摘      要：In this work,the spread of a contagious disease on a society where the individuals may take precautions is *** primary assumption is that the infected individuals transmit the infection to the susceptible members of the community through direct contact *** the meantime,the susceptibles gather information from the adjacent sites which may lead to taking *** SIR model is used for the diffusion of infection while the Bass equation models the information *** sociological classification of the individuals indicates that a small percentage of the population takes action immediately after being informed,while the majority expects to see some real advantage of taking *** individuals are assumed to take two different *** precursory measures are getting vaccinated or trying to avoid direct contact with the neighbors.A weighted average of states of the neighbors leads to the choice of *** fully connected and scale-free Networks are employed as the underlying network of *** comparison between the simple contagion diffusion and the diffusion of infection in a responsive society showed that a very limited precaution makes a considerable difference in the speed and the size of the spread of ***,highly connected hub nodes play an essential role in the reduction of the spread of disease.
