Writes Yascha Mounk (in The Atlantic). He offers "three crucial facts" that show it's wrong to tell people to "stay calm." The right answer is: Change "our behavior in radical ways—right now."
1. The cases are increasing exponentially. For example: "Italy had 62 identified cases of COVID-19 on the 22nd of February. It had 888 cases by the 29th of February, and 4,636 by the 6th of March."
2. It's "deadlier than the flu, to which the honestly ill-informed and the wantonly irresponsible insist on comparing it." We can't calculate exactly how deadly, but "the news from Italy, another country with a highly developed medical system, has so far been shockingly bad... suggest[ing] a case fatality rate of 5 percent—significantly higher, not lower, than in China."
3. Only "extreme social distancing" has been effective. It worked in China. "This suggests that anyone in a position of power or authority, instead of downplaying the dangers of the coronavirus, should ask people to stay away from public places, cancel big gatherings, and restrict most forms of nonessential travel.... Do you head a sports team? Play your games in front of an empty stadium. Are you organizing a conference? Postpone it until the fall. Do you run a business? Tell your employees to work from home. Are you the principal of a school or the president of a university? Move classes online before your students get sick and infect their frail relatives. Are you running a presidential campaign? Cancel all rallies right now."
In my household, we have radically changed our behavior. There's something I'm letting go that I've looked forward to for almost a year. It was a chance-of-a-lifetime experience on the highest level, and I have significant sunk costs. But I'm being rational and not agonizing about it or bullshitting some special rules for me that could make it okay to go ahead and do my special thing. I know it's way harder for most other people to embrace a lifestyle of social distancing, but I think these personal excuses and justifications amount to nothing when you're talking about participating in the exponential spread of a disease that could kill millions.
Don't be part of the problem. Control yourself.

Mike, you'd better do some more research.
Not sure doing research falls into Big Boy Mike's wheelhouse. Acting like a retard on the internet - he's got that under control.
Matthew, I read that as the kid being fine only with the parent having suspicious symptoms. Kid as possible asymptomatic vector if parent ends up testing positive.
The author seems over the top there IMO. If your reading is right that parent is a monster sending their sick kid to infect everyone.

You already said this and my counterargument was that an N of one is not meaningful statistically. The data I showed you is a more reasonable comparison. This is basic statistics.
Wow ARM tell me more about that -3.12 exponent AS IT APPLIES to epidemiology, the subject on which we were debating. I’m fascinated!
And this is a trivial test to implement. Instead of golfing and tweeting, Trump should have been figuring out what went wrong.
I am trying to avoid ARM but he thinks the test is "trivial." No, ARM, it is not a pregnancy test.
It requires a PCR machine, which are not unlimited. Do you know what PCR is, ARM?

There are literally hundreds of thousands of PCR machines in the country. Every molecular biology lab will have half a dozen. Not a rare item. It's like saying you might need a centrifuge.
Then tell me about Sweden’s minimum wage laws again, ARM.

For future reference it is forever. But, I know, math is your thing, not English. Who could ever forget your classic proof "The smallest exponential equation is the power of 2".
You are correct that N 1 is not a valid point of analysis but it is inarguable that both countries started with a single case at more or less the same date and that Italy with its smaller population today has much much higher incidence of infections and death. Difficult to infer from that that Italy is doing a super job while we are not

