Handshaking is a really weird thing to do.

Maybe we should change it to headshaking. BTW, when I spent some
time in south India in my youth, I was amazed to see that shaking
one's head meant 'yes', particularly when it's meant to convey
complete agreement. But I got used to it and sometimes found
myself doing the same thing.

Vertical shake is yes, horizontal is no.


The Indian 'namaste', though normally not used in my state, is a
good substitute for handshaking.

The japanese have been sanitary for thousands of years. They bow.



Yeah, just be sure to observe the proper horizontal offset...or BANG!

When I was in Japan, I instinctively bowed in response, but I'm sure I
did it wrong. The Japanese are really polite to us barbarians and cut
us a lot of slack.

I messed up the business card protocol too. But they bought our stuff.

Wuhan, an early victim of the pandemic, declines blame.
The virus, the perpetrator of the attack, doesn't understand the
concept of blame. The width of the world is not responsible, nor
resposive, to the blame.

Blaming the victim... is a cowardly attack.

What do you expect for a group of utter idiots who embraced a
wartime draft dodger who hates blacks, hispanics, wind generators,
Asbestos laws, mayonaise, proper pandemic response directives,
factual news and information, and consensual moral sex?

When they show up I retreat to my office and put on some comfy

I must remember that tip; thanks!

I'm swamped. I just finished the old JFET Idss / Vth dance designing
a uA current sink, cruising Digikey for parts. As usual, in the end
I gave up and switched (this time to a MOSFET).

It's a pity. Idss is 6:1, and Vth is 6:1. If they could tighten those
ranges up a bit, they'd sell a lot more JFETs.

The White House and congressional intelligence committees were briefed on the scope and threat of the coronavirus in January and February, but President Donald Trump has not stopped exports of key medical equipment – a move taken by at least 54 other countries so far.

The data show how U.S. manufacturers stepped up production and cleared out inventory to supply protective medical equipment to China for weeks, even as the threat of the coronavirus became clear.

Can we say rank incompetence?

Sorry, but Pres. Trump has invoked the Defense Production Act to halt this travesty. 3M is now onboard with the crisis.

Yeah, Trump straightened them out! He got them to do what they were doing already!!! Way to go Trump!

Oh, turns out Trump did not invoke the DPA to have 3M stop shipping to other countries in North America.

"The President did not explicitly order 3M to stop exporting under the DPA."

China didn't contain it, in the sense of stopping it getting out into the rest of world - but that did happen before had got a proper grasp of what was going on. They limited their total domestic infections to 82,758, while the US is at 792,759 and that number is still going up a nearly 30,000 per day.

Russia stuck you with Trump. That was evil of them.

China had the bad luck to get hit by the Covid-19 virus but they did tell everybody else what was going on when they finally realised what had hit them, which was good.

> TrumpRussia bad, BidenChina good? Something like that.

Where did Biden get into this? With any luck, he'll be your next president.

He's not exactly wonderful, but he's not Trump, which would be a big step forward.

Of course, with Trump in charge of the "stop Covid-19 campaign", there may not be enough people left in the US in November to make it worth holding an election, and both Trump and Biden are in the age group where Covid-19 is frequently fatal.

Sloman is entirely innocent of irony.

But we, fortunately, are not. Perhaps a different phrasing?

"China has done remarkably well containing the Wuhan Chinese virus
responsible for the current world-wide pandemic."

James Arthur is a master of spin. He's rather less interested in accuracy.

China eventually did remarkably well containing the domestic infections of Covid-19, bearing in mind that it first showed up in Wuhan and it took a while - roughly six weeks - before they properly understood what they were dealing with.

In an ideal world, the virus would have been contained before it got out of China, but it wasn't. Strangely some foreign countries failed to learn from the Chinese experience, and failed to contain their own outbreak anything like as effectively. The US is a particularly horrible example. Quite a few did manage to learn from China's experience and have had many fewer infections per million than the USA (which now stands at 2,395 with lots of the country left to infect). Australia is at 260 and New Zealand at 300, while South Korea - which started early - is at 208. Taiwan is at 18. China managed to limit it to 54, from a standing start.

They didn't know what had hit them, and disciplined the first doctors who tried to inform them.

> That's just obvious.

If you chose to understand "containing the virus" as stopping it getting away before you know it's there.

What's equally obvious is that when they had realised what they had to deal with, they dealt with it effectively, and told the rest of the world what was going on.

Some countries were in a position to act on the information - Taiwan limited their total infections to 18 per million people, which is better than China's 54.

South Korea did tolerably well, at 208. Australian (260) and New Zealand (300) seem to have got their act together now.

The USA with - 2395 and still rising - is one of the disaster areas which is doing remarkably badly.

Also noteworthy is that the Chinese Communist Party totally clamped
down on internal travel to and from Wuhan, but did not shut down the
airliners flying in and out to the rest of the world every day.
Ten thousand travelers a day, to the United States alone.

That's not blaming, that's fact.

That's politics. They were in a position to lock down their own population.

Stopping foreigners from going home wouldn't have played well.

In reality, the destinations were in a position to check incoming travellers for signs of infection and insist on a 14-day quarantine. That's their responsibility, not China's.

The US had it's fist recognised case in January, and clearly isolated them successfully. Their epidemic didn't get under way until mid-February, and because nobody had gone to the trouble of getting enough Covid-19 test kits out into the field, the first known case of community transmission had died before the test results had come back.

It wasn't a great performance.

Which probably reflects the fact that US testing is woeful. It could also suggest that the antibody test is producing more false positive than it should. Covid-19 is no the only corona virus around - one produces about 25% of common cold infections.

https://news.usc.edu/168987/antibody-testing-results-covid-19-infections-los-angeles-county/

It might, but probably doesn't.

On the worldometers.info site, 97% of current cases are classified 'mild,'
3% 'Serious or Critical.'

Which is unexpected. It's possible that the virus might be evolving a less lethal variant which lets it's victims stay active for longer and infect more people, which is the usual pattern, but Covid-19 is still killing a lot of people

If we assume all those 'Serious or Critical' 3% are doomed, and pick the

Well, no, it doesn't, unless we get more info.
First, the dample is of 863 people, 36 of whom seemed to have antibodies.
For a random sample, that means 36 +/- 6 if the test is perfect.
If the test were capable of 1% false positives and 1% false negatives, you'd have
to consider the '36' number to be +/- 10

That may be how they got the range they're using, but I don't know, and some very
minor uncertainties in randomness or in test veracity would change it. A single
study, while interesting, isn't completely conclusive.

If the sample is truly random, were there any active infections? Where do antibodies
show up, is this a blood-draw test?
