Pureblood.
Think I had it in January of 2020.
Suspect I had it again last June. (There’s a tale tell signature of this virus I’ve never had before where I get an initial bad fever that breaks but then for the next few days I get bouts of mild fever for a few hours)
First time I had a fever of 102 for about 4 days, it broke then I had a fever off an on for about another 5 day of 99.5 to 100.5 and then took another 5 days after THAT before I started feeling normal.
Last June I started feeling bad and got a fever of 101+ for about 24 hours then had the off and on fever for 2 days and was up and running about 2 days after that.
It’s a variant to be sure so there may not be perfect response but my 2nd attack was much less virulent. I’d say my body is working normally.
Probably the majority of the population have experienced the same.
My family of four has not been vaccinated. Last year my younger son came down with a nasty case of COVID. Within a few days we were all positive with COVID.
My younger son & my wife were hospitalized. She almost died.
My other son and I were asymptomatic. I had us both tested for antibodies about six months later so I’d know if we had really caught the virus. We were both chock full of COVID antibodies.
Did you get those shivering attacks before the fevers hit. The only other time I got rigors like that was when I had neutropenic fevers while being treated for AML.
I’m glad your 2nd case was easier. I pray there isn’t a 3rd
