The model’s formulation enhances the understanding of epidemic dynamics by considering disease transmission, recovery, and mortality rates under fractional calculus. Stability analyses are conducted for the disease-free equilibrium (DFE) and the pandemic fixed point (PFP), identifying critical conditions for finite-time stability using Lyapunov functions and fractional derivatives. Numerical simulations validate theoretical findings, demonstrating finitetime stabilization around the equilibrium points under realistic parameter settings. The results underscore the advantages of fractional-order modeling in capturing complex epidemic dynamics and highlight its potential to inform public health intervention strategies. 2025 266 282 3633 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.260123 https://www.americaspg.com/journal/21/article/3633 https://www.americaspg.com/storage/articles/manuscripts/01M3G7CFF95ATDZ55JR1A0WC88.pdf
