Coronavirus, Meningitis Tell Us Without Borders We Die

Rome, deserted Spanish Steps during coronavirus lockdown



By Enza Ferreri


This article was published on Italy Travel Ideas


While all the attention is on Coronavirus, there is another illness that has been on the increase in Italy: meningitis, a disease of generally infectious origin.

Meningitis Risk from African Migration to Italy


Italian doctor Alessandro Meluzzi, while speaking on the topic of coronavirus, also said:
I want to remind everyone present of something that nobody remembers: the very strong growth of meningitis in Italy, especially in Tuscany, is related to the fact that the type C meningococcus [meningococcal type C bacterium], which almost did not exist in Italy, comes from the meningococcus belt. That is the Sahel, from which 90% of African migration to Italy originates.
He concluded by saying: “Let's try to tell that to the President of the Tuscany region. What I mean is that boundaries, like cell membranes, serve to survive.

"It is not a question of racism, this is not the problem, but that of stopping viruses and bacteria, otherwise we are delirious.

"Without borders we die. As cells need membranes and the immune system needs antibodies, borders are necessary for survival."

Meningitis Belt, in Africa Meningitis Belt, in Africa

Like Other Parts of the Natural World, We Are Not Interchangeable


Doctor Meluzzi is right.

The idea of a globalised, borderless world is a dystopian view, totally unrealistic and, if tried to put into practice - as many forces are trying at the moment, against people's will - it will lead to chaos and highly destructive consequences.

There is a reason why the various peoples, nations, ethnic groups have spontaneously formed and united themselves into separate societies.

Smaller polities are always easier to manage. This is why larger states are divided into federal states, then counties, provinces, regions and so on.

This is the way men naturally organise themselves, it is an organic process, not one dictated from above like the "one world" idea.

Nature doesn't exist just outside of us. It exists inside of us too.

We worry not to break the balance of non-human nature, what is generally known as the environment or the ecosystem.

But then, paradoxically or at least unreasonably, our culture's dominant ideology (although not shared by most people) holds that human beings are flexible and pliable to a fantastic point, for example holds that a person's sex can be chosen or changed.

Similarly, this powerful ideology maintains that the naturally-developed, organic human societies that have grown out of family and blood ties, together with a shared history, culture and, more importantly, religion, are not necessary and can be replaced by a global society with a world government.

In this view, humans are seen as pawns in a game of draughts or chess, which, being all the same, can move or be moved from one part of the world to another without any serious consequence.

A hypothesis that we are now experimenting on ourselves with disastrous effects.

Italy: How a Coronavirus Crisis Became a Disaster

Milan Duomo Cathedral Square deserted in coronavirus lockdown

By Enza Ferreri

This article was published on Italy Travel Ideas


Italy early in the coronavirus crisis was the first country in the world for number of Covid-19 cases, with its number of confirmed infections increasing very rapidly day by day, and the whole country was placed under lockdown, as is well known. It is important to understand what happened to provoke this exceptional crisis.

In a previous article we saw that, for fear of labels of racism, by not having quarantined all people coming from China, a measure recommended by the World Health Organisation and followed by many nations, the Centre-Left Italian government has opened the door to the epidemic.

Then we saw that the uncontrolled immigration that for a long time has particularly hit and shaken Italy among the countries of Europe, in addition to bringing security and crime risks posed by undocumented migrants' free circulation, has now turned into another possible dynamite waiting to explode: due to China-Africa close trade ties and the vast presence of Chinese in the continent, Africa can become an incubation venue and transmission channel for coronavirus, which means that lots of African immigrants to Italy may be carrying Coronavirus.

The migrants arriving in Italian ports may have the coronavirus without their knowledge - and without ours. And still without their knowledge they could contribute to spread it throughout Europe.

The consequences, in that case, would be potentially lethal given the absence of sanitary bulwarks in almost all African states.

The infection might spread to Europe through Africa perhaps via Italy.

