Also worth noting is that people were asked to postpone elective surgeries during this crisis, so that could be part of the reason for some of the hospitals looking underutilized.
Another indication of what you said...my daughter works for a company that processes medical billing and their volume is way down...to the point where they may have to lay off some people.
Elective stuff is shut down, and lower level things like sprained ankles and broken fingers are shying away from medical care right now.
