What you need to know about the virus in China "2019 Novel Coronavirus (2019-nCoV)"

Not open for further replies.
Certain masks like N95 requires fit-test to confirm style and size to be effective. Leaky masks not tight fit don't work!

Do Not Waste just because they sound better. If your application requires such equipment, they should provide you a fit-test as well.
 
BTW, I have a mask and eye protector, to spray trees and other plants, for years.

In an open space, such as the street or stairs (elevator to avoid), no mask is necessary. They are only effective to avoid touching our face with our hands or if we are sick.

The problem is closed spaces with a lot of movement of people.
 
I trust you guys are all good people. Consider getting hold on extra equipment when you see some, and be ready to send out some of your reserve to the professionals and needy ones when shortage comes.

Pm in television just announced that the Italian industrial sector will be shut down but for few vital sectors.
 
I learned the value of population pyramids in visualizing population dynamics and the relative sizes of age groups in populations while studying ecology at U.C. Berkeley in the 1070s 1970s. Here is a superimposed pair of population pyramids from 2016 (Source - Wikipedia) They are for China and Italy, female only. Notice the much larger proportion of older women in Italy. The male half of the graphs on the left side of the pyramid is similar, but not shown to help when comparing the relative shape of the two pyramids.

Look at the relative lengths of the bars within each nation's graph, and not the actual population figures. Population pyramids show the relative sizes of each 5-year cohort with respect to each other - and Italy shows the classic profile of an aging population with fewer babies and children, while China seems to be heading back towards an having an expanding population. The actual numbers of people are not important for such comparisons.

Obviously, nations with aging populations pyramids that display a shrinking base and "fatter" middle-age and elderly section have a greater potential for a high COVID-19 mortality rate.

Taiwan is even off the chart...

Chart from Financial Times

As I noted a couple of days ago, the slope of the U.S. line is frightening - and the testing program is miserably behind there.
 
If you look at the latest numbers in wikipedia:
  • In Spain on March 19th 831 dead, on March 5th 282 infected persons: deathrate ~ 300% :eek:
  • In Italy on March 20th 4032 dead, on March 6th 4636 infected persons: deathrate > 100% :oops:
  • In Germany on March 21st 46 dead, on March 7th 795 infected persons: deathrate ~ 6%
Clearly the number of infected persons for Spain and Italy must be wrong by very large amount.
So this is a little different from what I was suggesting. The point is the cumulative numbers are incorrect. So the idea is to take the DAILY fatalities divided by DAILY new cases 12 days prior. Probably smoothing by 2 or 3 days would help.
 
Feels like we've had seven years of partying and now there is the possibility of seven years of plague. Instead of Moses we got you know who. It takes a while and purposeful observation and reflection to get you head to accept a big change or new situation.

To me it's the year of living dangerously, not that I'm trying to live dangerously. The general sense I get is that it will take a year or so to get this totally under control.

I turned 63 on March 12 and had plans to see a performer in a small venue. It was cancelled. We did go out to a half empty restaurant. Living in NY we are in near total lock-down, especially after Sunday. Grocery shopping will be the primary if infrequent trip. Otherwise it's walking the dogs. Actually I feel lucky. We're retired and in good health and have a reasonable food stockpile.:)

I had no idea that both Berkeley and you were that old! It must have been really weird to see all those pioneer prospectors invading your lands after nearly 800 years of peace and tranquility. ;)
 
Everybody including the Spanish authorities needs needs to STOP the panic and fear mongering and start doing what Korea and China have done and start massive testing and chloroquine based treatment and get this thing over with quickly

The French prof, one of the best infectiologists in the world, whose work came to the attention of the Trump administration through a Tucker Carlson interview of a Stanford professor, and I have mentioned early on in this thread, has been saying "coronavirus, game over" for three weeks. Even after that development, a couple of major medical French medical figures found it themselves to ridicule those findings on TV, whether because of incompetence, jealousy or plain stupidity, only God knows. But it's never too late.
 
relevance of hydroxychloroquine?

since the beginning of the pandemic we talk a lot here about the treatment (currently under test)
several countries France usa brazil have already built up stocks.

here I translate (as I can) the interview of professor raoult the instigator of this treatment to my regional newspaper.

