Abstract
In this paper, we developed and analyzed a non-linear mathematical model for the effect of awareness programs driven by the media on the spread of Leptospirosis. The awareness program are treated as an intervention for the emergent disease. We divided the susceptible populations into two sub-classes: susceptible class and aware susceptible class. We assumed that susceptible individuals who come across with media campaign move to aware susceptible class and in general avoid contact with infection. This model is analyzed by using stability theory of differential equations. The results show that if the basic reproduction number R0 < 1, then the disease dies out, however, if R0 < 1 , then the disease becomes endemic. Our analysis shows that the awareness programs driven by the media have positive impact in reducing the infection prevalence of the infective population
