    (contaminated foods-to-human) transmission routes via the Caputo fractional and fractional-fractal modeling approaches. +e model is vigorously analyzed both theoretically and numerically. +e possible equilibrium points of the system and their existence are investigated based on the reproduction number. +e model exhibits three equilibrium points, namely, infection-free, infected 6ying foxes free, and endemic. Furthermore, novel numerical schemes are derived for the models in fractional and fractalfractional cases. Finally, an extensive simulation is conducted to validate the theoretical results and provide an impact of the model on the disease incidence. We believe that this study will help to incorporate such mathematical techniques to examine the complex dynamics and control the spread of such infectious diseases.
