The Australian and New Zealand governments have recently released smartphone-based apps to complement contact tracing in the event that they face a resurgence o 
User Experiences of the NZ COVID Tracer App in New Zealand: Thematic Analysis of Interviews
Appeals to civic responsibility are likely to drive the use of a mobile contact tracing app under the conditions of high threat, and flexible privacy settings in mobileContact tracing apps allowing users to set their optimal levels of privacy may be appropriate.
The more the merrier! Barriers and facilitators to the general public's use of a COVID-19 contact tracing app in New Zealand.
Technical, user, business, and government factors influenced the public's use of a COVID-19 contact tracing app in New Zealand and the development of apps requiring minimal user effort and initial user testing may improve uptake.

Four Covid-19 tracing applications were tested using MobSF and drozer to check for risks in the code (static analysis) and determine potential attack surfaces, including the OWASP mobile top 10 issues, as well as the CWE that were detected usingMobSF.
New Zealand's COVID‐19 elimination strategy
New Zealand’s “go early, go hard” approach to elimination in response to the coronavirus disease 2019 pandemic surprised many, but there were compelling reasons for NZ to pursue elimination.
The prevalence and clinical significance of Presymptomatic COVID-19 patients: how we can be one step ahead in mitigating a deadly pandemic
A retrospective study to look at the prevalence of presymptomatic patients with COVID-19 from data sourced via the medical records office and identifies early indicators of infection through demographic information, biochemical and radiological abnormalities which would allow early diagnosis and isolation.
Satellite-Based Personal UV Dose Estimation
This paper presents a new approach to estimate UV doses without the use of dosimeters by combining new satellite-derived UV data to account for environmental factors and simulation-based exposure ratio (ER) modelling to accounts for individual factors, and is able to estimate doses for specific exposure periods.


Financial Incentives for Downloading COVID–19 Digital Contact Tracing Apps
In this experiment, financial incentives were more than twice as important in the decision-making process about DCT app downloads than privacy and accuracy, and US States planning to launch digital contact tracing apps should consider offering financial incentives for download to potential users.
Modeling Contact Tracing Strategies for COVID-19 in the Context of Relaxed Physical Distancing Measures
This mathematical modeling study examines the potential for contract tracing to reduce the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the context of reduced physical
Peer-to-Peer Contact Tracing: Development of a Privacy-Preserving Smartphone App
The proposed smartphone-based contact tracing method presents a novel solution that preserves privacy while demonstrating the potential to suppress an epidemic or pandemic outbreak.
Digital Health Innovation: Exploring Adoption of COVID-19 Digital Contact Tracing Apps
With the outbreak of COVID-19, contact tracing is becoming a used intervention to control the spread of this highly infectious disease This article explores an individual's intention to adopt
Evolving Epidemiology and Impact of Non-pharmaceutical Interventions on the Outbreak of Coronavirus Disease 2019 in Wuhan, China
Considerable countermeasures have effectively controlled the Covid-19 outbreak in Wuhan, China, and special efforts are needed to protect vulnerable populations, including healthcare workers, elderly and children.

A simple relationship is found between the efficiency of contact tracing necessary for eradication and the basic reproductive ratio of the disease, and this holds for a wide variety of realistic situations including heterogeneous networks containing core–groups or super–spreaders, and asymptomatic individuals.
Outbreak analytics: a developing data science for informing the response to emerging pathogens
The most common analytics components, their inter-dependencies, data requirements and the type of information they can provide to inform operations in real time are critically reviewed.
