For the moment I'd say that a herd immunity approach certainly wouldn't have resulted in less deaths and at this point the numbers would suggest (in hindsight) that the way to go was what they have done in Germany/S.Korea.

Some pretty decent biomedical statisticians disagree.

This is a new one. For me anyway. Anyone heard of viruses traveling on polution particles?

Especially in cooler climes...makes sense to me. Can you actually breath enough in to get it...or does it extend the cough radius so to speak.

They might be right over the long term.

Based on what we have now in terms of numbers the UK could either (in a best/worst case scenario where the lockdown has had no effect) be at where we are now on 299 deaths/M, likely to get up to where Spain and Italy are on about 450 deaths/M or we could be where Germany (70), Portugal (86 - with far less economic resources than we have in the UK) are at.

For the time being I know which position I'd rather we be in.

Ok that makes much more sense. I'm still not sure which careers have gone permanently so that people can't go back to them once the lockdown has lifted. In terms of the commitment in terms of training etc that would have put in to get going in their career I guess the big one would be airline pilots. Maybe chefs also? Finding it hard to think of other specific examples.

One of my college roommates also served as groomsman at my wedding. Good friend still. He worked for a very well known wafer fabrication design software company in silicon valley. 51 years old. Been with this company for 25 years. He and his entire team let go en masse last week. Since nobody is buying anything (including the largest companies in the world), they had no use for sales and service teams. They got a small severance package.

Ageism is rampant in silicon valley. An 'old timer' like him may be eventually replaced. But it won't be by a 51 year old. It'll be by a twenty-something from India most likely. The mature leavening he provided his teams won't be reproduced. He will look for something, but odds that he can get back to where he was are nil. So his career is effectively over in this industry. It's a hard pill to swallow, but it is what it is.

Maybe not:

Trump Halts New Green Cards, but Backs Off Broader Immigration Ban

After pledging on Twitter to end immigration during the pandemic, President Trump moved to block new green cards but stopped short of ending all work visas.
Mr. Trump said that his order would initially be in effect for 60 days, but that he might extend it “based on economic conditions at the time.”

“We can do that at a little bit different time if we want,” he said of a second executive order that could further restrict immigration.
.
.
.
“By pausing immigration, we will help put unemployed Americans first in line for jobs as America reopens. So important,” the president said. “It would be wrong and unjust for Americans laid off by the virus to be replaced with new immigrant labor flown in from abroad. We must first take care of the American worker.”

https://www.nytimes.com/2020/04/21/us/p ... n-ban.html

Apparently, the immigrant farm workers are NOT affected. Maybe not technical specialists either, such as engineers.

This should serve as a sombre reminder that the notion of "company loyalty" or "a company man" is not a mutually beneficial relationship.

This crisis should, I hope, have served as a wake-up call to the extent to which the bottom line trumps all other concerns.

https://www.stress.org/stanford-profess ... oronavirus

The full article is here https://www.statnews.com/2020/03/17/a-f ... able-data/.

I think it is worth pointing out that the date the article was written was 17th March - more than a month ago. A lot of water has passed under the bridge since then.

The original article is much more nuanced than the stress.org headline (and to a lesser extent the content of their article) suggests.

You can see the jump just by comparing the respective headlines:

Stanford Professor: Data Indicates We’re Severely Overreacting To Coronavirus

vs

A fiasco in the making? As the coronavirus pandemic takes hold, we are making decisions without reliable data

Emphasis my own

I think the original article is very interesting and definitely gives food for thought. For me the overarching message is that we don't have the data to know where we are at but if it turns out that they are closer to the Diamond Princess we will have massively over-reacted. The problem is that we don't have the benefit of hindsight to know how representative those results are compared to 'normal' populations and healthcare systems.

From my perspective if there is not enough data to know what to do either way long term - the best thing to do is to be cautious and reduce deaths in the short term till you have more data. Until of course economies start approaching a state of collapse and it is clear that there is no other option than to open things up and take whatever happens in terms of deaths on the chin. I don't think we are quite at that point yet - at least in the UK. Maybe the US economy is taking more of a pasting and needs to take that 'jump into the unknown' sooner rather than later.

Certain sectors of the system will have to open soon. The farm work needs to be done. The harvesting and processing of the produce needs to get done, corona virus or not. Yes, the grain can be done without as many workers, but not the fruits and vegetables.

Of course, the barley most definitely needs to get taken care of so the barley pop can be produced . . .

