Mathematical analysis of COVID-19 disease in Malaysia using SIRS model

Abstract

This research analyses a prior mathematical framework that represents the COVID-19 disease epidemiology in Malaysia. The relevant three compartments that constitute the framework, such as Susceptible, Infected, as well as Recovered, are solved semi-analytically using Homotopy analysis technique and Laplace Adomian decomposition approach. The approximate analytical expressions for all of the three different compartments are provided. To show their effects, a variety of model parameter types are visually depicted. Tables are provided to demonstrate the effects of the parameters on the outcomes. With this strategy, the error approximation attains relatively small values. A satisfactory fit between the numerical simulation (MATLAB) and the approximate analytical results is obtained.
