The paper aims to investigate an HIV epidemic fractional model. The fractional derivatives
are described in the sense of Caputo operator and Constant Proportional Caputo (CPC) …

The goal of this paper is to study the threshold dynamics of an HIV-1 viral infection model
with cell-mediated immune responses and direct cell-to-cell transmission mechanism. The …

Human immunodeficiency virus (HIV) and human T-lymphotropic virus type I (HTLV-I) are
two retroviruses that attack the immune cells and impair their functions. Both HIV and HTLV-I …

This paper proposes and analyzes a CTL-mediated HIV infection model. The model
describes the interaction between healthy CD4+ T cells, silent infected cells, active infected …

In this paper, we formulate the intricate process of Human Immunodeficiency Virus (HIV)
infection in a mathematical model. In the formulation of the model, the density of CD 4+ T …

This paper constructs approximate solutions of the epidemic system of HIV/AIDS
transmission model with the help of the conformable fractional differential transform method …

A mathematical model is proposed for the dynamics of HIV/AIDS with incorporation of weak
CD4+ T cells. The model considers three different categories of cells: uninfected CD4+ T …

In this paper, a mathematical model is formulated to investigate the effect of cytotoxic T
lymphocyte (CTL) immune response on human immunodeficiency virus (HIV) infection …

Human immunodeficiency virus type 1 (HIV-1) and human T-lymphotropic virus type I (HTLV-
I) are two retroviruses which infect the same target, CD 4+ T cells. This type of cell is …

In the literature, a great number of HIV and HTLV-I mono-infection models has been
formulated and analyzed. However, the within-host dynamics of HIV/HTLV-I co-infection has …
