Analysing the Effect of Test-and-Trace Strategy in an SIR Epidemic Model

  title={Analysing the Effect of Test-and-Trace Strategy in an SIR Epidemic Model},
  author={Dongni Zhang and Tom Britton},
Consider a Markovian SIR epidemic model in a homogeneous community. To this model we add a rate at which individuals are tested, and once an infectious individual tests positive it is isolated and each of their contacts are traced and tested independently with some fixed probability. If such a traced individual tests positive it is isolated, and the contact tracing is iterated. This model is analysed using large population approximations, both for the early stage of the epidemic when the ”tobe…

Stochastic epidemic models featuring contact tracing with delays.
Numerical illustrations show that, while the distributions of latent periods and delays have an effect on the spread of the epidemic, the assumption of whether the delays experienced by individuals infected by the same individual are of the same or independent length makes little difference.
Threshold behaviour of emerging epidemics featuring contact tracing
This paper is concerned with a stochastic model for the spread of an epidemic with a contact tracing scheme, in which diagnosed individuals may name some of their infectious contacts, who are then
Contact tracing in stochastic and deterministic epidemic models.
It is possible to obtain a deterministic model that approximates the stochastic process, and in this way, to determine the prevalence of disease in the quasi-stationary state and to investigate the dynamics of the epidemic.
Estimating the Tracing Probability from Contact History at the Onset of an Epidemic
The distribution of the total number of additionally detected persons per index case is derived, partially by heuristic arguments, and this distribution depends mainly on the tracing probability.
HIV with contact tracing: a case study in approximate Bayesian computation.
An original extension of ABC to path-valued summary statistics, corresponding to the cumulated number of detections as a function of time, is proposed, and the percentage of undetected infectious individuals is found to be of the order of 40%.
Bidirectional contact tracing could dramatically improve COVID-19 control
A stochastic branching-process model shows that “bidirectional” tracing to identify infector individuals and their other infectees robustly improves outbreak control and suggests that implementing bidirectional tracing could dramatically improve COVID-19 control.
Engagement and adherence trade-offs for SARS-CoV-2 contact tracing
An existing branching process model is used to examine an inverse relationship between self-isolation adherence and self-reporting engagement, and it is found that policies that increase the verage duration of self- Isolation, at the expense of reduced self- reporting rate, will not decrease the risk of a large outbreak and may increase the risk, depending on the strength of the trade-off.
An Elementary Proof of the Hitting Time Theorem
In this note, we give an elementary proof of the random walk hitting time theorem, which states that, for a left-continuous random walk on Z starting at a nonnegative integer k, the conditional
Contact Tracing&Super-Spreaders in the Branching-Process Model
Numerical analysis with parameters suited for SARS-CoV-2 indicates that super-spreaders do not decrease the effect of contact tracing crucially in case of that infection.
