Something I meant to say upthread slightly and didn't: It seems like the nature of the overloading is different. In particular, from those reports you mentioned, it doesn't seem like staff had to decide which patients to treat or not. With COVID-19 we are hearing reports of some patients not being treated because there is not enough capacity (either staff or equipment) and so the death rates can be very high as many people receive inadequate treatment.
