The Impact of Intervention Strategies on the Dissemination of Monkeypox Utilizing Fractional Differential Equations

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this study, we develop a compartmental mathematical model to offer a thorough understanding of the dynamics of monkeypox viral transmission. We examine the sensitivity of the epidemic model to the fundamental reproduction number (R0). We also utilize an expanded Euler technique to scrutinize the dynamics of monkeypox transmission between humans and ...
