Background and objective For decades, mathematical models have been used to predict the
behavior of physical and biological systems, as well as to define strategies aiming at the …

In this article, we study a fractional order HIV/AIDS infection model with ABC-fractional
derivative. The model is based on four classes of a population. The study includes the …

The control of HIV demands different interventions for different age groups. In the present
manuscript, we formulate and analyze a mathematical compartmental models of HIV …

In this paper, we develop a mathematical model describing the dynamics of HIV
transmission by incorporating sexual orientation of individuals. Equilibrium points and the …

In this paper, we have considered a nonautonomous stage-structured HIV/AIDS epidemic
model having two stages of the period of infection according to the developing progress of …

We propose a mathematical model based on a set of delay differential equations that
describe intracellular HIV infection. The model includes three different subpopulations of …

The problem of the asymptotic dynamics of a quarantine/isolation model with time delay is
considered, subject to two incidence functions, namely standard incidence and the Holling …

An SEIR model with vaccination strategy that incorporates distinct incidence rates for the
exposed and the infected populations is studied. By means of Lyapunov function and …

Background Schistosomiasis japonica, caused by infection with Schistosoma japonicum, is
still recognized as a major public health problem in the Peoples' Republic of China …

In this paper, we apply the fractal-fractional derivative in the Atangana-Baleanu sense to a
model of the human immunodeficiency virus infection of CD4+ T-cells in the presence of a …
