I'll be astounded if not! We simply don't test.
The ratio of who gets a test vs who should, likely worse than 1 in 10.
So given 220K cases reported ->
>2.2 million COVID cases in US already?
>4 million? Perhaps...
We ground our models in data - but when key data is just not accurate (i.e. case counts are not), the models can be off. Sometimes by a lot
This would suggest a lower infection mortality, higher population immunity, and would start to paint a clearer path how to get society back functioning.
The immune system is an incredible recording device and serological tests let us tap into those records to answer questions like "how many people have been infected"
If so ~11 million in US could have acquired #COVID19
