In this project, we consider a system of five ordinary differential equations which describe the population dynamics of HIV/AIDS when individuals are tested for the virus and then moved onto antiretroviral therapy. We include a Holling Type-II response to model the complacency of the population in response to the number of AIDS cases. We prove global stability of the disease-free equilibrium when the basic reproductive ratio is less than one. We then derive an optimal control problem and solve it theoretically using Pontryagin's Maximum Principle and numerically using the Forward-Backward Sweep Method. We conclude with a discussion on the impact of optimal educational strategies to combat complacency regarding the AIDS/HIV epidemic.
