1. we already have more than 2 million and mostly like several times that who are or have been infected

as really no anti-body testing is underway and reliability sucks on the tests as well.

2. I agree

but even the numbers I posted should frighten people

3. Trump can't be bothered by that now. He has a Twitter war to fight.

6. THIS

is the truth

4. That We Know Of

I'm thinking we have to multiply by at least 4.
I'm finding it hard to believe, as virulent as CV is, that 3 or 4% mortality makes sense.
It's worse than a flu, but 30 or 40x?
So, given the number of deaths, also likely understated, my guesstimate is the infection rate is way higher.
But, we don't need more testing. It's overrated per PINO.

7. I never argue with the experts

10. Even if we multiply by 10, (20 million), less than 10% in USA have some immunity.

Long lived or short lived immunity, that's not enough of the "herd" to do much good on preventing a major surge in cases with full opening up.

What is the factor? A well designed sample could determine that, but that would of course require testing and a functional federal government.

11. Current Estimates Are...

...60% minimum but 70-80% is an order of magnitude better.
Saw a doc with Gupta on CNN last night or Wednesday night.
I'm quoting what he said, but I didn't catch the name. Or, if I did I'm forgetting.

[Pobeka]

12. Think we (you and I) are confusing the concepts.

By "factor" I meant what you have to multiply the total confirmed by to include untested infected individuals.

The 60% minimum you are talking about I believe is the % infected of the total population needed for herd immunity to be effective, given the R0 of the contagion.

The herd immunity effect on R0 is ideally straightforward, I'll explain it if you don't know, but I'll bet you do.

[ProfessorGAC]

14. I Wasn't Arguing Any Point

Just relaying what I heard on CNN.
I didn't mean to get into a technical debate.
Merely what the expert thought, as you said, the critical value for herd immunity.

5. In a way it's a good thing the more that are tested but the problem is not having

a policy in place when we find out someone is infected and how to deal with making sure it doesn't spread from there.

[malaise]

8. Yes

the absence of a policy makes this worse

[Hermit-The-Prog]

9. "You're infected. Go forth and multiply!" -- this seems to be the policy.

13. The isolation should be at hotels and resorts like in Wuhan China.
