This has been a topic of discussion a fair amount lately, especially with kids going back to school and the POTUS’ testing positive for Covid-19. How long does one quarantine for?

For instance, wearing a mask reduces risk but doesn’t eliminate it. It is the same with distancing. 6ft may not be sufficient
