We have some of those prefab container "room" buildings. They are referred to as "barracones", they were mostly built during the civil war and were intended as temporary. Since spain is a democracy it is absolutely illegal to house people in them. They're mostly used as warehouses and offices, and even then only for personnel that typically doesn't spend most of their time in the office, like cleaning personnel and shit like that. The most use they got was one module used as a school during the camps administration and people fucking RIOTED. I have seen the working conditions in there, and it gets so bad that pens stop working in winter due to freezing and can explode during the summer. They are THAT hard to isolate. And we're talking about areas with fairly mild temperature nothing inland where shit gets dry. The idea of making an entire hospital out of the bloody thing to keep people for prolongued periods of time is nightmarish, that's no hospital it's a quarantine deathcamp.
This is why I hate the 5000yo culture propaganda. Yeah, here in spain we can trace our culture since the iberians, phoenicians, romans, visigoths, etc. All the way from the stone ages, but we don't have a 5000yo culture, because we CHANGED WHAT DIDN'T WORK. Back in ww2 eith franco in charge we built shit like that, but we got better, we took out the bad and adapted to european advances, because we know if culture is bad for the population then it should be kicked to the curb in favor of what works, my problem with china isn't how horrifying their past is, it's that they refuse to learn, and these "hospitals" are yet further proof of that.
