The mathematical
models of infections are essential tools in understanding the dynamical
behavior of disease transmission. In this paper, we establish a model of
differential equations with piecewise constant arguments that explores the
outbreak of Covid-19 including the control mechanisms such as health
organizations and police supplements for the sake of controlling the pandemic
spread and protecting the susceptible population. The local asymptotic
stability of the equilibrium points, the disease-free equilibrium point, the apocalypse
equilibrium point and the co-existing equilibrium point are analyzed by
the aide of Schur-Cohn criteria.
Furthermore and
by incorporating the Allee function at time t, we consider the
extinction case of the outbreak to analyze the conditions for a strong
Allee Effect. Our
study has demonstarted that the awareness of the police personal and the
management of professional health organizations play a vital role to protect
the susceptible class and to prevent the spreading. Numerical simulations are
presented to support our theoretical findings. We end the paper by a
describtive conclusion.
