Sweilam, N. H.; AL-Mekhlafi, S. M.; Almutairi, A.; Baleanu, D.

In this work, a novel mathematical model of Coronavirus (2019-nCov) with general population mask use with modified parameters. The proposed model consists of fourteen fractional-order nonlinear differential equations. Grünwald-Letnikov approximation is used to approximate the new hybrid fractional operator. Compact finite difference method of six order with a new hybrid fractional operator is developed to study the proposed model. Stability analysis of the used methods are given. Comparative studies with generalized fourth order Runge-Kutta method are given. It is found that, the proposed model can be described well the real data of daily confirmed cases in Egypt.
