  A model for the transmission dynamics of gonorrhoea with control
incorporating passive immunity is formulated. We show that introduction of
treatment or control parameters leads to transcritical bifurcation. The
backward bifurcation coefficients were calculated and their numerical
perturbation results to different forms of equilibria. The calculated effective
reproduction number of the model with control is sufficiently small. This
implies asymptotically stability of the solution, thus, the disease can be
controlled in a limited time.
