چکیده

Abstract The purpose of this article is to formulate a simplified nonlinear fractional mathematical model illustrate the dynamics new coronavirus (COVID-19). Based on infectious characteristics COVID-19, population divided into five compartments: susceptible S ( t ), asymptomatic infection I unreported symptomatic U reported infections W T ) and recovered R collectively referred as (SIUWR). existence, uniqueness, boundedness, non-negativeness proposed solution are established. In addition, basic reproduction number 0 calculated. All possible equilibrium points examined their local global stability under specific conditions discussed. disease-free point locally asymptotically stable for leq 1 unstable > 1. endemic with respect Perform numerical simulations using Adams–Bashforth–Moulton-type predictor–corrector PECE method validate analysis results understand effect parameter variation spread COVID-19. For simulations, behavior approximate displayed in form graphs various orders. Finally, brief conclusion about simulation how transmission social work.

Modeling and analysis of the spread of the COVID-19 pandemic using the classical SIR model

In this paper modeling, analysis and prediction of novel epidemic of COVID-19 are concerned to identify effective spread parameters of it in Iran. For this purpose, the basic susceptible-infected-removed (SIR) model is used which has two parameters: the infection rate and remove rate. The occurrence of several maximum points in the Iranian data and the single peak of the SIR model makes it impo...

The Pandemic Paradox: Concurrence of Covid-19 and Metabolic Syndrome

The health-care system should be ready to deal with a large number of COVID-19 patients who may require critical care. Patients with severe consequences should have well-rehearsed and structured protocols for quick identification, isolation, triage, and care plans. The higher incidence of metabolic syndrome combined with COVID-19 shows that concurrence of these two disorders, as well as the the...

Stability Analysis of a Fractional Order Model of HIV virus and AIDS Infection in the Community

In  this  paper a  non-linear  model  with  fractional  order  is  presented  for  analyzing  and  controlling the  spread  of  HIV virus.  Both  the  disease-free  equilibrium and the endemic equilibrium are  found  and  their  stability is  discussed. The basic reproduction number , which is a function of the constant parameters in the model, plays an essential  role in the stability of  the ...
