This isn't well supported by data. In the sense that (a) young people just aren't particularly affected any more so than with the flu (old and sick people of course are much worse off) and (b) in Italy's data, no health professionals under the age of 49 died. There have been some deaths outside Italy but on average the trend mirrors the broader trend: if you're young and healthy, you're just fine. [1, 2]
I get that there's wide-spread panic, but we should allow the data to guide us where it exists. This isn't the time to spout off unsubstantiated fear-inducing commentary.
We need to keep our wits about us if we're going to tackle this effectively.