Lefties become instant experts on all subjects on which they opine because "lefty" and "you're a Deplorable Science Hater".
That is why Inga is an expert on military strategy and tactics, ARM fully understands statistics, Whoopi Goldberg knows a great "Dr" to be Surgeon General because the woman in question, Jill Biden, is, in Whoopi's opinion a "great great doctor". And I mean a "great doctor".
It took about 17 seconds for someone to left Whoopi know that Jill Biden is not really a "Dr", but instead just an EdD.
There are literally hundreds of thousands of PCR machines...
Uh huh. And WHAT ABOUT exemplars for testing? You need three usually.
Michael: "Difficult to infer from that that Italy is doing a super job while we are not"
What moron is actually claiming Italy is doing a better job than the US?
Serious whataboutism!
Whatever you think of the ideological background of the Atlantic or the author, the National Review is offering much the same guidance: https://www.nationalreview.com/the-morning-jolt/yes-coronavirus-is-worse-than-the-flu/?utm_source=recirc-desktop&utm_medium=homepage&utm_campaign=river&utm_content=featured-content-trending&utm_term=first.
There is much that we don’t know about the virus. We do know that it can kill, especially the elderly, that it spreads very quickly, has a long incubation period and will lack an effective vaccine for another year. Another reality is that you can have it, infect someone else (or many others) and never know.
Personally, I am going to follow guidance from those who have the experience and expertise in pandemics. Caution seems reasonable to me. It sucks to miss planned events and gatherings but the potential for making things worse for others without even knowing, and my own desire to stay healthy, is not something that I can ignore. Why risk making things worse?
I don't think the PCR machine stage of testing is as easy as ARM thinks
Of course, he is the expert, second only to Ritmo.

What I actually said was they did a vastly better job testing. That still stands. I think we have yet to see if we do a better job containing the virus. Italians are not the easiest people to control. Americans are more pliant, less chaotic, based on my personal observations, not actual data, so that is to our advantage. Also North Italy is very densely populated, as noted in this thread by others, which is also to our advantage. These factors are separate from the health care system, which based on my own observations and international rankings is quite good.
Who could ever forget your classic proof "The smallest exponential equation is the power of 2".
Context boy. It’s all about context. IF I am wrong prove it. Show me what exponents are used in epidemiology. What procedure are you following? Any asshole can claim to be correct. I explained it well. Surely you can explain your position.
I don't think you guys understand where we are today. The only argument the lefties/dems/LLR's find persuasive is when you use "you know, the..uh...the...the thing" as the basis for your argument.
The lefty dems find that that line of "argument" very VERY persuasive. And compelling.
Mike (MJB Wolf) said...

The virus sequences have been available for some time, as evidenced by the fact that other countries have done hundreds of thousands of tests already. What will be your next ill-informed observation? I can't wait.
Pre-MBA I was an English major ARM and sad to report an award winning published author. So yes I am actually “known” for my English more than my short stint as a science and math teacher. When I wrote “power of 2” I also made very clear, to people with comprehension, that the field in question uses integers. Not every field is limited in their exponential opportunities but this field is. You’ve gone a long way to avoid resolving this so I’ll sign off. Need to be in NJ by midnight.
ARM: "What I actually said was they did a vastly better job testing."
It is true that the US lost several weeks due to the incredibly stupid obiden-bama decisions during their administration to shut down all other sources of test kits other than the one centralized, federal govt facility....that experienced a "glitch" and lost another week.
So yes, it's true that the Italians did not have to deal with moronic obiden-bama rules.
The good news is that has been corrected now based on changes ordered about 3 weeks ago and test kits are now being produced in multiple locations.
There were 600k test kits available as of last Sunday with an expected further 1.1M tests kits ready to go by the end of this week to be added to another 3M test kits available by the end of next week for a total of about 4.7M.
Availability after that won't be an issue.
I certainly hope that the Trump admin is right now reviewing EVERY CDC/pandemic decision and rule made by our lefty moron friends during the "let no crisis go to waste" obiden-bama administration and immediately changing it back to pre-obama status so that we don't have to learn the hard way the next time.
In much the same way that we now know just how much corruption was engaged in by Puerto Rican democrats during the Sep 2017 hurricane which led to such a vast 5 of our aid being stolen and placed in warehouses to be sold off on the black market after having to listen to 18 months of the dems whine and whine and whine about Trump admin incompetence in not getting them the aid.....which did arrive but was stolen and hidden by dems....
....unexpectedly.