Detroit health care worker dies after being denied coronavirus test 4 times, daughter says
Corrothers said what bothers her most is that her mother was not treated well at the hospital where she worked for 31 years. She hopes that people do not get discouraged from seeking help the way her mother did after being turned away multiple times.
"If people feel symptoms, go to the doctor. You're the only person who knows how you feel," Corrothers said. "If you can't get treated at one hospital, go to another."
When she thinks of her mother, Corrothers said there is one thought that lingers: "This did not have to happen this way."

Since you found the article, and the other it links to interesting, perhaps you will enjoy a half hour interview of a biomedical statistician from a week or two back. It is a half hour long or so.

Just read the Belgian report guys:

It's all about the nursing homes. It's all about the nursing homes. Everything about the mortality is about the nursing homes. Everywhere.

https://www.stress.org/stanford-profess ... oronavirus

This has been linked and discussed previously. The difficulty with the premiss in this article is partly that it only uses a portion of his thoughts on the subject. This is the longer and more complete version.

https://www.statnews.com/2020/03/17/a-f ... able-data/

The original posting in Stat is actually from March 17, so even earlier. His prediction for US mortality is quite far off now.

If we assume that case fatality rate among individuals infected by SARS-CoV-2 is 0.3% in the general population — a mid-range guess from my Diamond Princess analysis — and that 1% of the U.S. population gets infected (about 3.3 million people), this would translate to about 10,000 deaths.

The general premiss is that we need more information about how the disease works, but he predicts and advocates based on this incomplete information to support his argument that lockdowns are not more costly than they are worth.

The closures are so difficult for all of us, and the economies, but to flatten the initial curve they have been essential, and now hopefully countries can open gradually along the lines of South Korea and keep more businesses going while increasing protection for more vulnerable people.

A few criticisms are also posted under the report.

This author fails to take that into consideration, as well as the contagion factor. Th fact that COVID19’s viral shed factor is 1,000 times greater than influenza, and it’s peak shed is during incubation when many times there are no symptoms (as opposed to influenza, which peaks after it settles into the lungs).

In the same article that you use the Diamond Princess cruise ship as a case study for fatality rates, you estimate that 1% of the U.S population might be infected. The Diamond Princess cruise ship saw nearly 25% of the ship’s passengers infected. Perhaps multiple your “lost in the noise” 10,000 influenza-like deaths by 20+.


“I’m sitting at home after my office closed today and still wondering why my country’s economy is being destroyed by panic.”

“…and the death rate will turn out to be about what the flu is. It seems most likely.”

If you want to know why then read more of the readers comments and you will see why. The contagion factor is excluded from the authors analysis, which makes his theory just as incomplete as the missing data he complains about.

For the time being I know which position I'd rather we be in.

I agree, mostly. It could be though that the lasting effect of the delay in mitigation measures in the UK could result in a greater portion of the population of working age and younger infected. If there are more 5-65 year-old people infected who had relatively mild cases, this would allow the economy to open more quickly and stay open more fully and consistently. I imagine also the bulk of the workforce is in the 20-50 range, which statistically have had more mild cases of Covid and thus probably more have been infected since many of those cases would have had longer asymptomatic periods.

I'm guessing by the mortality rates and the low testing in the UK that the newer studies showing that actual infection rates could be 50-85x higher than listed would put the UK closer to the 85x higher range. Germany's mortality rate would indicate they have been very successful in reducing the number of serious cases, but may also have reduced the number of total cases. That might make it harder going forward and into the autumn. Who knows, really? But many of their monitoring techniques for known cases should be adopted ASAP to reduce severity of individual cases.

147,377 x 50 = 7,418,850 (11.2% of the UK population)
147,377 x 85 = 12,527,045 (18.8% of the UK population)

Only about half of the UK population are working, about 33 million estimated for early 2020. Targeted serology tests of representative random populations by different age groups could be useful to help with opening strategies soon, if those tests can be made reliable.

There are several unknowns here, but there have already been studies showing that areas of density with high pollution in Europe especially showed higher rates of serious infections. Whether this is due to damage caused by the pollution in the lungs or from a more effective transmission through pollution particle transport is not understood.

The idea is that an aerosolised droplet containing virus could be 0.1-1 micron, while pollution particles can be 10 microns, so they function as tiny gliders for the droplet particles.

I'd guess that whatever the cases, the closer you are the more of it you're going to get, so getting one droplet at 100 meters transported by a pollution particle might not be enough to kickstart an infection. But maybe it is? Anyone?

A good piece. It is lacking though in statistical backup about how and when to open different locations. It's an opinion piece, and a justified one.

I am hoping things get opened everywhere sooner rather than later myself. The most important piece is really communication and effective measures for continuing the low transmission rates achieved by the lockdowns, or this will all have been in vain.
