Numerical simulation of a Coronavirus disease model with usingan efficient nonstandard nite difference scheme

In this manuscript, we introduce a new nonstandard nite difference (NSFD) scheme toapproximate solution of the coronavirus disease ۲۰۱۹ (COVID{۱۹) model. In the beginning,the positivity and boundedness of solution of the COVID{۱۹ model are discussed. Thestability analysis of the equilibrium points the proposed COVID{۱۹ model are then analyzed.Lastly, to ascertain the efficacy and accuracy of the suggested NSFD scheme, some numericalresults are provided.
