Generation time in a discrete epidemic model with asymptomatic carriers: beyond geometric waiting times
Jordi Ripoll, Joan Saldaña
We study the random times between successive cases in a transmission chain of infectious diseases with asymptomatic carriers. We derive the probability distribution of this generat…
Collinear Fractals and Bandt's Conjecture
Bernat Espigule, David Juher, Joan Saldaña
For a complex parameter outside the unit disk and an integer , we examine the -ary collinear fractal , defined as the attractor of the iterated function syste…
Generalized epidemic model incorporating non-Markovian infection processes and waning immunity
Qihui Yang, Joan Saldaña, Caterina Scoglio
The Markovian approach, which assumes exponentially distributed interinfection times, is dominant in epidemic modeling. However, this assumption is unrealistic as an individual's i…
Saddle-node bifurcation of limit cycles in an epidemic model with two levels of awareness
David Juher, David Rojas, Joan Saldaña
In this paper we study the appearance of bifurcations of limit cycles in an epidemic model with two types of aware individuals. All the transition rates are constant except for the…
Robustness of behaviourally-induced oscillations in epidemic models under a low rate of imported cases
David Juher, David Rojas, Joan Saldaña
This paper is concerned with the robustness of the sustained oscillations predicted by an epidemic ODE model defined on contact networks. The model incorporates the spread of aware…
SIS Epidemics in Multilayer-based Temporal Networks
Aram Vajdi, David Juher, Joan Saldana +1
To improve the accuracy of network-based SIS models we introduce and study a multilayer representation of a time-dependent network. In particular, we assume that individuals have t…
Oscillations in epidemic models with spread of awareness
Winfried Just, Joan Saldana, Ying Xin
We study ODE models of epidemic spreading with a preventive behavioral response that is triggered by awareness of the infection. Previous studies of such models have mostly focused…
A network epidemic model with preventive rewiring: comparative analysis of the initial phase
Tom Britton, David Juher, Joan Saldana
This paper is concerned with stochastic SIR and SEIR epidemic models on random networks in which individuals may rewire away from infected neighbors at some rate (and reconnect…
Impact of density-dependent migration flows on epidemic outbreaks in heterogeneous metapopulations
Jordi Ripoll, Albert Avinyó, Marta Pellicer +1
We investigate the role of migration patterns on the spread of epidemics in complex networks. We enhance the SIS-diffusion model on metapopulations to a nonlinear diffusion. Specif…
Creating and controlling overlap in two-layer networks. Application to a mean-field SIS epidemic model with awareness dissemination
David Juher, Joan Saldaña
We study the properties of the potential overlap between two networks sharing the same set of nodes (a two-layer network) whose respective degree distributions $p_A(k), p…
Analysis of an epidemic model with awareness decay on regular random networks
David Juher, Istvan Z. Kiss, Joan Saldana
The existence of a die-out threshold (different from the classic disease-invasion one) defining a region of slow extinction of an epidemic has been proved elsewhere for susceptible…
