The following post summarizes key findings from the article ‘Impact of delays on effectiveness of contact tracing strategies for COVID-19: a modeling study’ published by The Lancet Public Health. The piece is written by Dr. Mirjam E Kretzschmar, Dr. Ganna Rozhnova, Dr. Martin C J Bootsma, Dr. Michiel van Boven, Dr. Janneke H H M van de Wijgert, and Dr. Marc J M Bonten. Read on to explore the importance of a contact tracing solution in the effectiveness of containing the spread of COVID-19.

The article explored the impact of delays in tracing and testing to effective contact tracing. Additionally, it examined and compared the effectiveness of manual contact tracing and mobile app-based contact tracing. 

You do not want a delay in COVID-19 testing

It is important to minimize the time between symptom onset and receiving a positive test result in order to prevent further infections. The article asserts that minimizing testing delay is crucial to improving contact tracing effectiveness, assuming immediate isolation following a test result. Our daily screening application will prompt employees to stay at home and see a doctor immediately after they report COVID-19 symptoms. Additionally, users can directly report positive test results within the application to notify administrators.

You do not want a delay in contact tracing

Decreasing the amount of time it takes to trace contacts is incredibly important to reducing overall COVID-19 transmission. The article found that shortening this time interval boosted the efficacy of contact tracing. In the study, they assumed the person immediately sought testing and then isolated, if positive. Our contact tracing application allows users to log who they’ve been in contact with. Additionally, through our BioSecurity Portal, administrators can see who a positive case has been in contact with, automatically via Bluetooth tracking and can then notify those who were potentially exposed.

App-Based Contact Tracing vs Manual Contact Tracing 

Overall, they found mobile app-based contact tracing to be more effective than conventional contact tracing because of the application’s quick response capabilities. One interesting case they did not study in this piece was a hybrid approach with conventional and app-based contact tracing systems. ReturnSafe’s solution provides you with an app-based solution. However, through our Partnership with TaskUs, you also have access to manual tracing options. With our solution, your administrators have all the tools they need to effectively control and contain the COVID-19 outbreak and keep employees safe.

What factors may negatively impact contact tracing? 

The article also identified hindrances to effective contact tracing. Amongst these were a significant number of undiagnosed or asymptomatic cases and untraceable contacts.

How can you reduce the impact of these factors?

App-based screening and contact tracing solutions can increase the number of traceable contacts and diagnosed cases. However, to do this, there must be substantial participation, application acceptance, and sustained usage. What does that mean? Your employees should feel the application is built for their safety to encourage user participation. Our solution is crafted by experts in UX design and app development to optimize the users experience. How do you know if your application is widely accepted? Through our BioSecurity Portal administrators can directly monitor screening compliance.

Our goal is to empower the employees and the organization to stay safe. So we created features that allow users and administrators to maximize the effectiveness of contact tracing. Every measure your organization takes to prevent infection will lower the overall number of cases and contain the outbreak.
