Contact Tracing Evaluation for COVID-19 Transmission during the Reopening Phase in a Rural College Town

Category: Article Summary

Topic: Modeling and Prediction

• [pre-print, not peer-reviewed] Moon and Scoglio built an individual-based contact network model and a compartmental transmission model for COVID-19. They coupled these models to assess the effectiveness of contact tracing for COVID-19 control under four different re-opening strategies ranging from 0% to 75% of contacts traced. They found tracing 20% of contacts is enough to reduce the epidemic size by half under all strategies, and that above a threshold, increasing effectiveness of contact tracing results in a smaller number of quarantined individuals due to a reduced number of confirmed cases.
