  We formulate and analyse a robust mathematical model of the dynamics of
gonorrhoea incorporating passive immunity and control. Our results show that
the disease-free and endemic equilibria of the model are both locally and
globally asymptotically stable. A sensitivity analysis of the model shows that
the dynamics of the model is variable and dependent on waning rate, control
parameters and interaction of the latent and infected classes. In particular,
the lower the waning rate, the more the exponential decrease in the passive
immunity but the susceptible population increases to the equilibrium and wanes
asymptotically due to the presence of the control parameters and restricted
interaction of the latent and infected classes.