ARM: "Three years to fix the problem. Three years. That dog won't hunt."
It was an obama-era pandemic rule discovered during the first pandemic of the Trump admin.
It is impossible to go thru every single department at all levels of the US govt to reverse every single stupid obiden-bama rule that was put in place over 8 years...particularly when all the holdovers are in those managerial positions.
I'm afraid we will continue to find many more obiden-bama rules land-mines as we move forward.
Very reminiscent of the Carter admin appointee/lifelong democrat holdover in the US govt that made the ruling that ketchup was a vegetable for the purposes of school lunch nutrition analysis that the media attacked Reagan over.
This scenario is legion within the federal govt which is why every republican President should always immediately fire every single democrat political appointee in sight upon taking office and immediately reviewing any and all department rule changes that occurred during the democrat administration.
Also, it's not a good idea for democrats to weaponize the federal govt and spy on their political opponents and then use the fed govt to attempt to frame those political opponents.
Over 7,700 people died in the U.S. yesterday. About 54,000 in the last week.
It is impossible to go thru every single department at all levels of the US govt to reverse every single stupid obiden-bama rule that was put in place over 8 years...particularly when all the holdovers are in those managerial positions.
Yes, there are thousands. Betsy DeVos is going through them one by one. That is only one department.
With ARM's "hundreds of thousands" of PCR machines. it should be a snap. Actually, testing, IMHO, is of secondary importance. It will give a denominator for mortality but will not do a lot for treatment. Ramping up Remdesivir and Chloroquine studies will help. Part of those studies is treatment of severe cases. If the drug is as effective as in the WA case, it should mean ICUs will not be the limiting factor, as it has been in Italy.
By the way, I have been in an Italian ICU. ARM, I'm sure knows more, though.
BTW, ARM is now asserting flatly that Trump has been in charge of everything for 3 years so its all on him.....but on good economic days its still "obama's economy"!

Trump didn't do squat, but there has only been a few thousand tested to date so whoever actually did something they didn't do much. I have not blamed Trump on this, because he is so obviously clueless. His people are the problem.
The death rate in the U.S. is over 0.8 percent.
The coronavirus death rate in South Korea is 0.6 percent.

Bearing in mind Hawking's remark about his publisher telling him that for each equation he put into his book "A Brief History of Time" he'd cut his readership in half, exponential growth (or decay) means the rate of change over time is proportional to how much there is. That is,
dx/dt = kx
This is called a differential equation, with x representing quantity, k the proportionality constant, and the thing on the left (called a derivative) the instantaneous rate of change of x with respect to time, t.
Separating variables we get
dx/x = k dt
and integrating each side (the integral sign looks like a lazy skinny 'S') gives
x(t) = x(0)e^kt
that is, the quantity at any given time, t, equals the initial quantity times e raised to the (kt) power, where e is the second most important constant in the universe (after pi), approximately equal to 2.71828...
Note that it is the time variable that is the exponent, in contrast to other kinds of growth.
https://en.wikipedia.org/wiki/Exponential_growth#Basic_formula
"Italy appeared well ahead of the curve when the coronavirus outbreak began to spread outside China.
After detecting three cases, including two Chinese tourists at the end of January, patients were isolated in a hospital in Rome. Contacts were traced, and the country became one of the world’s first to cut transport links with China.
as would become clear in February, the virus had been circulating unnoticed in northern Italy via other local chains of infection, in all probability since mid-January."
At least according to this, the infections in N. Italy probably predate by weeks the first US infection, although the same caution applies about undetected cases here as there. Italy has unusually extensive links with China compared to most western countries, having become something of an economic dependent. As a consequence, they have been unfortunate in that they have become the test case for western countries in assessing what does and doesn't work with this virus. You could reasonably expect other countries to perform better because of the early Italian example.

