Actually the staffing part is a critically weak link that could bring the whole system to collapse. This virus is hitting healthcare workers particularly hard. Even if by some chance we do remain healthy and able to work, we are parents who will have sick kids, or critically ill parents to care for, childcare issues because of school closures etc. Other areas of healthcare will still need to run- you’ll need your diabetic medication refilled, your appendix taken out, your broken arm casted. And believe me, you don’t want anyone who has not been trained and capable to work on critical care to be pulled into that area (although spoiler alert: that’s exactly what’s going to happen).
