In this study, we classify the genera of COVID-19 and provide brief
information about the root of the spread and the transmission from animal (natural
host) to humans. We establish a model of fractional-order differential equations to
discuss the spread of the infection from the natural host to the intermediate one,
and from the intermediate one to the human host. At the same time, we focus on
the potential spillover of bat-borne coronaviruses. We consider the local stability
of the co-existing critical point of the model by using the Routh–Hurwitz Criteria.
Moreover, we analyze the existence and uniqueness of the constructed initial
value problem. We focus on the control parameters to decrease the outbreak from
pandemic form to the epidemic by using both strong and weak Allee Effect at
time t. Furthermore, the discretization process shows that the system undergoes
Neimark–Sacker Bifurcation under specific conditions. Finally, we conduct a series of numerical simulations to enhance the theoretical findings.
