Dynamical Analysis of a Mathematical Model of COVID-19 Spreading on Networks

Frontiers in Physics, 2021
In this article, an SEAIRS model of COVID-19 epidemic on networks is established and analyzed. Following the method of the next-generation matrix, we derive the basic reproduction number R0, and it shows that the asymptomatic infector plays an important ...
