Ebola virus disease (EVD) is one of the deadliest viral infections that has caused a serious
global health problem in the known human history. It was first transmitted to humans through …

Infectious diseases include all diseases caused by the transmission of a pathogenic agent
such as bacteria, viruses, parasites, prions, and fungi. They, therefore, cover a wide …

We derive a mathematical model that describes the competition of two populations in a
chemostat in the presence of a virus. We suppose that only one population is affected by the …

Compartmental epidemic models are intriguing in the sense that the generic model may
explain different kinds of infectious diseases with minor modifications. However, there may …

COVID-19 is an acute respiratory illness in humans caused by a coronavirus, capable of
producing severe symptoms and, in some cases, death, especially in older people and …

This paper analyses an SIRS epidemic model with the vaccination of susceptible individuals
and treatment of infectious ones. Both actions are governed by a designed control system …

In this paper, I propose a fractional-order mathematical five-dimensional dynamical system
modeling a SVEIR model of infectious disease transmission in a chemostat. A profound …

This paper focuses on the study and control of a non linear mathematical epidemic model
(SS vih VE LI) based on a system of ordinary differential equation modeling the spread of …

A SVEIR epidemic model with a delay in diagnosis is studied in a constant and variable
environment. The mathematical analysis shows that the dynamics of the model in the …

In this paper, an SEIR epidemic model with nonlinear incidence is considered. First, we
formulate the model and obtain its basic properties. Then, we find the equilibrium points of …
