We consider the long-term properties of a stochastic SVIR epidemic model with saturation
incidence rates and logistic growth in this paper. We firstly derive the fitness of a unique …

In this paper, we construct a stochastic SAIR (Susceptible–Asymptomatic–Infected–
Removed) epidemic model to study the dynamic and control strategy of COVID-19. The …

COVID-19 is a highly infectious disease, and in very recent times, it has shown a massive
impact throughout the globe. Several countries faced the COVID-19 infection waves multiple …

Due to its complex nature, Coronavirus has perplexed many researchers worldwide and
endangered the lives of people across the globe forcing them to take social distancing and …

We consider an SAIRS epidemic model with vaccinations and treatment, where
asymptomatic and symptomatic infectious individuals are considered in the transmission of …

This article introduces a broad formulation of fractional optimal control issues characterized
by a class of Caputo fractional systems within Hilbert spaces. Through a variational method …

A mathematical model has been proposed to consider two distinct forms of psychological
pressure that arise due to the COVID-19 situation and their impact on individuals' lives …

The stochastic Ebola epidemic model with a combination of nonlinear incidence functions is
analyzed to gain deeper insights into the complex dynamics of disease transmission. We …

In this article, the qualitative properties of a stochastic dual virus parallel transmission model
with immunity delay are analyzed. First, we use Lyapunov theory to study the existence and …

The present study aims to investigate the dynamic behavior of a stochastic SIRI model with
logistic birth and saturated incidence rate. First, we show that the solution of the proposed …
