Ask HN: Why aren't hospitals prepared for a pandemic?

Having worked in fintech for many years, I have seen regulations require that firms prepare a multitude of ways to manage or recover from large-scale emergencies. As current anecdata, I haven't heard of any issues with the unprecedented demands placed on firms for those who are now working from home (toss a coin to your network admin).

Healthcare must be under similar, if not more stringent regulations and oversight. From what I've read SARS-CoV-2 was a foreseeable event. Why does healthcare give the impression of a lack of planning and are making it up as they go? What are we not seeing?
