We investigate the spread of diseases, computer viruses or information on complex
networks and also immunization strategies to prevent or control the spread. When an entire
population cannot be immunized and the effect of immunization is not perfect, we need the
targeted immunization with immunization rate. Under such a circumstance we calculate
epidemic thresholds for the SIR and SIS epidemic models. It is shown that, in scale-free
networks, the targeted immunization is effective only if the immunization rate is equal to one …
We investigate the spread of diseases, computer viruses or information on complex networks and also immunization strategies to prevent or control the spread. When an entire population cannot be immunized and the effect of immunization is not perfect, we need the targeted immunization with immunization rate. Under such a circumstance we calculate epidemic thresholds for the SIR and SIS epidemic models. It is shown that, in scale-free networks, the targeted immunization is effective only if the immunization rate is equal to one. We analyze here epidemic spreading on directed complex networks, but similar results are also valid for undirected ones.