African Countries at Risk


The director general of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, was very clear when he said that the "biggest concern", in addition to the epidemic itself, is that the virus may reach "countries with weaker health systems" least able to contain it, and the whole of Africa undoubtedly falls into that category.

Although, when news of the epidemic from China first started spreading, there were no confirmed cases of Coronavirus in Africa, there are now, and escalating fairly quickly.

Doctor Giovanni Rezza, specialised in hygiene and in infectious diseases, senior scientist at the Istituto Superiore di Sanita' (ISS) in Rome, and Director of the Department of Infectious, Parasitic and Immune-mediated Diseases, has confirmed that Africa could represent a problem: it is a very populous continent, he said, and has fragile and weak points in the health chain:
African states do not have the same network as European laboratories. And the various types of fever that people can get could be confused with other infections and not be recognised as Coronavirus. This is why international organisations should be on the alert.
Africa, except for a few specialised centres, does not even have the means to recognize this new virus.

Health authorities and researchers fear that the Coronavirus could circulate undetected in Africa, where less advanced health systems could quickly be overwhelmed by a local outbreak.

It's therefore necessary to close the Italian ports to migration.

Italy: Racism Fear Stops Coronavirus Vital Quarantine

Coronavirus mask worn in an airport


By Enza Ferreri

This article was published in Italy Travel Ideas

Italy has been one of the world's most affected countries for the number of infections caused by the novel coronavirus.

Walter Ricciardi, Italy's representative at the World Health Organization and Professor of Hygiene and Public Health at the Università Cattolica del Sacro Cuore in Rome, very clearly stated: "We [Italy] pay the consequences of not having immediately quarantined people who landed from China. We banned direct flights, a decision that has no scientific basis, and which did not allow us to trace the arrivals, because people were able to stop over and arrive from other places."

Professor Ricciardi was referring to the possibility left open to travellers of, for example, taking a flight from Beijing to Dubai, changing tickets and then heading to Rome or Milan.

Another authority on the subject, famous virologist Roberto Burioni, as early as 7 February was writing:

"The virus in China might be out of control, but it is not here yet. The only chance we have for not letting it in is only, and I repeat only, the quarantine of those who return. All, without distinction. It is not racism, but a simple and elementary measure of self-protection, which costs a little discomfort to the people who are isolated and provides us with infinite security, while avoiding hateful and unnecessary discrimination."

Dr Burioni later declared in an interview to Il Corriere della Sera:
Oh, I know, they called me an alarmist, even a fascist leghista [supporter of the centre-right Lega party], because from the beginning I claimed that isolating people from China was the only effective way to avoid the spread of the virus. I stress: people, not Chinese.
As you may have already noticed, the political climate in Italy has over time become excessively, paranoidly fixated against any supposed "fascism" or "racism", even when there is none, to the point of neglecting basic considerations of, as in this case, health and self-preservation.

Something similar happened in many other Western countries: see the example of the street distribution in Canada of bottles of hand sanitiser bearing the message 'Stop the Spread', referring not to Coronavirus but to xenophobia and intolerance. However, such attitudes of "the stigma is worse than the virus" in Italy have had more devastating consequences, due to the actions of the current government, which has been described as "the most unfit in the history of the Italian Republic".

On 31 January, the day after two Chinese tourists who had arrived from Wuhan to Milan Malpensa Airport were discovered as Italy's first two cases of the virus, the leader of the Lega party himself, Matteo Salvini, wrote on Twitter:

"Let me understand … The first two cases of Coronavirus in Italy apparently have quietly landed at Malpensa on 23 January and, without any control, travelled for days across half of Italy, until checking into a hotel in the centre of Rome.

"Is this how the government protects the health and safety of Italians? The Lega for days has been calling for quarantines, checks, blocks and information, but for Leftist politicians and journalists we were 'speculators' and jackals. Let us pray to God that there will be no disaster, but whoever has done wrong must pay."

He also tweeted: “Check every single entry. By sea, by air, by land. While other countries took immediate action, in Italy there was the impression that someone has been wasting time. And you can't play with the health of citizens."

