I don't know what strain I had, because it wasn't tested. But in August (I am in SW Florida), my COVID was extremely debilitating. Knocked me on my ass for two weeks. I should have gone to the hospital, but was afraid of the Remdesivir and ventilator death sentence. If that was Delta, it was severe.
“If that was Delta”
In August, in Florida, it was almost certainly Delta.
That is the rough stuff.
Delta was the prevailing strain in Florida in August — sounds like delta. You were lucky.
