(a) Bifurcation diagram of system (2). The epidemiological importance of the existence of bifurcation especially a backward bifurcation in meningitis transmission model depicts that the classical requirement of having the basic reproduction number , although necessary, is not sufficient for controlling the meningitis disease. (a) Backward bifurcation occurs in system (2) for and , and (b) forward bifurcation will be achieved for and .
