In my humble opinion wake up calls were in 2003 SARS and 2009 H1N1, but we decided to ignore those, now we get the real thing, that has improved and evolved.
Note: I think it's fair to say, SK is/was ready or has responded well, patient 31 notwithstanding.
I think the USA needs to work on the basics, but other nations will have so interesting advanced strategic decisions. i.e. Does ventilator design changes frequently? Does it make sense to have an on-demand factory or just build up a stockpile of ventilators that can be distributed as needed?
