Sorry to hear about your dad's kidneys, but you're inflating the impact of COVID patients on other patients.
If COVD patient A has no or minor symptoms, they go home and isolate. No hospital bed needed.
If COVID patient B is having a way worse time with COVID, they are normally placed on a respirator in the ICU. That's my understanding, but I'm sure there are exceptions.
Your father would not be in an ICU. If he's admitted for chemo, he'll get a regular room to rest in between therapy sessions. If he's not that bad, he could also receive chemo treatments as an outpatient, just showing up for the chemo and going back home.
The main reason beds is an issue for COVID is because there are so few ICU-equipped beds, not that there are COVID patients taking up all the regular hospital beds.
Even in NY, when Cuomo was crying about so many patients overwhelming the hospitals, they didn't use a single bed in the stadium "hospital" or the hospital ship Trump sent there for NY to use.
Don't believe the doom and gloom stories you're being fed. I'm sure some are true -- to a point. Most I have a feeling are blown way out of proportion.
I've noticed in today's victim-loving society, people love to exaggerate their plights.
