A simple nonlinear SIR mathematical model describing the use of gonorrhea public enlightenment as a control in the presence of treatment of gonorrhea infectives is considered to assess the contribution of behavioural change among the enlightened gonorrhea susceptible individuals. The enlightenment programme resulted in a change in the behaviour of enlightened gonorrhea susceptible individuals thereby splitting the susceptible class into three. The basic properties of the model are considered and the basic reproduction number (R0) was determined. It was shown that, a decrease in the rate at which susceptible individuals know their gonorrhea status (P), increases the value of the basic reproduction number (R0), the population of unaware susceptible individuals (S) and aware susceptible individuals (S1). On the contrary, a decrease in decreases the population of enlightened gonorrhea susceptible individuals who remain faithful to their uninfected sexual partners for life (S2) as well as infected (I) and recovered (R) individuals. Also, a decrease in the incidence rate of unaware neisseria gonorrhea susceptible individuals per unit time (B1) decreases the basic reproduction number (R0) and the populations of infected (I) and recovered (R) individuals, while the susceptible populations (S, S1, and S2) increase slightly. Finally, decreasing the incidence rate of aware neisseria gonorrhea susceptible individuals per unit time (B2) gradually decreases the basic reproduction number (R0) and, the populations of infected (I) and recovered (R) individuals, while the susceptible populations (S, S1, and S2) increase slightly. It is therefore recommended that, the relevant agencies should increase the rate of public enlightenment so as to bring the population of susceptible individuals to the barest minimum.
