Numerical Solution of non-linear mathematical model of TB/HIV Co-infection

Abstract

To get a better understanding of HIV/TB co-infection, we've constructed and tested a mathematical model. This model includes a set of first order non-linear Ordinary Differential Equations with six exclusive compartments; for example, people infected with TB (TB-infected), HIV (HIV-infected), or people infected with both (co-infected) (A). Compartment transitions have been shown. It's worth pointing out that the paper mentions the existence of a positive invariant area and positive solution. The researchers were able to support their conclusions by employing MATLAB and in-depth computer simulations.
