The aim of this work is to provide a new mathematical model that studies transmission
dynamics of Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2). The model captures the dynamics of the disease taking into
consideration some measures and is represented by a system of nonlinear ordinary differential
equations including seven classes, which are susceptible class (S), exposed class (E), asymptomatic
infected class (A), severely infected class (V), hospitalized class (H), hospitalized class but in ICU
(C) and recovered class (R). We prove positivity and boundedness of solutions, compute the basic
reproduction number, and investigate asymptotic stability properties of the proposed model.
