摘要：

In this work, we present a mathematical framework that captures the dynamic behavior of the simultaneous propagation of two strains of COVID-19. We apply the next-generation matrix method to compute the basic reproduction ratio R-0. We investigate the stability of the model at each of the feasible equilibria. To validate our theoretical results, we have conducted numerical simulations. It is observed that if R-0 <= 1, eventually there will be no disease. However, if R-0 > 1, a competition between the two COVID-19 strains will occur, and the more infectious variant will survive while the other disappears.
