When we talk about flu stats: most people have some immunity to the flu thanks to flu shots (even if they haven't gotten one for this past year) and general herd immunity, which we DO NOT HAVE for this virus, and won't gain without either a vaccine or a few million dead from this thing running rampant.
The stats you're quoting are WITH the level of serious intervention we've had so far, which is why as certain states are reopening, we're starting to see the numbers ticking back up again and looking just as bad if not worse.