Salvini's words, like Dr Burioni's, were welcomed by insults as well as totally ignored by the government.

Instead, a much more reasonable response came from a Chinese in self-isolation, married and mother-of-three Xia Weihong, 48: the Lega is right, she said to the Libero newspaper.

Italy's Centre-Left government was busy in fighting not an all-too-real virus but an imaginary risk of anti-Chinese racism, as if the highly-justified fear of contagion had been a symptom of dangerous xenophobia.

So we saw the President of the Republic Mattarella visiting a Rome's school attended by Chinese children to show his solidarity; initiatives like "embrace a Chinese" launched by Florence mayor Nardella; politicians and media people eating spring rolls in Chinese restaurants.

Except that, when a few cases of the virus were found in some parts of northern Italy, none of these personages went to embrace inhabitants of the Italian affected area.

Other posts on the subject will follow.

Debunking Debunkers: Global Disinformation Index (GDI)

Global Disinformation Index


A useful exercise is to debunk the debunkers. I've done it before with the UK's fact-checker Full Fact .

It's particularly important in this coronavirus climate of frantic "fact-checking" and "information-correcting".

An article recently published on the website of the AAAS (American Association for the Advancement of Science) is about a physicist, Danny Rogers, who has co-founded and is Chief Technical Officer of the Global Disinformation Index, with the noble purpose of saving the internet from lies, errors, fake news and what have you.

The first disinformation service he should perform is against some of his own claims during the interview, for example: "QAnon has led to people’s deaths."

This is a wide and sweeping generalisation with no basis in reality. If it refers, as the only tenuous link, to the murder of alleged mob boss Frank Cali by Anthony Comello in March 2019, it is highly flimsy.

Apparently on the advice of his lawyer Robert Gottlieb, Comello pleaded not guilty, since Gottlieb is trying to defend his client as not guilty due to mental defect.

According to documents obtained by the New York Times, Comello wanted to perform a citizen’s arrest on Cali to help Trump, as he believed the Gambino crime family's presumed boss was part of the deep state and that he "was enjoying the protection of President Trump himself" to place Cali under citizen's arrest. When Cali didn’t comply, the documents say, Comello killed him out of fear that Cali would kill him.

What is unclear, among many things, is why Comello thought Cali belonged to the deep state.

The connection of this murder with QAnon, what Leftists call a "conspiracy theory" that Trump and his presidency have been under attack by the deep state, is at the very least dubious.

On the same grounds we could blame any political movement, in most cases with better reason, of "leading to people’s deaths". Many examples come to mind, for instance the 14 June 2017 shooting At Alexandria, Virginia, Congressional Republican Baseball Practice which only for the presence of a security detail by a miracle didn't kill anyone but could have been a massacre,

James T. Hodgkinson opened fire on GOP lawmakers and staffers with a rifle as they prepared for the annual summer baseball game between Republicans and Democrats, wounding several people.

Hodgkinson’s social media profile revealed he was a Left-wing Bernie Sanders supporter who believed President Trump was a “traitor.” In one Facebook post of 3 months before Hodgkinson wrote: “It’s Time to Destroy Trump & Co.”

The AAAS article goes on to say:
GDI’s [the above-mentioned Global Disinformation Index] system analyzes content and context flags which can help assess any domain’s risk of disinformation. It rates the disinformation risk for websites based upon variables that include overall credibility, whether they push sensationalism, whether they contain hate speech, and whether the company embraces sound policies regarding content.
Now, since the article is published by the American Association for the Advancement of Science and the "debunking" website with a high-sounding name it analyses is co-founded and headed by a physicist, we would expect some more precision in its chosen criteria than this. What objective characteristics does "overall credibility" entail?

And, even more importantly, how do you define "hate speech"? What does this concept mean? What role can it have in a science-led effort of exposing disinformation?

