by using nonstandard finite difference method (NSFDS) which is a powerful numerical tool. We describe the new model on some random data and then by the available data of a particular regions of Subcontinents.

A mathematical system of COVID-19 disease model: Existence, uniqueness, numerical and sensitivity analysis

“…In [ 11 ], Giordano et al proposed a model that predicted the course of the epidemic to reach an efficient controlling strategy. Din et al used an epidemic model for describing the dynamic of COVID-19 under convex incidence rate [ 12 ]. A fractional-order model for COVID-19 transmission was presented in [ 13 ] and its approximated solutions were obtained using the homotopy-Laplace transform method.…”

Hybridizing intra and extra perspectives in infectious disease modeling

“…A SEIRD (Susceptible-Exposed-Infected-Recovered-Deceased) with three forms of infection (benign, respiratory, and severe forms) is presented in [4]. Other mathematical models to control the spread of infectious diseases are studied in [5][6][7][8][9][10][11][12][13][14][15].…”

Optimization of Site Selection for Emergency Medical Facilities considering the SEIR Model

“…Numerical simulations revealed that the parameters in the model were accurately identified [ 12 ]. Din et al [ 13 ] studied the mathematical model and transmission mechanism of COVID-19 and used a new type of epidemic model composed of four compartments: SEIR to describe the dynamics of COVID-19 under a convex incidence rate [ 13 ]. Zhang et al [ 14 ] comprehensively considered the transmission characteristics of COVID-19, the impact of prevention and control interventions, medical conditions, the impact of medical resource availability, and other factors.…”
