The latent immunity notion isn't mine. I'm sure we all hope it's right in some way. I don't know that it is. Or, it's possible some of us have some "resistance" due to exposure of a similar CV. Imperfect resistance, perhaps at times sufficient to knock it down quickly so we have no symptoms.
I talked to a guy at the pool yesterday who has not been sick, but most of his office was, and he's been tested twice to have "raging antibodies", he said.
If you think Sweden's experience is entirely due to really good distancing and mask wearing there, OK, I think, maybe. I still say there is something we're all missing, the parts don't fit in my mind.