It's an impossible task to give "hate speech" a role in refuting falsehoods, for many reasons. First of all, hate is a sentiment, an emotion, a passion. As such, it's in the realm of the subjective, not the objective. What you consider hate another may consider simply justice, or telling the truth. There's no objective yardstick for definition, let alone measurement.

Furthermore, "hate" has been overused ad nauseam by the political and cultural Left to stigmatise, place beyond the pale and therefore silence (or at least the Left hopes) its adversaries.

So, this other "fact-checking" enterprise on the face of it seems to be, like so many of the same kind, Leftist propaganda masquerading as a quest for the truth.

Negative Oil Prices, End of Environmentalists' Peak Oil Theory

Oil tanker

People who read my article Italy Coronavirus Lockdown, No Cars, Pollution Up were surprised to find out that, in the absence of car traffic during the pandemic lockdown, the air pollution all over Italy increased rather than decreasing as expected according to the current views.

But contra facta non valent argumenta, as the Latin expression goes, there are no valid arguments against facts. Perhaps the pet, fashionable ecologist theories consider only some causal factors and not others, they overestimate human activity to the detriment of natural phenomena, they focus too much on cars and industries and too little on the weather.

Indeed we should consider another case in which a theory long supported by the fans of Malthus has been debunked for the umpteenth time amid - but not because of - the coronavirus crisis.

Now, for the first time in history, oil prices have become negative. That means that oil producers and traders are paying market players to take oil off their hands. They got stuck between a gigantic oversupply of oil and an absence of places to store it.

The BBC blames it on coronavirus, but while the lockdown may have been a contributing factor, this historic low is not just the effect of the Covid-19 pandemic, as the oil price has been going down for years.

As Capital says,
it may prove to be the case that the coronavirus crisis accelerated and deepened a recession that was due anyway after a prolonged upswing.

...Finally, for all the talk of renewables and of carbon fuels being “stranded assets” that cannot be used, it is widely accepted that oil will remain one of the highest value cards in the energy deck, alongside gas and nuclear power.
A Colorado paper alerts: "Oil price: futures markets warn it won't recover after coronavirus".

You may have heard of the peak oil theory. It was one of the environmentalists' many neo-Malthusian ideas holding that, due to the fact that the earth's resources are finite, we'll get to the point that oil, after a "peak" of production, will become scarce and oil price will skyrocket.

In fact oil prices have gone down over time, and now they have even become negative. Peak oil theory has been repeatedly refuted again and again. But how could environmentalists, who supported a false theory, ever predict that? They foresaw exactly the opposite of what has happened. Similarly, those ecologist theories have turned out to be fallacious or at least doubtful about cars being the only or main cause of air pollution. This is what evidence and data show. Do we prefer fantasies instead?

Julian Lee on Bloomberg, declaring that the current crisis of negative oil prices is not an anomaly, has got closer to the explanatory cause much more accurately than those who blame the coronavirus lockdown:
If oil producers don’t cut supply, negative prices will come back to force them.

Crude oil's collapse into negative prices on Monday was a clear warning of just how scarce storage space for oil is getting. Prices below zero are the market's way of telling producers to stop pumping, now.

...with the world awash in oil, there was nowhere for them to store it. So they had to get rid of that obligation, at almost any price.
The situation has arisen because there is still simply too much crude being produced in a world that can’t use it.
The problem seems to be that oil producers are not cutting supply quickly and aggressively enough.

Compare this reality with the fiction of the greens' theory of peak oil that describes an enormous demand of oil confronting a very low and ever-decreasing supply.

What happened? Fracking happened, and electric cars. It's man's ingenuity and human choice, not geology, that governs.

This is what occurs when a theory, whether it is cars as a major responsible for air pollution or it is peak oil, is put to the test: this is the scientific method. Otherwise, it's pure ideology with no foundation.

Italy Coronavirus Lockdown, No Cars, Pollution Up

Rome, Italy, Coronavirus lockdown - deserted street

By Enza Ferreri

This article was published on Italy Travel Ideas


It’s so fashionable and radical-chic to blame man, what he creates and what he produces for any environmental disaster, real or imagined, these days. Pollution and anthropogenic climate change spring to mind.

