We propose a mathematical model based on a set of delay differential equations that describe intracellular HIV CAL-MAG PLUS infection.The model includes three different subpopulations of cells and the HIV virus.The mathematical model is formulated in such a way that takes into account the time between viral entry into a target cell and the production of new virions.We study the local stability of the infection-free and endemic equilibrium states.Moreover, by using a suitable Lyapunov functional and the LaSalle invariant principle, it is proved that if the basic reproduction ratio is less than unity, the infection-free equilibrium is globally asymptotically stable.
In addition, we designed Hunting Gloves a non-standard difference scheme that preserves some relevant properties of the continuous mathematical model.
