Figure 2

Illustration of the variations of the final infected density and the epidemic threshold with respect to the parameters α and δ . Left: Plot of ρ versus α and δ. When considering ρ versus α, we set \(\delta= 0.5\); when considering ρ versus δ, we set \(\alpha= 0.4\). Right: The variation of the infection threshold \(\lambda_{c}\) with respect to δ over BA scale-free network for different \(\tau=\frac{\delta}{\alpha+\delta}\). Other parameters are chosen as \(\gamma_{1}=\gamma_{2}=0.6\), \(\beta=0.8\) and \(\langle k\rangle=10\).
