Optimal COVID-19 Quarantine and Testing Strategies



Keywords (Tags):

  • [Pre-print, not peer reviewed] A mathematical model found that a 13-day quarantine with testing on entry, a 9-day quarantine with testing on exit, and an 8-day quarantine with testing on entry and exit all provide equivalent or lower probability of post-quarantine transmission compared to a 14-day quarantine with no testing. When limited to a single test, testing on day six or seven was optimal regardless of quarantine length.
