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