Dr. Michael Mina:

Quarantine is very destructive. If we quarantine people all the time, it is very difficult. These tests can be used as an alternative. If we were to test whether someone has had exposure or if he or she is just arriving into another country, these tests can be used every day, instead of quarantine. A test used every day will probably be more effective than quarantine, particularly when we start to consider the fact that people in quarantine tend to become non-compliant after a few days. That has to be taken into account, and a test used every day will be a very effective substitute for a quarantine of somebody who is not known to have been infected.
