In this paper, a mathematical model of the COVID-19 pandemic with lockdown that provides
a more accurate representation of the infection rate has been analyzed. In this model, the …

In this paper, a compartmental model on the co-infection of pneumonia and HIV/AIDS with
optimal control strategies was formulated using the system of ordinary differential equations …

An HIV/AIDS epidemic model with different latent stages and treatment is constructed. The
model allows for the latent individuals to have the slow and fast latent compartments …

This technical note studies impulsive stabilization of general nonlinear systems with time-
delay. Distributed time-delay is considered in the proposed nonlinear impulsive controller …

Human immunodeficiency virus (HIV) is a viral infection that infects CD4+ lymphocyte cells,
and as a result, the body's immune system is destroyed and unable to fight against the …

On the basis of the SIQR epidemic model, we consider the impact of treatment time on the
epidemic situation, and we present a differential equation model with time-delay according …

Impulsive systems have attracted an increased interest of numerous researchers around the
globe due to their important applications in many areas. Some typical physical systems …

Epidemic outbreak is one of the primary issue that induce behavioural changes in healthy
individuals to avoid contracting infection. We here propose a compartmental model for the …

In this paper, we have developed a compartment of epidemic model with vaccination. We
have divided the total population into five classes, namely susceptible, exposed, infective …

Background Viral diseases are highly widespread infections caused by viruses. These
viruses are passing from one human to other humans through a certain medium. The …
