How does an IFR of 0.1-0.2% compare to the seasonal flu? I am not asking out of some agenda, I just want to have my facts straight. Even if the IFR is similar, we are obviously seeing much higher impact on the healthcare system than a normal flu season.

The 1918/19 pandemic flu had an CFR of 2.5% (though keep in mind that there was no molecular diagnostic that could diagnose everyone).  A typical pandemic flu has a CFR of <0.1%.  I'm also not sure of the ability of serology for influenza to differentiate between strains, so I don't know if the prevalence has ever been found that way.
