The problem is that the number of people who need intensive care is quite high (10-20%) if good health care can be provided to them the mortality stays low, however, if the hospitals are overrun a lot of people would not get it and could potentially die (yes even younger people). And trust me no health care can survive a 300% spike in people needing ICU. So it is not that harmless.
