"Study of global dynamics of COVID-19 via a new mathematical model", Results in Physics, Vol. 19.2211-3797http://hdl.handle.net/20.500.12416/6071The theme of this paper focuses on the mathematical modeling and transmission mechanism of the new Coronavirus shortly noted as (COVID-19), endangering the lives of people and causing a great menace to the world recently. We used a new type epidemic model composed on four compartments that is susceptible, exposed, infected and recovered (SEIR), which describes the dynamics of COVID-19 under convex incidence rate. We simulate the results by using nonstandard finite difference method (NSFDS) which is a powerful numerical tool. We describe the new model on some random data and then by the available data of a particular regions of Subcontinents.eninfo:eu-repo/semantics/openAccessBasic Reproduction NumberConvex Incidence RateCOVID-19Disease-Free EquilibriumMathematical ModelingStabilityArticle1910.1016/j.rinp.2020.103468
