Age-specific transmission dynamics of SARS-CoV-2 during the first two years of the pandemic
Otilia Boldea, Amir Alipoor, Sen Pei +2
During its first two years, the SARS-CoV-2 pandemic manifested as multiple waves shaped by complex interactions between variants of concern, non-pharmaceutical interventions, and t…
Impact of commuting on disease persistence in heterogeneous metapopulations
Ganna Rozhnova, Ana Nunes, Alan J. McKane
We use a stochastic metapopulation model to study the combined effects of seasonality and spatial heterogeneity on disease persistence. We find a pronounced effect of enhanced pers…
Modeling the long term dynamics of pre-vaccination pertussis
Ganna Rozhnova, Ana Nunes
The dynamics of strongly immunizing childhood infections is still not well understood. Although reports of successful modeling of several incidence data records can be found in the…
Stochastic effects in a seasonally forced epidemic model
Ganna Rozhnova, Ana Nunes
The interplay of seasonality, the system's nonlinearities and intrinsic stochasticity is studied for a seasonally forced susceptible-exposed-infective-recovered stochastic model. T…
Cluster approximations for infection dynamics on random networks
Ganna Rozhnova, Ana Nunes
In this paper, we consider a simple stochastic epidemic model on large regular random graphs and the stochastic process that corresponds to this dynamics in the standard pair appro…
Population dynamics on random networks: simulations and analytical models
Ganna Rozhnova, Ana Nunes
We study the phase diagram of the standard pair approximation equations for two different models in population dynamics, the susceptible-infective-recovered-susceptible model of in…
SIRS dynamics on random networks: simulations and analytical models
Ganna Rozhnova, Ana Nunes
The standard pair approximation equations (PA) for the Susceptible-Infective-Recovered-Susceptible (SIRS) model of infection spread on a network of homogeneous degree predict a…
Fluctuations and oscillations in a simple epidemic model
Ganna Rozhnova, Ana Nunes
We show that the simplest stochastic epidemiological models with spatial correlations exhibit two types of oscillatory behaviour in the endemic phase. In a large parameter range, t…
