There is some merit to what you are saying, but the flu killed dozens of times as many vulnerable people in this area in the 2017 to 2018 season as this is likely to do even if things escalate dramatically. This is obviously not something to be trifled with but the hype on this is spectacular and the panic and fear is completely out of proportion to the actual risks.
I have wondered about this since the news about this facility became known. Our excellent advanced medical care can keep very frail people alive even though they usually cannot survive any kind of pneumonia.
I also think that we should be able to see a chart with aggregate information on age and underlying medical condition, including obesity and smoking status of every person who has died. It is possible that a pattern would be shown whereby people with certain risk factors could be assisted to self-isolate but the shutdown of an entire country would have been prevented.
