Analysis of fractional susceptible-exposed-infectious (SEI) model of COVID-19 pandemic for India

Abstract

The purpose of this article is to develop and analyse COVID-19 pandemic for India in terms of mathematical equations. We consider the basic Susceptible-Exposed-Infectious (SEI) epidemic model and develop the SEI model of COVID-19 for India. We use Adomian decomposition method to find solution of the group of fractional differential equations. We discuss the stability by using Routh-Hurwitz criterion for disease-free equilibria point and endemic equilibrium point. We obtain approximate solution of the group of fractional differential equations and its solution represented graphically by Mathematica software, that will be helpful to mininize the infection.
