Based on the input from our subject matter experts, the effects of testing for the disease and quarantining the infected are tightly coupled. Imagine if we did testing but did no quarantine - the infected people would still be able to infect others. If we did quarantine but no testing - that would be the same as applying a general stay at home order to everyone, which is handled in the Social Distancing Control Policy. So, testing and quarantine go hand in hand.
