Discrete Dynamics in Nature and Society, 2011, 1-21.doi:10.1155/2011/653937http://hdl.handle.net/10625/51660The bifurcation approach has been extensively utilized in theoretical epidemiology. The SEIS model takes into consideration the exposed or latent period of a disease; in the SEIS model an infection does not leave any immunity, thus individuals that have recovered return to being susceptible again. In this study bifurcations and dynamical behaviors of discrete SEIS models with exogenous reinfections are investigated along with some treatment strategies; results suggest treating a fixed percentage of exposed individuals.Text1 digital file (21 p. : ill.)Application/pdfenCOMPLEX DYNAMICSDISCRETE SEIS MODELSSIMPLE DEMOGRAPHYMATHEMATICAL MODELSEPIDEMIOLOGYJournal Article (peer-reviewed)
