Abstract :
In this paper, a SIRS epidemic model with immunization on sparsely distributed regular lattice is proposed. Based on the model, we research the effects of immunized rate, crowd-density, spread efficiency and moving activity of agents on disease spread. The theoretical analysis and analog simulation indicate that immunization can increase the spreading threshold. Besides, there is a critical threshold which is related to spread efficiency and crowd-density in this model. Only the product of spread efficiency and crowd density is beyond the threshold, can the disease spread in crowd continuously and steadily. Our research also shows that moving activity of agents can promote the disease spread.
