RESUMO

We have developed a deterministic mathematical model based on the mass-action principle, in analogy to the works that study the dynamics of infectious diseases in Epidemiology. We analyzed the dynamic of rumors spreading, taking into account the symmetry of contacts among susceptible and infectious individuals and studied the implications of an educative broadcasting advertising in the model. Afterwards, we proposed a simplification ot the model excluding the contact among susceptible and infected individuals supposedly more resistant to novelities. Their implications to the spread of rumor and its connection with parameters describing social behavior are discussed.
