Complex networks such as the sexual partnership web or the Internet often show a high degree of redundancy and heterogeneity in their connectivity properties. This peculiar connectivity provides an ideal environment for the spreading of infective agents. Here we show that the random uniform immunization of individuals does not lead to the eradication of infections in all complex networks. Namely, networks with scale-free properties do not acquire global immunity from major epidemic outbreaks…

Global efficiency of local immunization on complex networks

This study uses different characteristics of network organization to identify the influential spreaders in 17 empirical networks of diverse nature using 2 epidemic models and develops an analytical framework that highlights a transition in the characteristic scale of different epidemic regimes.

Reactive immunization on complex networks

This work proposes a novel vaccination scheme that exploits information from the details of the infection pattern at the moment when the vaccination strategy is applied and shows that the proposed immunization strategy is effective and robust on a wide class of complex networks.

A novel immunization strategy is proposed which aims at immunizing the nodes with highest betweenness and can reduce the epidemic propagation velocity especially in the higher modularity networks.

Non massive immunization to contain spreading on complex networks

It is reported that moderate and weakly supervised immunizations can lead to finite epidemic thresholds of the susceptible-infected-susceptible model on scale-free networks by changing the nature of the transition from a specific motif to a collectively driven process.

Behaviors of susceptible-infected epidemics on scale-free networks with identical infectivity.

A susceptible-infected model with identical infectivity, in which, at every time step, each node can only contact a constant number of neighbors is proposed, which indicates the existence of an essential relationship between network traffic and network epidemic on scale-free networks.

Immunization of networks with limited knowledge and temporary immunity.

A theoretical framework for studying targeted immunization in networks, where only n nodes can be observed at a time with the most connected one among them being immunized and the immunity it has acquired may be lost subject to a decay probability ρ.

An Efficient Control Strategy of Epidemic Spreading on Scale-Free Networks

This work presents a novel and effective method for controlling epidemic spreading on complex networks, especially on scale-free networks, which is more effective in realizing the control of epidemic spreading in complex networks and can better retain the integrity of complex networks.

Epidemic spreading with immunization rate on complex networks

It is shown that, in scale-free networks, the targeted immunization is effective only if the immunization rate is equal to one, and similar results are also valid for undirected ones.
