Vaccination strategies of a modified SIS model on complex networks
نویسندگان
چکیده
A new susceptible-infected-susceptible model is researched in this paper, which has an infective vector. And it describes epidemics (e.g. malaria) transmitted through an infective vector (e.g. mosquitoes) on complex networks. We compare the modified model with the standard SIS model having an infective vector. We also study and compare the effects of the uniform immunization and targeted immunization on complex networks. Then, analytical and simulated results are given to show that the uniform immunization strategy to the modified model is very effective on scale-free networks. Keywords— Complex network, Disease spread, Immunization, Infective vector.

Epidemic spreading with time delay in complex networks
We present a modified susceptible-infected-susceptible (SIS) model on complex networks, small-world and scale-free, to study epidemic spreading with the effect of time delay which is introduced to the infected phase. Considering topologies of the networks, both uniform and degree-dependent delays are studied during the contagion process. It is found that the existence of delay will enhance both...
متن کاملComparison of mean-field based theoretical analysis methods for SIS model
Epidemic spreading has been intensively studied in SIS epidemic model. Although the mean-field theory of SIS model has been widely used in the research, there is a lack of comparative results between different theoretical calculations, and the differences between them should be systematically explained. In this paper, we have compared different theoretical solutions for mean-field theory and ex...
متن کاملEffect of Small-World Networks on Epidemic Propagation and Intervention
The small-world network, characterized by special structural properties of high connectivity and clustering, is one of the highlights in recent advances in network science and has the potential to model a variety of social contact networks. In an attempt to better understand how these structural properties of small-world networks affect epidemic propagation and intervention, this article uses a...
متن کاملEpidemics among a Population of Households
This paper considers SIR and SIS epidemics among a population partitioned into households. This heterogeneity has important implications for the threshold behaviour of epidemics and optimal vaccination strategies. It is shown that taking into account household structures when modelling public health problems is valuable. An overview of households models is given, including a determination of th...
