He is not getting better

I would say he is on Oxygen
but will not let anyone know of that fact.

Maybe, worth mentioning though that there's a difference between oxygen on demand via mask (which a lot of moderate cases benefit from) and being on full ventilator. There's also other reasons to be in, like being on fluids if the main issue is the fever. To keep things in perspective - it's worth remembering that 20% of cases need hospital treatment but only about 5% of cases are critical (needing ICU / ventilator). 3/4 of hospital treated cases are not critical so it's still more likely than not that he'll be OK - unless we hear that he's been transferred to ICU. That's when survival rate drops to 50/50.