""He won't budge. Despite the echo of political and medical mistrust regarding his clinical trial, the IHU boss is convinced of the relevance of hydroxychloroquine to treat patients with Covid-19. Despite the media psychosis and his daily death toll, he repeats: you are more likely to die from something other than the Chinese virus. Whereas yesterday evening the president of the Scientific Council Jean-François Delfraissy solemnly called for a massive screening strategy, Didier Raoult had recommended it and implemented it as soon as the first Wuhan returnees arrived. In the corridors of the IHU, one slips that in this health crisis, "he put his balls on the table". History will tell if the shocking Professor Raoult was right. Meet him.

627 deaths in one day and 40,000 cases of Covid-19 in Italy, this is no longer the "grippette" (little flu) you were talking about a few weeks ago ...
Prof. Didier Raoult: In all likelihood, you don't understand at first glance. All situations must be put into perspective. What infectious disease did all the press get excited about last year? Measles. In the end, there were 1,000 cases with one death and there was an announcement every day in the media. The world of information lives in a parallel world to mine, the world of observation. We have gone from exaggeration to disconnection. There are 2.6 million deaths from respiratory infections in the world every year, can you imagine that the 5,000, 10,000 or even 100,000 will change the statistics?

We're not talking about statistics, we're talking about human beings, entire confined populations...


Pr Didier Raoult: What else do you want to talk about? People die, yes. The greatest excess mortality in France in recent years was in 2017: 10,000 additional deaths in winter, we don't even know if it's the flu. 10,000 deaths is a lot. We'll see if we can kill 10,000, but I doubt it.

The statistical argument is therefore the only prism...

Pr Didier Raoult: In Marseille, we diagnosed 120 positive cases, there were two deaths over 87 years old. They also died last year. Out of 100 samples taken from people who have a respiratory infection, these are rather serious cases. When we test 20 viruses and 8 bacteria, there are 50% of which we don't know what they have, that's our great ignorance. For all the others, there are 19 seasonal viruses, which also kill. Endemic coronaviruses kill more here than in China. I'm constantly confronting the causes of death throughout the region with this kind of rising anxiety bellows. Right now we're more likely to die from something other than Covid-19. Old age, co-morbidities and late treatment are all factors in mortality. It may be unheard of, but that's the reality. The only thing I'm interested in are the datas, the raw data. The data will stay, the opinions will change... I'm not telling the future, but I'm not terrified of it at all.

How do you explain the situation in eastern France?

Pr Didier Raoult: I am a scientist, that's what is missing in this country; a large part of the political and administrative world reacts as you do (the media, editor's note). We must not react like that. The only data I am interested in is observational data, I have no opinion. Only the press talks about what's happening in the East, I don't have any data. For Italy, they said worse, I received an analysis, it's like elsewhere, it's people over 75 years old. The Japanese have made a very nice experimental model by confining older cruise passengers to the Diamond Princess. We saw that it was contagious; 700 people caught it. But despite a very fragile population, only 1% died. This is the observed reality. When there are 1,000 deaths in the east, I will say yes, it is serious.


You're always going against the flow of the speech...


Pr Didier Raoult: Just because there are a few people in Paris who think certain things doesn't mean I'm against the current. In my world, I'm a world star, I'm not against the tide at all. I do science, not politics. Infectious diseases, it's not very complicated, it's diagnosis and treatment. It's the B-A ba, if people don't know the B-A ba of infectious diseases or chloroquine, which is learned in the third year of medical school, I can't do anything about it. I'm not going to reeducate the people who are remaking the world on TV sets. I don't care what anybody else thinks. I'm not an outsider. I'm the one who's ahead of the curve. The real question is: how did this country come to be in such a state that one prefers to listen to people who don't know rather than those who do?

24 patients are being followed in the clinical trial, how many people have been treated since...



Prof. Didier Raoult: We've dealt with others, but I won't tell you how many. I will inform the ministry first.

After six days of treatment, the viral load of 75% of patients is negative, but are they cured?


Pr Didier Raoult: They are cured of the virus. But if you have lung lesions, they won't disappear in three days. We don't know for the moment either if, once cured, you can get sick again, this has not been described by the Chinese who are two months ahead of us.

What about the 25% that are still positive? Is their situation getting worse as they say around the 7th and 8th days?


Prof. Didier Raoult: We haven't had any aggravation in the cases treated, but we don't see people in serious states. For the moment, serious cases are those that are neither detected nor treated and that arrive with very serious respiratory insufficiency. They go directly to intensive care and they will die there. If we detect and treat people early, there is a much better chance of saving them than 48 hours before the terminal phase.

Your strategy since the beginning of the epidemic has been to mobilize the entire IHU to do mass screening, why hasn't this been a national strategy from the beginning?


