The need for testing to reopen

Here in AL, many are arguing that we cannot consider reopening because there are not sufficient testing resources in place. I am not looking for an argument, but want to understand just what kind of testing they want and how it would be used. As I understand it there are 2 types of tests:

1. Antibody tests to see who might have been exposed. I understand why this is of scientific interest, but don't understand what it has to do with reopening. Even if you could do this test on everyone, and say it showed that 5% have the antibodies, what do we do with that info? How does it affect decisions on reopening?

2. Testing to see if someone is currently infected. I get why this is important for diagnostic purposes, but it is a single point in time test. I could do a negative test, and then contract the Covid before I even got the result back. Even if we could do massive testing like this, what is the utility? I guess I could wave a paper around showing that I tested negative on X date.

Can someone explain?

Don't trust me of course but take this in context. Texas has 29M+ residents. To date, we have tested 169K people. Total. Additionally, the White House chose WalMart and CVS to set up drive thru testing sites nationally and to date, there are only TWENTY such sites up and running in all 50 states.

IOW, testing isn't important my man. Numbers are only numbers when they're 'fantastic'.

Well that is kind of what I am asking. Should TX get 29mm tests done, and if so how long will that take? And what is the utility at this point?

Now at the front end of an outbreak I understand the idea of mass testing to isolate and contain. But we are way past that aren't we?

You don't need to test the entire population

Take regional and city samples to give you an estimate

Let's take birmingham for example

210k people. Give the antibody test to a couple thousand people and estimate based on the results of that sample.

I think some people want everywhere to have a rapid test before you go in.

Basically check everyone, takes 15 minutes, and verify you are not sick.

Well I can understand the utility of this. Does such a thing exist?

Won't be long from now before people just say "frick it" and go back to doing what they've always been doing

It’s like the difference between watching Law and Order guilty conviction and real life.

Some idiots expect life to be like tv, they can get some absurd ‘all clear’ like it’s perfectly safe. They’ll probably get ran over walking to the bus stop...different issue.

Yes like you said we simply need to get to a point to where if someone feels sick we test them and they stay away, distance themselves. I’m not sure what else you can realistically due without a military martial law.

The constitution gives us our freedom to live life not a stupid spit test.

So if someone is negative with no antibodies do they have to go get infected and then recover before they are allowed back in the game?

They don't know why they want more testing, it is just the latest talking point/moving of the goal posts to try and tank the economy and keep Trump from winning in November.

If I feel fine I'm not letting a stranger stick something up my nose or inject me with something. I dont get the flu shot either.

It exists, but universal testing for the disease is stupid, useless, inefficient, and impossible. At the US maximum capacity for production it would take years to produce enough tests just to test the entire population once. Let alone testing people every fricking day or two to see if they're sick yet.

It really pisses me off when people are fricking stupid enough to demand universal testing for the disease. Buddy, you need some more intelligent friends.

Antibody testing is the only way to go if you're going to do it, but are you seriously going to bar people from making a living just because they haven't had the disease yet?

The antibody test lets you know what percentage of the population should have some immunity. It lets public health officials decide how many new cases in a given amount of time is a risk for wider spreading and tailor responses better to avoid everyone hiding in their houses every time someone coughs. All things considered, the more immune people you have the harder it is for the virus to find new hosts and the more sick people you need at one time for there to be a risk of it exponentially spreading again. This does not have to test everyone. A statistically random sample will do.

The ongoing infection test is even simpler to understand. If you test positive for ongoing infection, then epidemiologists can begin contact tracing you to identify those likely to be exposed to get them to self-quarantine and head off the spread. This effort doesn't need to be 100% successful to help curtail the spread and the more and more herd immunity we have, the more room for error we have on this front.

I believe the capacity for widespread rapid testing they're talking about means more testing like you have for the flu, not testing everyone constantly. The idea is that you get sick and go to the doctor and know in five minutes if someone needs to be on an isolation protocol and drug regimen instead of knowing a week from now. In addition, you contact trace and give rapid tests to all of those people and follow up regularly with rapid tests for the following two weeks. You can get on top of tracing the spread quickly that way and not have the week delay in test results causing problems. The contagious prodrome period confounds things, but it's just not reasonable to test everyone constantly to try to identify people who might be infected and asymptomatic without any reason to expect they would be infected. It's also not reasonable to expect the people to tolerate that kind of invasiveness.

A five minute office test can work wonders in halting a chain of transmission. Strep's a good example. That shite spreads like a hooker's legs, but we don't test everyone to keep strep is in check. You have a sore throat and your doctor gives you a five minute swab in the office. You get a diagnosis, you get your medicine, and you stay away from other people until you're better. Just being able to know in five minutes and take effective action at that point will work wonders.

Rapid testing exists today, but nowhere near the quantity for every business to have it
