We study the combined effects of aging and links removal on epidemic dynamicsin the Barab\'{a}si-Albert scale-free networks. The epidemic is described by asusceptible-infected-refractory (SIR) model. The aging effect of a nodeintroduced at time $t_{i}$ is described by an aging factor of the form$(t-t_{i})^{-\beta}$ in the probability of being connected to newly added nodesin a growing network under the preferential attachment scheme based onpopularity of the existing nodes. SIR dynamics is studied in networks with afraction $1-p$ of the links removed. Extensive numerical simulations revealthat there exists a threshold $p_{c}$ such that for $p \geq p_{c}$, epidemicbreaks out in the network. For $p < p_{c}$, only a local spread results. Thedependence of $p_{c}$ on $\beta$ is studied in detail. The function$p_{c}(\beta)$ separates the space formed by $\beta$ and $p$ into regionscorresponding to local and global spreads, respectively.Comment: 8 pages, 3 figures, revtex, corrected Ref.[11
