Fractional Analysis of Dynamical Novel COVID-19 by Semi-Analytical Technique

This study employs a semi-analytical approach, called Optimal Homotopy Asymptotic Method (OHAM), to analyze coronavirus (COVID-19) transmission model of fractional order. The proposed method Caputo's derivatives and Reimann-Liouville integral sense solve the underlying model. To best our knowledge, this work presents first application an optimal homotopy asymptotic scheme for better estimation future dynamics COVID-19 pandemic. Our fractional-order parameterized is based on available number infected cases from January 21 28, 2020, in Wuhan City China. For considered real-time data, basic reproduction R0 ≈ 2.48293 that quite high. solving possesses some salient features like producing closed-form solutions, fast convergence non-dependence discretization domain. Several graphical presentations have demonstrated dynamical behaviors subpopulations involved successful presented reveals new horizons its several other epidemiological models.
