Analysis of a Tuberculosis Infection Model considering the Influence of Saturated Recovery (Treatment)

Figure 8

(a) Forward bifurcation and (b) backward bifurcation of endemic equilibria where the infected individuals are plotted as a function of . The blue dash line represents the stable equilibrium while the red dash line represents the unstable equilibrium. (a) shows forward bifurcation at the critical value , and the parameter values used include , , , , , , , and , while (b) represents backward bifurcation and parameters used are the same as in (a) except .
