Like the McCormick Place in Chicago, everything that was used to treat and touch patients was brought in and subsequently removed. Patients weren't sleeping on the floor, which is all that is left of those treatment areas. With a hotel, you'd have to rip everything out - the beds, desks, carpet, etc - and the walls/bathrooms are permanent structures where they were temporary structures at the McCormick Place and subsequently removed. Just bleach the floors and you're good to go. The air will get circulated through filters which, like airplanes, filter out viruses. Very likely. There is no shortage of hospital beds, which is why the McCormick Place/Javitz Center/Navy Ships were shut down. As of yesterday, Illinois was only using 25% of hospital beds for COVID patients and only 25% of their 3,000+ ventilators. Last week, the mayor of Austin, TX, said that over the last 20-30 days hospitalizations were down over 90%.
