The system of ODE’s involving Sickle Cell, HIV and T-Cells are formulated with the aid of biological mathematical model. The eigen values are obtained to test for the trivial steady state solution or points using characteristic equation which is analytical. Finally, numerical simulations were carried out to test the level of reliability of the result.
