Correction to: Containing pandemics through targeted testing of households

Abstract

Following publication of the original article [1], it was noted that due to a typesetting error the figure legends were paired incorrectly.The caption of Fig. 1 belongs to Fig. 2. And the caption of Fig. 2 belongs to Fig. 1.The correct figures and captions have been included in this correction, and the original article has been corrected.

Comparing the impact of vaccination strategies on the spread of COVID-19, including a novel household-targeted vaccination strategy

“…The results in this article were obtained through the use of a multi-layer individual based epidemic model, previously described in [ 8 ]. Briefly, the model represents daily spread and progress of COVID-19 for a city with demographics similar to Oslo, Norway, with approx.…”

“…The disease dynamics in the model follow a typical extended SEIR model, in which any individual can be either susceptible, exposed, infected asymptomatic, infected pre-symptomatic, infected symptomatic, hospitalized or dead [ 8 ]. When a susceptible individual comes into contact with an infected person, there is a layer-dependent probability that the susceptible individual transitions to the exposed state.…”

“…As an individual transitions to any state except recovered or dead, the time spent in the new state as well as the following transition to be made is chosen at random according to a parameter table described in Ref. [ 8 ]. Recovery is assumed to provide immunity to further re-infection for at least the duration of the simulation.…”

“…Due to the multi-layer dynamics involved, a sudden change in parameters will lead to a transitional period of about 10 days until R stabilizes at the steady-state for the new parameter set, as described in Ref. [ 8 ] (Supplementary material).…”

“…This approach can therefore be considered to represent a mix of contact-reducing measures (such as avoidance of public venues) as well as as infection-reducing measures for the contacts that still happen (such as mask wearing). The other layers are kept at fixed infection probabilities with no particular restrictions (with the exception of symptomatic individuals self-isolating), corresponding to the pre-lockdown regime described in [ 8 ]. The relative proportion of random contacts is therefore variable across scenarios, with higher values of R having a higher share of infections taking place between random contacts.…”
