Global efficiency of local immunization on complex networks

Abstract: Epidemics occur in all shapes and forms: infections propagating in our sparse sexual networks, rumours and diseases spreading through our much denser social interactions, or viruses circulating on the Internet. With the advent of large databases and efficient analysis algorithms, these processes can be better predicted and controlled. In this study, we use different characteristics of network organization to identify the influential spreaders in 17 empirical networks of diverse nature using 2 epidemic models. … Show more

“…As clear from the exponential dependence on the k min and β , targeted vaccination strategy based on degree centrality provides a very efficient way to control epidemic spreading. Similar conclusions can be drawn by applying other centrality measures, such as betweenness and k-core centrality, or memberships, for the selection of immunized nodes [9,57,58,59,60,61].…”

“…At the same time immunization was also studied on meta-population networks [68]. In other studies, it has been argued that efficient immunization strategies can be developed by considering the higher-order organization of connectivity patterns [57,69,70,71,72,73,74]. Further studies proposed vaccination strategies using evolutionary games [75], or considering complex contagion processes [76].…”

“…A partir disso, foi encontrado que na propagação de epidemias os hubs eram mais propensos a ser infectados e, ademais, representavam os vértices com a maior capacidade de difusão da rede ou mais influentes (PASTOR-SATORRAS; VESPIGNANI, 2001;BARABáSI, 2002;KITSAK et al, 2010). Outros pesquisadores argumentam que os melhores propagadores são aqueles que apresentam maiores valores de betweenness (KITSAK et al, 2010;HéBERT-DUFRESNE et al, 2013). Esses indivíduos representam aqueles com uma posição estratégica na rede social, intermediando a comunicação entre grupos de vértices, aumentando assim sua influência.…”

“…Portanto, se esses vértices são vacinados, a difusão da epidemia perderia seu efeito, pois atuam como elos de ligação entre diferentes regiões da rede. Hébert-Dufresne et al (2013) fizeram uma análise local de várias medidas e encontraram que nas comunidades a medida de betweenness é um melhor descritor dos propagadores mais influentes.…”
