Let's assume this Santa Clara testing is true and 2.5% - 4% of the population has had the virus. (I'm skeptical, but that's another story.)

We need about 60% of the population infected for herd immunity.

That is a range of 15 - 24 times more cases than we have now to reach herd immunity.

Assuming 2.5% - 4% infected and our current 38000 deaths, if we were to reach 60%, that would be 570,000 - 912,000 deaths.

That's shocking to me. Did I do the math wrong? Someone check it.

I really don't think we should be in a rush to try to obtain herd immunity.
