Oh my fucking God!!
of course there’s a significant difference. The 0.1% for Flu is across EVERYONE THAT IS INFECTED just like the 3.4% for Covid-19 is.
So if you’re under 40 and get Flu, you don’t have a 0.1% of dying, you have a 0.01% chance of dying (compared with 0.2% of Covid-19, more than double an order of magnitude).
It is at least an order of magnitude more lethal. I don’t know any other way of explaining this to you, you can’t compare under 40’s with Covid-19 against the “whole population” that gets Flu and say they’re comparable. They’re not.
It’s posts like yours that are so fucking frustrating because you don’t understand maths, epidemiology, fatality rates across demographics and, it seems, basic English comprehension.
Italy are not plunging themselves into a recession for something only as lethal as the fucking Flu.