During the coronavirus lockdown, which in Italy has strongly reduced car traffic in cities and country, these theories of how our air is affected by motor-caused pollution can be put to test.

And surprise, shock, maybe horror! It’s not what we thought.

Italy’s ARPA, Regional Agency for Environmental Protection, with control units located all over Italy monitors in real time the quality of the atmosphere and publishes the findings daily.

An almost incredible picture has emerged. In the overwhelming majority of Italian cities, the air quality deteriorated after ten days of "zero traffic" due to the lockdown imposed by the government resulting in an absolute lack of cars and reflected in images of deserted cities like in a post-nuclear bombing era seen in movies.

A world without one car, a test that could never have been carried out without an exceptional event such as the Covid-19 pandemic. Everywhere there is more or less the same picture, from Turin to Naples, going through Milan and Rome. All the pollutants under control by ARPA have not decreased, even during long periods without traffic. If anything, the pollutants have gone up.

Rome: Traffic Zero, Particulate Matter Up


Let’s start from Rome, certainly a unique city due to its perennial history of civilisation always, like the Arab Phoenix from its ashes, being born again, not to mention its immense heritage of architecture and art masterpieces.

The atmosphere is full of microscopic particles of solid or liquid matter suspended in the air called particulate matter (PM), which is a very insidious and dangerous pollutant due to its nano-dimensions. The level of PM is considered an important indicator of air pollution.

It was known that all these fine particles in the air are not caused only by human activity but are of natural origin. But the constant drumbeat of environmentalism has led to an overestimation of their human cause.

In the Eternal City, particulates, nitrogen dioxide and ozone in the last few days have had values significantly higher than those of the previous week. With cars completely eliminated, showing that much pollution is not due to car traffic. If vehicles stop circulating, the situation does not improve.

It was not possible to organise a total block of traffic for several weeks to really see what would have happened. Now the coronavirus pandemic has brought to a halt all activities, creating a gigantic open-air laboratory. A joy for scientists and researchers to get an unrepeatable scenario to analyse.

In Rome, a week after the total lockdown ordered by Prime Minister Giuseppe Conte, the amount of fine dust in the air had increased.

After an accurate study of Rome district by district dated April 16 and covering more than a month in full lockdown, the Lazio Region section of ARPA published a 44-page report from which the experts’ embarrassment emerges. They couldn’t imagine this result: particulates don’t seem to care at all about what man does, they carry on regardless.

PM 10 is higher in March 2020 in every corner of the city than in March 2016 (the year most similar to 2020 from a meteorological point of view). In some recent days it has been almost double that of previous years.

The last four lines of the 44-page dossier, full of tables, are: «The particular situation generated by Covid-19 represents an event that has never occurred before, which will allow to deepen the study of air quality and will provide useful elements for the evaluation of the short and medium term measures that are adopted by the various authorities for the reduction of pollution ".

The hint is: if this is the reality, many things must be reviewed.

Milan and Po Valley: Data Deny the Anti-Pollution Effect of Lockdown


Milan, capital of the Lombardy Region, Italy's second city and industrial capital, has never been so car-free and yet the pollution level of its air has not changed.

The large amount of particulate matter (especially PM10) is due to the arrival of strong winds from the east, experts write. These are large-scale air masses from the Caspian Sea region that have brought great quantities of fine dust. Once they reached Italy they dispersed, while inside the Po Valley they were trapped by the Alpine and Apennine arches.

The reduction of air pollution that had been previously observed through photographs from the space in the Po Valley had deluded us: they had not detected the effect of the antiviral lockdown resulting in fewer cars and industrial activities but the effect of the wind from Central Europe while it was sweeping the smog away from the Po air.

Instead, before the lockdown started there was a clear and uncluttered atmosphere, the transparency of the air which the satellites photographed and we attributed to the effect of the anti-contagion restrictions.

