Impact of media coverage on epidemic spreading in complex networks

Abstract

h i g h l i g h t s• A new SIS network model obtained by introducing an information variable is proposed. • The diseases can be controlled through high efficiency of implementation.• The introduced parameters have significant impact on the final prevalence density.• The results may suggest effective control strategies incorporating media coverage. a b s t r a c t An SIS network model incorporating the influence of media coverage on transmission rate is formulated and analyzed. We calculate the basic reproduction number R 0 by utilizing the local stability of the disease-free equilibrium. Our results show that the disease-free equilibrium is globally asymptotically stable and that the disease dies out if R 0 is below 1; otherwise, the disease will persist and converge to a unique positive stationary state. This result may suggest effective control strategies to prevent disease through media coverage and education activities in finite-size scale-free networks. Numerical simulations are also performed to illustrate our results and to give more insights into the dynamical process.

Dynamic Rankings for Seed Selection in Complex Networks: Balancing Costs and Coverage

“…Research in this area is, among others, related to information flow within the networks [11], factors affecting performance of marketing campaigns [12] and the selection of highly influential nodes [13]. Campaigns based on information spreading can be targeted to increase the number of customers reached within the network [14], or alternatively can have quite the opposite goal, namely, to decrease disease transmission [15]. Models from epidemic research, such as SIR (Susceptible-Infected-Recovered) or SIS (Susceptible-Infected-Susceptible) [16], were implemented for the purposes of analyzing the spread of information with their extensions targeted to indirect and direct transmission [17] or heterogeneous networks [18].…”

Mathematical modeling of the propagation of malware: a review

“…Accordingly, in models exploring malware, we can find the same compartment. Thus, proposals have been made for SIS (see, for example, ), SIR (see, for example, ), SEIR (see, for example, ), SEIRS , SEIQS , SEIQRS , SEIRS‐V , SEIS‐V , SEIQV , SIRS , SEI , SIC , SIRQ , and so on. It may be seen that there is no single compartmental model that has been addressed in a greater number of works but that there is a certain homogeneity in the compartmental models proposed.…”

Numerical treatment of nonlinear model of virus propagation in computer networks: an innovative evolutionary Padé approximation scheme

“…Over the years several compartmental models have been evolved. These involve susceptibleinfected-susceptible (SIS) models [10,11], susceptible-infected-recovered (SIR) [12][13][14], susceptible-infected-recovered-susceptible (SIRS) [15,16], susceptible-exposed-infectedrecovered (SEIR) [17,18], SEIQS (quarantined class included) [19], SEIRS [20,21], SEIQRS [22], SEIRS-V (including vaccinated subpopulation) [23] models and so on.…”
