This paper delves into the investigation of the COVID-19 dynamics within a host using the
Target-Latent-Infected-Virus (TLIV) model, presenting a fresh approach compared to …

The COVID-19 pandemic has highlighted the profound impact of the SARS-CoV-2 virus as a
significant threat to human health. There is an urgent need to develop a comprehensive …

In recent years, the stability of the predator–prey model subject to the Allee effect has
become an interesting issue. This study investigates the effect of Allee effect on the stability …

The present study discussed a model to describe the SARS-CoV-2 viral kinetics in the
presence of saturated antiviral responses. A discrete-time delay was introduced due to the …

Abstract National Survey on Drug Use and Health indicates that Alcohol, Tobacco, and
Marijuana are the most commonly abused drugs in the US. Poly-substance use of these …

In this paper, we analyze the stochastic SIV model for COVID-19 at the within-host level and
explore its dynamics. We first examine the existence and positivity of the solution of the …

In the present work we introduced and analyzed the most basic transmission SEI
(susceptible-exposed-infective) model for a directly transmitted infectious disease caused by …

In this paper, an epidemic SI model with n-infectious stages is studied. Lyapunov functions
are used to conduct the global stability analysis for equilibrium points. The n-basic …

In this paper, a stochastic SIS epidemic infectious diseases model with double stochastic
perturbations is proposed. First, the existence and uniqueness of the positive global solution …
