The Usefulness Of SARS-CoV-2 Test-Positive Proportion As A Surveillance Tool

Category: Article Summary

Topic: Modeling and Prediction

Keywords (Tags): testing

The test-positive proportion (TPP), the proportion of tested individuals who have tested positive, may be informative in predicting trends in COVID-19 incidence. The TPP strongly correlated with incidence in simulation results, as long as testing resources were sufficient to cover symptomatic and asymptomatic testing up to 35 days. However, the correlation between TPP and incidence weakened as variance of testing availability increased.
