Controlling COVID-19 via Test-Trace-Quarantine



  • [Pre-print, not peer reviewed] Using detailed demographic, mobility, and epidemiological data for the Seattle region to calibrate an agent-based model, Kerr et al. assessed the requirements for implementing a successful “test-trace-quarantine” strategy and found that if high mask compliance and school closures remain in place, realistic levels of testing (~4,000 routine tests per day) and tracing (50% of all contacts traced within 2 days) are sufficient to maintain epidemic control despite full return to workplace and community mobility.
