Abstract
This study develops and analyzes mathematical models to understand and evaluate prevention measures for HIV (Human Immunodeficiency Virus) and AIDS (Acquired Immunodeficiency Syndrome) in Kenya, with particular focus on high-risk populations. The research employs a deterministic compartmental model using Ordinary Differential Equations (ODEs) to simulate disease transmission dynamics. The population is divided into three compartments: Susceptible (S), HIV-infected without AIDS symptoms (I), and AIDS patients (A). The model's analysis includes derivation of the basic reproduction number (R?), investigation of equilibrium points, and stability analysis. Mathematical analysis demonstrates the existence of both disease-free and endemic equilibrium points. The model is locally asymptotically stable when R? < 1, indicating effective disease control. Key findings reveal that Pre-Exposure Prophylaxis (PrEP) emerges as the most effective single intervention, potentially reducing HIV incidence significantly among Men who have Sex with Men (MSM) in Kenya. Early diagnosis shows substantial impact, while early Anti-Retroviral Therapy (ART) demonstrates limited effectiveness when implemented alone. The combined implementation of all three interventions (PrEP, early diagnosis, and early treatment) yields optimal results in HIV prevention. The study provides quantitative evidence to support policy decisions regarding HIV prevention strategies in Kenya, particularly emphasizing the importance of PrEP programs and early diagnosis initiatives. These findings have significant implications for resource allocation and public health policy in HIV/AIDS prevention programs.
