Dynamics of an SEIR model with exogenous reinfections and quarantine control
|
Building upon the SEIR model proposed by Isaac Mwangi et al., our study analyzes the dynamic behavior of the SEIR model with exogenous reinfection influenced by quarantine control and transmission rates. In addition to the known backward bifurcation behavior, we prove that the model exhibits transcritical bifurcation when the basic reproduction number R0=1. Our results demonstrate the significant roles played by the disease transmission rate ß and the exogenous reinfection rate \tilde{p} (\tilde{p} is the exogenous reinfection rate influenced by quarantine) in altering the qualitative dynamics. We explore the global stability conditions of epidemic equilibrium under the joint influence of these two parameters. Furthermore, we investigate how our tuberculosis transmission model undergoes Hopf bifurcation under ß and \tilde{p}.
