Richard Korzekwa comments on What will be the big-picture implications of the coronavirus, assuming it eventually infects >10% of the world?

Those predictions are based on 80% of cases being mild. My claim is that if 90% of cases are undiagnosed, then substantially less than 20% will be severe.

Then you wouldn’t expect close contacts to both have severe disease frequently. I think this has occurred too frequently.