Pr Didier Raoult: That's not my strategy, it's common sense. I don't know why it's not a national strategy, it's a political choice. I'm doing my duty, period. I do what I have to do, I play my part in a play. But I didn't invent the theatre, nor the text. I'm the only one with classical thinking about infectious diseases when everyone's losing their nerves...

What about the side effects of hydroxychloroquine treatment?


Prof. Didier Raoult: What they say about side effects is simply delusional. These are people who haven't opened a medical book in years. More than a billion people have attente them, people who suffer from lupus have been taking them for decades.... I'm very familiar with these drugs, I've treated 4,000 people with Plaquenil over the last 20 years. It's not me who's weird, it's the people who are ignorant. I'm not going to learn about the toxicity of this drug.


The government has announced expanded testing of hydroxychloroquine, but by teams independent of yours, why?



Prof. Didier Raoult: That's normal. Until 30 or 40 years ago, when we were faced with diseases that were poorly treated or not treated at all, we didn't give a damn about the methodology. The first guy who had a staphylococcal infection was given penicillin, he was cured and everyone was happy. As we became more and more competent, we had to do double-blind studies and then make data public so that there would be no cheaters, particularly because of the financial stakes. Today, we know from the Chinese that the average carry of the virus is 20 days. We have the means to measure the viral load; we can see that it is falling, so it is working. We didn't need a control group. I'm glad we're expanding the trials with drugs that work, I'm just a doctor. If you have doubts about my credibility, that's not my problem. There are people being treated all over the world, I don't feel any more responsible for the patients in Paris than I do in Korea. It's the smart ones who get the best care. I'm not trying to be arrogant. If people don't want to look at the numbers, there's nothing I can do about it. We've done 2/3 of the tests in France, we've set up a war machine. Afterwards, you can't make a donkey drink when it's not thirsty.

I do not understand why people can be so cool waiting for the fog's clear, "let's just wait and see, the fire is not gonna make it across the river", and like "it's okay to have one more deadlier "flu" to come in and have one more thing to worry about and one more shot to pay for every year", which is good luck there is no way to eradicate/contain anymore. One more "oh sh_t!" moments and one more thing for everyone to play dodge the rest of our lives, how fun is that!

Because if this is a large over-reaction, the damage to that reaction is very real. And there would be many other situations that are large enough or larger to require the same over-reaction. It would make modern life impossible. The consequences of that would be very real, and much worse than a disease that may not be that big of a deal relatively speaking.

Or to put it more bluntly, you don't make big policy decisions by using the logic that even a single life is infinitely precious because you'll bankrupt the system and not only not save that one life, you cause the loss of many, many, many more lives.

The whole system currently is "waiting on the tidal wave" coming our way. The incomplete testing was/is guaranteed to make any disease look this way. We can't prepare for these monstrous health tidal wave events that are mis-represented by poorly done testing and a lack of knowledge.

The Dr. in the interview is giving a balanced view as someone who works in that field. You seem to only pay attention to credible people sounding the alarm bell. There are several equally credible people who work in this area saying the reverse. I'm not an expert, and such opposed views aren't something I'm competent to judge. The whole media, gov't, public psychology is clearly in something of a cover my ass frenzy. Seen it before, been a part of it a few times, and decisions in those sitatutions almost never are rational or good.

An out in another field example. About 49 people on average are struck by lightning in the USA per year. On average that is also just about the same number as killed by assault rifles per year. We didn't hear about presidential candidates debating how they were going to stop electrical weather related violence if elected. Sometimes you do well to drop the emotional knee jerk reactions and look at facts without a fog.

It's because we've been there before, and there's really nothing more can be said than sounding the alarm. Not like I wanted to, but I cannot find a Doctor that would say otherwise in Hong Kong, or Taiwan, or China. This is how strong the consensus and cohesion are here in the area, and conclusion is empirical.

As we speaking figures are rising again, because people are coming back from overseas so more import cases, and folks start relaxing which brings potential social outbreak.

It is not over-reacting, it's just fast acting, playing way ahead of the disease for big safety margin.
 
when early and massive screening as in Korea has not been applied ...
it is necessary to be very very careful!
here in the west we have looked too far and with a sometimes sarcastic eye at what happened in china without learning any lessons.
moreover, in our very libertarian, carefree, undisciplined societies, it will be very difficult to make the covid move back and finally, the collateral (economic) damage will be harder than the virus itself.
Only nature will say thank you for this break.
 
And come on, just wear a mask when gather, we're all working with our masks on, how hard is that?
