The voice of reason.
I would add that any building used for China virus treatment will need thorough sterilization ($$) afterward. If (say) a hotel was used for that purpose, it’s likely that their business would take a huge hit ($$$) for several months to come afterward — regardless of whether or not the building is actually totally disease-free*. Hospitals are designed to allow for sterilization — the materials used in hotels aren’t the same.
I’m aware that the virus has a limited ‘life’ on surfaces — but, public perception will matter more.
I can see where someone with a run-down third tier hotel would jump at the chance. But they would need to move out the furniture and store it (or replace it afterwards) to put in hospital furnishings - unless they just had large ballrooms to convert. Probably would want to rip out the carpeting and go to bare concrete as well.
I stayed at one of the old Statler hotels a few weeks before it was finally closed and torn down. Given its condition at the time and the future plans, it would have made a good candidate if the timing had coincided.
