A study of fractional-order monkeypox mathematical model with its stability analysis

In more recent times, many monkeypox disease cases have steadily increased and the range of the projected outbreaks in human populations has grown constantly. In the light of these aspects, this work proposes a new fractional-order version for one of the Susceptible-Exposed-Infectious-Recovered models (or simply SEIR models). This model, which is formulated in the sense of Caputo fractional differentiator, is first analyzed in terms of finding some theoretical results related to the stability analysis and the basic reproduction number. Then, with the help of using a novel recent version of the fractional Euler method, called Fractional Modified Euler Method (FMEM), the proposed model is solved numerically. Several numerical simulations are presented afterward for completeness.
