COVID-19 Test Frequency versus Test Sensitivity in Disrupting SARSCoV-2 Transmission: A Review of Statistical Modeling Simulations

Justin Rogers, Laurel Jackson, Adam Buss, Susan H. Gawel

Objectives: This paper presents a statistical review of modelling simulations for frequency and sensitivity of COVID-19 testing paradigms.

Methods: We performed a review of preprints and published articles on PubMed from January 1, 2020-March 1, 2021 using the search terms “COVID screening testing”, “COVID testing frequency”, “COVID testing frequency screening” and “SARS-CoV-2 testing frequency”.

Results: Several authors’ conclusions support the claim that test frequency and test sensitivity both play a role in reducing SARS-CoV-2 transmission. We highlight the interplay between frequency of testing, test sensitivity and the speed at which test results are available in our review.

Conclusion: Evidence suggests that sensitivity and frequency of testing both play a part in decreasing transmission of disease. We conclude that, overall, test sensitivity plays less of a role in reducing disease transmission in a population compared to the frequency of testing and how quickly test results are available.
