"As you can see, the Delta variant has a 0.1% case fatality rate (CFR) out of 31,132 Delta sequence infections confirmed by investigators. That is the same rate as the flu and is much lower than the CFR for the ancestral strain or any of the other variants. And as we know, the CFR is always higher than the infection fatality rate (IFR), because many of the mildest and asymptomatic infections go undocumented, while the confirmed cases tend to have a bias toward those who are more evidently symptomatic.
"In other words, Delta is literally the flu with a CFR identical to it. This is exactly what every respiratory pandemic has done through history: morphed into more transmissible and less virulent form that forces the other mutations out since you get that one. Nothing about masks, lockdowns, or experimental shots did this. To the extent this really is more transmissible, it's going to be less deadly, as is the case with the common cold. To the extent that there are areas below the herd immunity threshold (for example, in Scotland and the northwestern parts of the U.K.) they will likely get the Delta variant (until something else supplants it), but fatalities will continue to go down."
