No accurate charts on how many have it. Not one. Many folks who are counted are over it.
You're right in the sense that this chart even underestimates how bad the problem really is. It's probably even worse.
The shadow argument that you, and those of your ilk have been making is that this virus has already gone thorough a large percentage of the population and was so mild most never knew they had it. That may be true. There is no compelling evidence for that, but we may find that once we get the anti-body test widely distributed.
If that is true, we should be approaching herd immunity. You better hope that is not the case. As you approach herd immunity, your new infection rate should approach zero. If
this is what herd immunity looks like, then we are in deep kimchi. Because that means
this is as good as it gets. Which means we can expect 1000 and soon 2000 deaths a day to be the norm for the foreseeable future.
