We study the susceptible‐infective‐recovered (SIR) epidemic on a random graph chosen uniformly subject to having given vertex degrees. In this model infective vertices infect each of their susceptible neighbours, and recover, at a constant rate. Suppose that initially there are only a few infective vertices. We prove there is a threshold for a parameter involving the rates and vertex degrees below which only a small number of infections occur. Above the threshold a large outbreak occurs with…

We consider a stochastic SIR (susceptible $\to$ infective $\to$ recovered) epidemic defined on a configuration model random graph, in which infective individuals can infect only their neighbours in

Near-critical SIR epidemic on a random graph with given degrees

This paper studies near-critical behaviour in the context of a susceptible-infective-recovered epidemic on a random (multi)graph on n vertices with a given degree sequence, and determines the probability that a large epidemic occurs, and the size of alarge epidemic.

Epidemics on critical random graphs with heavy-tailed degree distribution

We study the susceptible-infected-recovered (SIR) epidemic on a random graph chosen uniformly over all graphs with certain critical, heavy-tailed degree distributions. For this model, each vertex

SIR epidemics and vaccination on random graphs with clustering

An important special case of the epidemic model analysed in this paper is epidemics in continuous time with arbitrary infectious period distribution, and it is found that R_0$$R0 equals the perfect vaccine-associated reproduction number.

Heterogeneous network epidemics: real-time growth, variance and extinction of infection

This work considers the early real-time behaviour of the Markovian SIR epidemic model on a configuration model network using a multitype branching process and finds closed-form analytic expressions for the mean and variance of the number of infectious individuals as a function of time and the degree of the initially infected individual(s).

The large graph limit of a stochastic epidemic model on a dynamic multilayer network

A large graph limit theorem is derived that gives a system of ordinary differential equations (ODEs) describing the evolution of quantities of interest, such as the proportions of infected and susceptible vertices, as the number of nodes tends to infinity.

A stochastic SIR network epidemic model with preventive dropping of edges

The results are specialised to the model without dropping of edges to yield conjectured central limit theorems for the final size of Markovian SIR epidemics on configuration-model networks, and for the size of the giant components of those networks.

A functional central limit theorem for SI processes on configuration model graphs

We study a stochastic compartmental susceptible–infected (SI) epidemic process on a configuration model random graph with a given degree distribution over a finite time interval. We split the

Pandemic Risks and Equilibrium Social Distancing in Heterogeneous Networks

The equilibrium of the social distancing game is studied and it is shown that voluntary social Distancing will always be socially sub-optimal and the absolute and relative utility gaps across age cohorts are quantified.

Epidemics on networks with preventive rewiring

A stochastic SIR (susceptible → infective → recovered) model is considered for the spread of an epidemic on a network, described initially by an Erdős–Rényi random graph, in which susceptible



Graphs with specified degree distributions, simple epidemics, and local vaccination strategies

Consider a random graph, having a prespecified degree distribution F, but other than that being uniformly distributed, describing the social structure (friendship) in a large community. Suppose that

Large graph limit for an SIR process in random network with heterogeneous connectivity

We consider an SIR epidemic model propagating on a Configuration Model network, where the degree distribution of the vertices is given and where the edges are randomly matched. The evolution of the

Contact processes on random graphs with power law degree distributions have critical value 0

If we consider the contact process with infection rate λ on a random graph on n vertices with power law degree distributions, mean field calculations suggest that the critical value λ c of the

The dynamic equations provide an alternative way of determining the epidemic threshold where large-scale epidemics are expected to occur, and below which epidemic behavior is limited to finite-sized outbreaks.

This paper shows that a large class of standard epidemiological models, the so-called susceptible/infective/removed (SIR) models can be solved exactly on a wide variety of networks.

SIR epidemics on random graphs with a fixed degree sequence

The likely evolution in continuous time of the SIR model for the spread of an infectious disease on Gz, starting from a single infected node is determined, finding the epidemic is likely to follow a trajectory given by the solution of an associated system of ordinary differential equations.

A note on a paper by Erik Volz: SIR dynamics in random networks

An alternate derivation which arrives at a simpler—though equivalent—system of governing equations to that of Volz is offered, which is more closely connected to the underlying physical processes, and the resulting equations are of comparable complexity to the mass-action SIR equations.

Approximating the epidemic curve

Many models of epidemic spread have a common qualitative structure.  The numbers of infected individuals during the initial stages of an epidemic can be well approximated by a branching process,
