The COVID-19 pandemic has seen digital contact tracing emerge around the world to help prevent spread of the disease. A mobile phone app records proximity events between app users, and when a user tests positive for COVID-19, their recent contacts can be notified instantly. Theoretical evidence has supported this new public health intervention1-6, but its epidemiological impact has remained uncertain7. Here we investigated the impact of the NHS COVID-19 app for England and Wales, from its… 
Effectiveness of digital contact tracing for COVID-19 in New South Wales, Australia
TLDR
COVIDSafe was not sufficiently effective to make a meaningful contribution to the COVID-19 response in Australia's most populous state over a 6-month period, and there is no evidence that it adds value to conventional contact tracing.
The epidemiological impact of the Canadian COVID Alert app
TLDR
The effectiveness of the Canadian COVID Alert app, when adopted at sufficient levels, can be an effective public health tool for combatting a pandemic such as COVID-19.
The effect of notification window length on the epidemiological impact of COVID-19 contact tracing mobile applications
TLDR
An epidemiological model of SARS-CoV-2 transmission is used that captures the profile of infection to consider the trade-off between notification window length and active app-usage, demonstrating the importance of understanding adherence to control measures when setting notification windows for COVID-19 apps.
Nationwide rollout reveals efficacy of epidemic control through digital contact tracing
TLDR
A unique real world contact data set, collected during the rollout of the first Norwegian contact tracing app in the Spring of 2020, is used to address the evidence on its effectiveness and help informing public health policies in the coming months.
Nationwide rollout reveals efficacy of epidemic control through digital contact tracing
TLDR
Using a unique real world contact data set, collected during the rollout of the first Norwegian contact tracing app in the Spring of 2020, digital tracing can flag individuals with excessive contacts and can help contain superspreading related outbreaks.
Characterization of unlinked cases of COVID-19: Implication on contact tracing measures.
TLDR
The unlinked cases were positively associated with the time to hospital admission, severity of infection, and epidemic size - implying a need to design and implement digital tracing methods to complement current conventional testing and tracing.
“Immuni” and the National Health System: Lessons Learnt from the COVID-19 Digital Contact Tracing in Italy
TLDR
Digital contact tracing through mobile phone apps in Italy has had little adoption across the Italian population, and the recent increase in its download is likely to be related to the mandatory Green Pass certification for conducting most daily activities that can be obtained via the application.
The First GAEN-Based COVID-19 Contact Tracing App in Norway Identifies 80% of Close Contacts in “Real Life” Scenarios
TLDR
The Norwegian Google Apple exposure notification (GAEN)-based contact tracing app Smittestopp v2 was evaluated under relevant “real-life” test scenarios and the results were used to improve and evaluate the performance of the Norwegian contact-tracing app SmITTestopp.
Digital contact tracing contributes little to COVID-19 outbreak containment
TLDR
It is found that contact tracing does not change the epidemic threshold and exclusively prevents more cases during the supercritical phase of an epidemic, making it unfit as a tool to prevent outbreaks.

Early Evidence of Effectiveness of Digital Contact Tracing for SARS-CoV-2 in Switzerland
TLDR
It is demonstrated proof-of-principle that digital contact tracing reaches exposed contacts, who then test positive for SARS-CoV-2, indicating thatdigital contact tracing is an effective complementary tool for controlling the spread of Sars-Cov-2.
Quantifying SARS-CoV-2 transmission suggests epidemic control with digital contact tracing
TLDR
A mathematical model for infectiousness was developed to estimate the basic reproductive number R0 and to quantify the contribution of different transmission routes and the requirements for successful contact tracing, and the combination of two key parameters needed to reduce R0 to less than 1 was determined.
The timing of COVID-19 transmission
TLDR
For symptomatic individuals, the timing of transmission of SARS-CoV-2 is more strongly linked to the onset of clinical symptoms of COVID-19 than to the time since infection, and the pre-symptomatic infectious period extended further back in time for individuals with longer incubation periods.
Modeling the combined effect of digital exposure notification and non-pharmaceutical interventions on the COVID-19 epidemic in Washington state
TLDR
In a model in which 15% of the population participated, it is found that digital exposure notification systems could reduce infections and deaths by approximately 8% and 6%, effectively complementing traditional contact tracing.
Modeling the effect of exposure notification and non-pharmaceutical interventions on COVID-19 transmission in Washington state
TLDR
Individual-based models of three Washington state counties are created to explore how digital exposure notifications combined with other non-pharmaceutical interventions influence COVID-19 disease spread under various adoption, compliance, and mobility scenarios and found that exposure notification could reduce infections and deaths by approximately 8% and 6% and could effectively complement traditional contact tracing.
Digital Proximity Tracing in the COVID-19 Pandemic on Empirical Contact Networks
TLDR
This work investigates how well contact tracing apps, coupled with the quarantine of identified contacts, can mitigate the spread of COVID-19 in realistic scenarios such as a university campus, a workplace, or a high school and confirms that a high level of app adoption is crucial to make digital contact tracing an effective measure.
A population-based controlled experiment assessing the epidemiological impact of digital contact tracing
TLDR
A 4-week population-based controlled experiment that took place in La Gomera between June and July 2020, where the epidemiological impact of the Spanish DCT app Radar Covid was assessed, provides experimental evidence of the potential usefulness of DCT during an epidemic outbreak in a real population.
Estimating the effects of non-pharmaceutical interventions on COVID-19 in Europe
TLDR
The results show that major non-pharmaceutical interventions and lockdown in particular have had a large effect on reducing transmission and continued intervention should be considered to keep transmission of SARS-CoV-2 under control.
OpenABM-Covid19 - an agent-based model for non-pharmaceutical interventions against COVID-19 including contact tracing
TLDR
OpenABM-Covid19 is presented: an agent-based simulation of the epidemic including detailed age-stratification and realistic social networks and its Python interface has allowed scientists and policymakers to simulate dynamic packages of interventions and help compare options to suppress the COVID-19 epidemic.
