re: A COVID statistic I cannot find......

I had it summer of 2020, with it being like a mild sinus infection but couldn't taste or smell anything. I got those back about 3 weeks after my head cleared up.

I got it again in late August this year, and it was a little bit worse. I had a constant headache, the cough, and trouble breathing for a few days, but no fever or body aches. It was like trying to catch your breath after running, except it didn't take much exertion to make me feel winded. I got it from my fiancé, and she had pretty bad flu-like symptoms for a couple of weeks.

So, it can happen, at least with different strains. I'm assuming it was the delta the second time.
