I see you can't even distinguish "infected" vs. "will get sick". It's nice of you to publicly show your inability to do careful reading.
We have no idea how many are actually infected. Those 2.2 million are the number that got sick enough to be tested and had a positive test. There are millions more that are too early in the infection cycle to show symptoms, and tens of millions that may never show symptoms.
As long as you are looking at average cases per day, instead of time to double, you won't understand the math. As long as you conflate positive texts with infections, you'll distort the numbers. I ran through what a exponential/logistic increase would look like before with you, and see no reason it would be worth the effort to repeat it.
I don't know how many will get sick, and even less how many will be tested.
