The OP didn't say "per year". You added that one gratuitously.

It makes no difference at all. But whatever set of statistics you use has to represent the same period. We could use daily deaths from flu, or decadal deaths from flu, or forthnightly deaths from flu .. as long as the total deaths we're comparing with cover the same period.

Thanks for this breakdown, I was too tired to protest but I completely agree with your interdiction.

I mean, I began by saying:

> the IFR of the seasonal flu is around 0.1%

We're all going to die some day. Based on current causes of death, there's a 20% chance, give or take, that it will be heart disease. A 20% chance it will be cancer. A 2% chance one of us will die from kidney failure. And around a 1.5% chance it will be from the seasonal flu, which has an IFR of 0.1% or less.

Anyway, bringing this back around to the Spanish flu, it's fascinating, to me, that if you were alive in 1918, there was around a 1% chance you would die, that year, of the Spanish flu, and around a 2% chance you would die, years or decades later, of a seasonal flu. Pandemics get you upfront, all at once, epidemics get us eventually, over time.
