I think POTUS is using a map like this to determine how to restart the system by hospital overload estimates .
SEE MAP:
Limited Action
Public advocacy around “social distancing” and enhanced hygiene. Minimal mandated restrictions.
Social Distancing
Voluntary “shelter-in-place” for high-risk groups, schools and bars / restaurants closed.
Shelter in Place
Legal order or strong recommendation for citizens to employ “shelter-in-place” home quarantine (especially firm for high-risk groups), shutdown of non-essential businesses, ban on all group events.