World wide pandemic. People afraid to leave home. Entire countries quarantined. Schools closing. Crowds banned.
Yet, some people find potential temporary short supply of toilet paper and soap worthy of concern..
They have Costco in California? Navy personal capable of locating one(google is your friend)?
Just kidding. I do not believe the Navy has a shortage of tp or soap. Why would they?
The CDC should be shaken up and dissolved over its dithering on the testing kits. Late last month the governor of California said there were 200 kits available for whole state, all 40 million or so residents. At the same time, American companies making not-yet-CDC-unapproved testing kits and sending them to European countries, which made use of them. Geez.
This virus is contagious, and we have no idea how many people have been infected. Until the whole thing dies down, the inept head of the WHO should have kept his mouth shut -- he said mortality was 3.4 percent. We have no idea even now what the damn denominator is.
The only good to come out of this will be the opportunity for clinicians, epidemiologists, research scientists and public health experts to examine the situation: How many strains, how they traveled (at least in those countries with TESTING), the effects of various treatments, the design of broad-scale coronavirus vaccines, and the planning for faster production of future tests and vaccines. It also would be nice if all the useless supernumeraries who've been screwing the national and international response to this mess were made to walk the plank.
This also matters locally because every major city in the US has bureaucrats bleating for more housing, more dense housing and more mass transit -- ie., more opportunities to spread contagion. In addition, every major city has an increasing number of denizens "experiencing homelessness," including some who passed around typhus and leprosy in LA last year and others who spread hepatitis A in San Diego the year before that.

Idiot, military members should not have to be spending their own money buying toilet paper and hand soap for work. That is part of the military budget. It’s worthy of concern in that if the military is running short of these items for the troops, things are glitching up fast and the military should probably the last to see such shortages. My daughter bought her own damn toilet paper and hand soap for her home, she shouldn’t have to be using her military pay to buy toilet paper and hand soap for work.

I engage the great general public every day at work. My co-workers and I have been specially careful, since the beginning of last week, at frequent hand-washing, sanitizing surfaces etc etc etc. Not a soul has brought up the current plague in conversation with me, not a one. Business is perhaps marginally slower than at this time last year, and the boss is beginning to wonder if he can attribute this to prudence, fear, or panic. I doubt it.
Mass and confession as usual but Holy Communion under the one species only with a consequent reduction in the number of EMHCs. And we've been discouraged from indulging in the Rite of Handshaking. In other words (so far as I'm concerned) an appreciable improvement above the norm. I suspect that the local 'Susans from the Parish Council' imagine that these dispositions are the Archbishop engaging in stealth manoeuvres against the reigning liturgical ethos.

I am a hospice chaplain. I cannot avoid public spaces, and I am routinely with sick and elderly people. Mostly we've talked about taking basic precautions like hand washing, which we all already do.
The level of collective fear over this new virus is unprecedented in my lifetime. The H1N1 pandemic killed about a half a million worldwide, including 12,000 in the US. But I don't remember this level of panic that I am seeing now.
Colleges are cancelling classes, or moving them online. For how long? Months, years? All sporting events are to be played in empty venues for the rest of the year? The whole thing seems amazing to me.

All true. However: (1) It is always a matter of interest whether one’s interlocutor is a person of intellectual honesty and sincerity, if for no other reason than that it is a waste of time and effort trying to use reason to persuade people who lack those qualities; and (2) for that reason, internet trolls seeking to engage interlocutors maintain finely tuned “whataboutism” detectors and readily level the charge as a counterattack against anyone who draws attention to their hypocrisy.
Michigan Governor Gretchen Whitmer today declared a state of emergency. There are 2 corona virus cases in the entire state. Both persons are hospitalized and receiving treatment. One traveled internationally, the other did not.
COVID-19 has killed 32 people in the United States since February 29.
So far this year, there have been 90 homicides in Chicago — 67.6% black, 86.5% male, 86.5% by gunshot.
(https://heyjackass.com/). Yet no one cares.
What a joke this mediamaniacal coronavirus panic is.
Still no fatalities under 50 years of age nationwide, yet schools are closed. Universities are telling their precious snowflakes to stay home.
International travel continues, yet Customs & Border Patrol have no protocols to evaluate entrants for disease symptoms. Including people from Italy, Korea, et al.
People are hollering bloody murder about the lack of test kits for a virus that is less than 2 months old in the United States. That is unserious.
60,000 people died from influenza last year. Some perspective is in order.
Most of the “exponential” infection numbers are happening in self-proclaimed Sanctuary Cities — which will not cooperate with federal authorities unless/until they need something. Then they whine the federal response is not fast enough. That’s very strange.
If we’re serious about this “catastrophe,” and are encouraging people to restrict non-essential travel, that begins with shutting down the border to non-U.S. citizens. Now.
If we’re not willing to face these realities and do these things, we’re just doing the Chicken Little dance on TV. Anxiety masturbation.
And if it’s “not that bad’ (yet), then shut the #$@% up. Grow a pair and care of your elderly family members and stop yelling for the federal government to “do something” yesterday. There are remedies in process.
“Control yourself”??? Look in the mirror. If you’ve gotta make some tough choices, make ‘em. Stop projecting your fears on the rest of us who have to work to pay your Medicare tab, for God’s sake!

