"where the secondary rate of infection is indistinguishable from a prior rate of infection"

Where do you get that assertion?

If it is milder, why are the hospitals getting so many patients? Our treatment protocols are far advanced over last year. People go home sooner. And seniors are much better protected.

I've seen nothing that says that alpha and delta infect different people. Delta does not seem to escape the vaxes. But it has crushed alpha.

Almost every state has worse numbers than it did a year ago, despite the vax. That's amazing. It also says that winter is going to be nasty.

It's going to be like flu in that it isn't going anywhere. The difference is that if you have any health issues or you're old, delta is going to mess you up a lot worse. Flu has no mental issues and has no lasting outcomes (unless you die). Covid is different.

What I'm reading is that delta attacks faster, which means that our relatively slow testing and quarantine strategies are less likely to catch it before it spreads.
