Chicago been consistently at 5% or less positivity rate since the beginning of summer. Cook county been pretty much the lowest numbers in the state for some time. When you see Illinois increases it's coming from way south down state. Chicago earned their herd immunity with riots, and holiday parties, now the Mexican's are making sure to double down on their immunity with a 5 day long independence celebration
basically we just need to let this run it's course in the bread basket of America. Down there in the Tenn and Missouri area
you could draw a circle a couple hundred miles in diameter and have 75% of the "hot" counties in America that includes OK, MO, AK, TN, IN, IL. Throw in some of Iowa and that's a big chunk of it.