Full crowd at Canucks game tonight.
"The epidemic tree with exponential growth dynamics was stochastically generated assuming a mean basic reproduction number of 1.5 in the absence of interventions or behavior changes."
Mean Basic Reproduction is R0; which is defined as this. I'm not sure if that is the exponent when one is using time to determine the amount of doubling. In fact, since R0 "is the number of secondary infections produced by a single typical infection in a rarefied
population, how do we define it when there are multiple types of infected individuals," then if you were writing up a formula, the exponent would be on the opposite side of the equals sign, I'd think. You'd have X^Y=R0 in a very, very basic exponential equation, right? If you have X sick people over Y time period, you get R0 sick people.
Are you absolutely sure that R0 is the exponent here?
(That quote is from Figure 2 from ARM's link, with follow up links based on the works cited from there.)
The original source also says: "The presence of early sub-exponential growth patterns have direct bearing on the definition, estimation and interpretation of the basic reproduction number R0, a key quantity for disease control [35]. R0 is a dimensionless quantity that captures the average number of secondary cases generated by a primary infectious individual in a completely susceptible population. If the case incidence curve follows an early exponential growth phase during the first few disease generations, R0 is expected to remain invariant during the first few disease generations in the absence of susceptible depletion, control interventions or reactive population behavior changes. That is, the effective reproduction number, Rt ≈ R0 during the early growth dynamics of an epidemic. Yet, empirical observations indicate that 1) the duration of most epidemics, particularly those of rapid dissemination such as influenza and childhood infectious diseases, typically only last for a few disease cycles, and 2) epidemics with an early sub-exponential growth phase are common [7]. In the context of sub-exponential growth dynamics, even with small deviations from the exponential growth assumption, the reproduction number is not invariant during the first few generations of disease transmission, but is a dynamic quantity that declines over time towards 1.0 [35]. In the context of the generalized-growth model [7], the actual profile of the effective reproduction number is shaped by the ‘deceleration of growth’ parameter, p [7]. This highlights the fact that R0 alone could provide limited information about the transmission potential of infectious disease [36-38]. Further theoretical work is needed to connect sub-exponential growth patterns into classic theoretical results of epidemic theory stemming from decades-old pioneering work including that of Ross [3] and Kermack and McKendrick [4]."
That again makes it sound like R0 is *not* the exponent, since the exponent would be part of what you need to figure out how many people are being infected. It appears this is saying that if you know R0, you can find out if the growth is exponential or not, but that it isn't a strong corrollary ("provides limited information"), not that R0 is the exponent. I may go read some more, but I think that this may not show what you think it shows. Not only that, but this is a mathematical model, so, I'm not sure how useful it is whe talking about the actual data comparisons, where the exponent is a defined unit of time.
As if on cue. The usual suspects run around screaming," We're all gonna die!" and then wrap themselves in toilet paper. Toilet paper is the talisman. It will stop the virus. They annointeth themselves with hand sanitizer. They restoreth the status quo. Surely the state will watch over us. Forever and ever. Amen.
