I wonder how much is Delta still sweeping through many states?
Very minimal delta. Omicron has uprooted it. I see about 2-5% delta currently.
Nationally, CDC expects new cases next week to be 99.5% Omicron, and 0.5% Delta.
One of my adult children got COVID a few weeks ago and based on his symptoms, it appears to have been Delta. However, it was a mild case. We're in New Hampshire, and I think New England is among the last states to still have some Delta hanging around.
Why do you wonder that? There are many variants. Do you wonder about them all, or just the Delta variant?
I wonder about the data definitions, the data collections and data analyses, given the enormous anomalies available to be seen in all the “official” sources.
