In this study, we proposed the dynamics model of Conjunctivitis with taken into account the education campaign. We analyzed the model by standard method which we determined equilibrium points and investigated the stability of the model. The basic reproductive number is obtained through the next generation method. The basic reproductive number is
In epidemiology, the basic reproductive number is the number of secondary case generate by a primary infectious case (van den Driesch and Watmough,2002).For mathematician, the basic reproductive number is the threshold parameter for determining the stability of the model at each equilibrium points. The stability of the system is investigated using the Roth-Hurwitz criteria. The qualitative behaviors of this model are shown as Fig. 2 and 3. We can see that when the value of effectiveness of education campaign increase, the the basic reproductive number is less than one, meaning that the Conjunctivitis die out from the community. On the other hand, when the value of effectiveness of the education campaign decrease. The basic reproductive number is greater than one, meaning that the Conjunctivitis occur in the community. We found that if p = 0.005 , R0 is 0.0996 and when p = 0.005 , R0 is 1.099
