About the app

The application provides a graphical user interface (UI) that presents the estimated benefits of a given asymptomatic testing strategy, as well as untangling interactions between vaccination and testing benefits. It allows interested users with advanced knowledge to create risk profiles that illustrate relationships between risk, interventions, and projection assumptions. It is based on the {covidscreen}, which is an R package designed to help organizations evaluate their risk from COVID-19 and the potential benefits of regular asymptomatic testing. The simulation use information on community case rates, asymptomatic-to-symptomatic case ratio, and assumed infectiousness periods to estimate the reduction in active cases on campus achieved by regular asymptomatic testing.
