This is a pleasant thought, but we can't even get most people to obey speed limits most days, even though it's far easier and we know it would save large numbers of lives.

He's proposing scanning when you enter a public space.

Public spaces generally comply with these types of things because of the fear of getting caught by random inspections and steep fines and penalties.

This assumes that "economic activity will restart". Humans won't participate in dangerous activities. They may test the waters e.g. by ggoing to gyms, but as soon as a single case is found they 'll be scared back into their homes. It will happen even more so as the disease spreads and people learn about the death of someone they know. This will happen regardless of how much testing.

If you 're doing contact tracing right, you should need to test very few people per million every day. If you need to do a lot of testing, you ve probably already lost and will be forced to shutdown again. The solution is probably the second: antivirals.

OTOH i wonder what's the effectiveness of optical-based methods to detect viral particles: https://phys.org/news/2006-11-laser-nanotechnology-rapidly-v...

No analogy is perfect, but people need context to understand fatality rates, and see what risk is acceptable. Society doesn't have a goal of 0% death rates. We all accept some risk of death as a cost of continued existence. New data is showing that the fatality rate from covid-19 is more like existing risk we were all previously exposed to in the course of our existence, and not like a second version of smallpox.

As you said, you gotta die of something. If the covid rate equals the regular rate, then the US death rate would effectively double if we simply did nothing. That’s assuming no second order effects like a shortage of medical care making things worse.

> If the covid rate equals the regular rate, then the US death rate would effectively double if we simply did nothing.

For one year (or however long it takes to reach herd immunity -- and if longer, then death rates wouldn't double but increase much less). Assuming recovery confers significantly long lasting immunity, which I agree is not a trivial assumption (and one we don't know yet how reasonable).

Definitely not trivial, but -- in context -- means a reduction of life expectancy by less than one year. The US already lags Japan by 6; there's a lot that can be done to improve it by a year, with costs much lower than those currently spent to avoid reducing it by a year.

Paul Romer, an economist at NYU, has been advocating for testing millions of people a day for a few weeks. He is co-author of a piece in The Atlantic, "Without More Tests, America Can’t Reopen", https://www.theatlantic.com/ideas/archive/2020/04/were-testi... Googling for "romer covid 19" should turn up a lot of news sources covering the notion of testing millions of people a day.

Yes, he is the best I've found. This proposal is still at least an order of magnitude more testing though :) (on the order of 100 million tests/day, not 1 million tests/day)

Romer has called for as much as 30 million tests a day, which I think was based on some simplistic modeling. I think he was targeting everyone in the US being tested every two weeks. I think the two approaches are similar: let's test lots of people all the time, however many X million tests a day that is, so that we can quickly isolate and treat them. People are spreading it before they know they have it, so let's just test everyone all the time and not wait until they have symptoms.

Not trying to show bravado or anything, just pointing out that I and probably others feel this way; I would fight tooth and nail against pervasive, mandatory "test and release" policies on humans (and the necessary concomitant growth of the surveillance state). The second-order social and political effects of such a policy would be disastrous - orders of magnitude worse, in the long run, than the population-level hea…

This position truly baffles me. I can understand people who have reservations about tracking everyone with phone apps to do more effective contact tracing. But objecting to widespread, low-cost testing for virus infection as an extension of the surveillance state? I don't even know how to argue against that because it simply doesn't make any sense to me. Right now the population is clamoring for more widespread and effective testing. Why would people rebel against it? You think people would prefer to remain locked down, or to sacrifice 0.5-1%^ of the population, than be regularly tested for infection? Why?

That's why I think testing at the door is the more straightforward way to start. We can reopen factories, office buildings, even shopping malls, but no one gets in without passing the screen.

But that just moves the compliance and logistics problem back one step. Who's doing this massive amount of testing? If it's the government, you'd need armies of workers spread out everywhere. If it's the owners of these buildings, who checks to ensure compliance? Imagine trying to enforce this on every non-residential building in, say, NYC. It would be practically impossible.

Now imagine going out shopping, you’re stopped at the door, and you test positive. What happens then? The government puts you in a car and sends you... back to your apartment? Sounds like a dystopian nightmare, to be honest.

PB, can you elaborate on which other possible answers you've found for fast, easy, and abundant tests?

I'm working with a team that has a test that detects proteins associated with covid. It works like a pregnancy test and does not need a special scanner. Would love to discuss further.

This isn't a unique idea. This is the mainstream view. Everyone knows we need more testing and that testing is the only way to effectively ease distancing rules. That was a pretty extensive writeup to say what we've been hearing from all rational information outlets for a month.

Everyone says "we need more testing", but there's actually very little discussion of how that testing would translate into lower transmission. I'm skeptical any program less aggressive than the one proposed here would get R0 < 1.

Exactly. More testing is good, but actually stopping pandemic will require orders of magnitude more testing, which in turn requires a different approach to testing because the current way we do testing can't scale.
