They would need a lot of those Abbott machines. Those tested in the past week wouldn't need another test. Not saying this is feasible but if they could pull it off it might encourage people with health concerns to fly again.

But if I test negative today, I could test positive next week. I’m in that higher risk group due to age, not so much health risks.

What prevents someone in the higher risk group, or even lower risk group, from demanding to be tested every week, week in and week out?

How do you get their mind to wrap around not needing to be tested every week, unless there is something that changes; exposure or symptoms? Or even worse, demanding it because of human emotions or political reasons? You know there will be some.

I think the real benefit and importance of testing is to find those who are positive, so that they can be quarantined along with contact tracing. It's like kissing millions of princes to find the Corona frogs, I guess..

This of course only makes sense if the testing is widespread and maybe even ongoing. A half-hearted approach will not work, you gotta go all in.

That's S. Korea's approach if I'm not mistaken.

walmart and Home Depot employees could make the same case.
