On the Diamond Princess, where most of the passengers were in their 60's and 70's and you would expect at least a 5% fatality rate, the actual rate when everyone was tested was 2% of those with symptoms, 1% of those who tested positive, and 0.2% of all the passengers.

A global lockdown doesn't just destroy the economy. It kills people. In some Caribbean islands, 80% the economy is tourism. Now, they suddenly have 80% unemployment and people can't eat. Every year, global GDP increases 2.5% and global life expectancy increases 0.2 years. A 3 month lockdown (what it took in China and Korea) means a 10 year setback, or a 2 year reduction in life expectancy. That is 116 million people killed through reduced income to pay for food, sanitation, and health care.

https://www.imperial.ac.uk/media/imperial-college/medicine/sph/ide/gida-fellowships/Imperial-College-COVID19-NPI-modelling-16-03-2020.pdf report suggests that COVID-19 epidemic in the US is only at the beginning.
But how do they know that without extensive testing for COVID-19?
Much more likely explanation is that the US is at about the worst part of COVID-19 epidemic already (or even beyond the worst part).
The reason why daily cases of COVID-19 rapidly go up -- is because the US makes more and more COVID-19 tests every day.
So the trend looks scary because number of detected COVID-19 cases rapidly goes up. But the number of real COVID-19 cases is already at the peak and is likely to go down in the following days. Most of these real cases of COVID-19 still stay undetected.
Meanwhile, the number of tested COVID-19 cases may still go up for couple of more weeks - until it hits the declining tail of real cases.

Donald Trump said today: "in the war against Chinese virus".

So Trump implies that the US is kind of in a war with China.

WTF?
Trump should have known that the problem is not the Coronavirus itself, but our society panic about it.
Bringing up that war reference and blaming Chinese for detecting Coronavirus - will make the panic situation worse, not better.

I think that Trump will lose the next presidential election (2020-11-03).

The coronavirus has been circulating undetected and has possibly infected scores of people over the past six weeks in Washington state

Up to 3,000 have died from COVID so far, mostly in Hubei. Hubei has a population of ~60 million, which is ~18% of the US population. About 60,000 people died from flu-related illness last year in the US. The same proportion in Hubei would be 10,800.

So it seems it is demonstrably less harmful than flu. Why China or the World is reacting the way is it will be a great question 3-6 months from now in retrospect.

US did not test patients for Coronavirus:

The guidelines for testing were so absurdly stringent because there was almost no testing capacity in the US, despite their being hundreds of labs with RTPCR equipment, because the CDC screwed up their test kits and the FDA used emergency powers to prohibit labs from developing their own tests, and forbids the creation of commercial test kits and the importation of foreign ones. Three weeks after CDC (after an already unconscionable delay) shipped the non working tests, they have "fixed" this situation by permitting labs to use the 2 of the 3 primers in the original test that mostly work. So as of yesterday we are starting to have the ability to actually test, and the criteria are being loosened.

They discharged me, said I don't have Corona virus, since they didn't test me for it

The buzzfeed article stated exactly what the faulty reagent is: the DNA primers are causing unreliable test results. Designing working dna primers is not by any means a difficult task for any half-competent wet lab biologist. That said, I'm unsure why the CDC had to design their own instead of using the primers being used in Hong Kong. There's gross incompetence all around and given that the CDC has been defunded for the last few years, the folks there are probably in chaos like a headless chicken.

Covid-19

Covid-19 reproduction strategy is to use kids as carriers by making sure that kids (and other people with a strong immune system) are not getting too sick when they are infected. That gives carriers plenty of time to spread Coronavirus to other people.

That suggests that Covid-19 is, actually, not as deadly as initial reports suggest. Most likely the number of infected people is heavily underreported.

If the number of people infected by Covid-19 is underreported 10x, and the number of people who died from Covid-19 is reported accurately, then Covid-19 mortality is overeported by 10x.

It is possible that Covid-19 mortality is comparable with mortality of a regular influenza (0.2%), but scientists inflated Covid-19 number to 2% by missing underreported infections.
