A generalized SEIR epidemic model for transmission dynamics of SARS-CoV-2 and its dynamically consistent discrete model

MT Hoang

The aim of this work is to provide a new mathematical study for transmission dynamics of Coronavirus disease 2019 (COVID-19) that is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We first propose a generalized SEIR epidemic model using general nonlinear incidence rates that describe the” psychological” effect. Then, a rigorous mathematical analysis for the proposed model
is performed. We establish the positivity and boundedness, calculate the basic …
