Analysis and Dynamics of Fractional Order Mathematical Model of COVID-19 in Nigeria Using Atangana-Baleanu Operator

We propose a mathematical model of the coronavirus disease 2019 (COVID-19) to investigate transmission and control mechanism in community Nigeria. Using stability theory differential equations, qualitative behavior is studied. The pandemic indicator represented by basic reproductive number R0 obtained from largest eigenvalue next-generation matrix. Local as well global asymptotic conditions for disease-free equilibrium are which determines stabilize exponential spread disease. Further, we examined this using Atangana–Baleanu fractional derivative operator existence criteria solution established. consider data reported infection cases April 1, 2020, till 30, parameterized model. have used one reliable efficient method known iterative Laplace transform obtain numerical simulations. impacts various biological parameters on dynamics COVID-19 examined. These results based different values parameter serve identify significant strategies In end, demonstrated graphically justify our theoretical findings.
