Regarding capacity, hospitals are designed to run at 90% capacity -- the state literally limits the number of hospitals in regions to ensure this is the case (i.e. hospitals stay profitable). ICU capacity is often at 100% and if you know anyone working in ICUs (I have multiple family members) this isn't new.
That being said, they will increase turn-over by reducing their current care level, etc.
Also should note, I can't help but feel this focus on Florida, Texas, Arkansas, etc is because they have banned masks and vaccine mandates.
If you look at actual hospitalizations and more importantly death rates you see something different: https://www.statista.com/statistics/1109011/coronavirus-covi...
