I don't know a good national set of equivalent graphs, but in California the hospitalizations are tracking the case counts with some delay, as are the deaths (though those are even more delayed), so I highly doubt you're just seeing additional asymptomatic cases.

The curve of the ICU cases vs overall hospitalized cases is interesting - it's lower, so potentially that could be good news like we're better at treating it now, or bad news that capacity is already low enough (<%10 in some counties) that it's harder to get an ICU bed than it used to be.
