Deterministic model reveals stable disease-free equilibrium in rabies transmission dynamics, suggesting effective intervention strategies including vaccination and health promotion.
This study presents a deterministic model to investigate rabies transmission dynamics, incorporating environmental effects and control strategies using optimal control theory. Qualitative and quantitative analyses reveal that the disease‐free equilibrium is stable when the effective reproduction number and unstable when . Mesh and contour plots illustrate an inverse relationship between and control strategies, including dog vaccination, health promotion, and postexposure treatment. Increased intervention reduces transmission, while higher contact rates among dogs raise . Numerical simulations with optimal control confirm the effectiveness of integrated strategies. Vaccination and treatment are identified as key interventions for achieving rabies elimination within 5 years.
