Dear God no. Please don't create a covid19 death ship. Covid19 has proven to be a ruthless killer on recycled air systems. It would be impossible to screen for the virus - it would certainly find it's way on board.
In that case, the best use might be the "isolate mild cases" approach: everyone who tests positive goes on the ship, even (especially) if they don't have symptoms. If they deteriorate to severe, move them to a real hospital. This has been a big part of the Wuhan campaign.
I doubt that. It’s more likely to depend on the viral load you’re exposed to. Being a nurse with inadequate PPE intubating someone and being exposed to large quantities of COVID once will give the virus a head start, whereas running through a cough cloud and just barely getting enough to infect you five times over the course of an hour will give your immune system a head start.
Many medical procedures have been pushed back, a bunch of surgeons twiddling their thumbs somewhere. Might be useful to have them operate out of retrofitted cruise medical ships.
The army core of engineers would have to heavily modify them. We do have hospital ships. I am not sure it'd be possible though to get negative pressure in the HVAC.. maybe.
