Instead of quarantine for Covid-exposed students, some schools are trying test-to-stay.

Cluster RCT: Daily contact testing of school-based contacts was non-inferior to self-isolation for control of COVID-19 transmission.

Kids are losing school days to quarantines. Here’s a way to keep them in classrooms – “Test-to-stay could dramatically reduce close contact quarantines”.

Opinion | Data from routine Covid testing can help schools stay open this year.