What about the satellite images that convinced us of the best air quality in the days of the infection? They were photographs from space that had captured not the effects of the lockdown, since many satellite surveys had been taken in the days before the traffic stopped, but the effects of the weather.

The prime factor that thickens or disperses the polluting emissions of Northern Italy - of artificial or natural origin - is the weather. The wind and rain clean the air more than the confinement against the virus, or they bring the polluting dust of the deserts of Central Asia into the lungs of Lombardy, Piedmont, Emilia, Romagna and Veneto, as happened in the weekend of March 30 and 31 when from Venice to Turin, from Bologna to Varese, without the movement of a car, the air of the North was plagued beyond all limits.

All this this was revealed by a study by Arpa Lombardia, supported by data from the other regional agencies of Northern Italy, whose detection units measured increases in smog after the closure of activities, industries and road traffic imposed by health concerns. On Saturday 30 March, with the contribution of desert sands, the dust in Milan was 84.4 micrograms, in Venice 152, in Verona 125, in Bologna 98 micrograms of PM10 per cubic metre of air. The European air quality target indicates the limit of 50 micrograms, a limit exceeded generously everywhere in Northern Italy.

Nothing, therefore, suggests that the lockdown drastically helped the region.

The specificity of the Po Valley is confirmed once again. As a writer put it: “Milan is polluted for other reasons: because it is at the bottom of a windless basin called the Po Valley".

A Gigantic Open-Air Laboratory


Starting from 23 February, the progressive adoption of measures to contain the contagion from coronavirus has determined a uniquely faster alteration in human activities than in ordinary conditions.

This has allowed scientists to measure in reality the consequences of some measures aimed at improving air quality, and more crucially to test many theories and assumptions about what gives rise to air pollution that had been long accepted but not properly tested.

When the first results were known, the surprise and amazement of researchers was evident. How is it possible? Someone thought of an error: if cars stop, pollution can’t go up. But this mistaken, as it turned out, prediction was based on a wrong presumption on the main cause of pollution.

This is how science proceeds: if a proposition describing a future observable event is logically deduced from a hypothesis, and if the event predicted occurs, the hypothesis is confirmed, if not it is refuted (or debunked, as the neologism goes).

The scientists’ conclusions: "In fact, it has been observed that the drastic reductions of some sources [like road traffic, Editor's note] have not always prevented the limits from being exceeded, even though they contribute to reducing their size. This clearly highlights the complexity of the phenomena related to the formation, transport and accumulation of atmospheric particulates and the consequent difficulty of drastically reducing the values present in the atmosphere in ordinary situations".

In short: reducing pollutants in the atmosphere is not always possible, as it is influenced by a series of factors not always under human control, like weather influences.

Is It Worth It?


Environmentalist lobbies have a great power in our times over political decisions and media coverage influencing public opinion. But, before blaming cars for levels of pollution for which they are not responsible, think of this: due to the coronavirus pandemic and the fall in demand deriving from it, 14 million European workers risk losing their jobs, as explained by Eric-Mark Huitema, general manager of Acea, the association of European car manufacturers, who defines the coronavirus emergency as "the worst crisis ever" for its impact on the automotive industry.

Italy Covid-19 Possible Breakthrough, Heparin Drug

The Monna Lisa with Coronavirus Mask

By Enza Ferreri

This article was published on Italy Travel Ideas


The mistake pretty much everywhere has been treating seriously-ill Covid-19 patients with ventilators, which requires a highly-invasive surgery for intubation, the insertion of a tube attached to artificial ventilation into the trachea, and didn’t achieve a good rate of success.

The hypothesis has now started to make headway that the main cause of death is not pneumonia, but a generalised venous thromboembolism.

Embolism is the obstruction of an artery or vein caused by a body foreign to normal blood flow, the most common of which is blood coagulation, i.e. clotting, in which case it is known as thromboembolism. The most frequent venous embolisms are pulmonary embolisms, in which a deep vein thrombosis gives rise to a thrombus, a blood clot, a part of which detaches and is transported by the bloodstream to obstruct a pulmonary artery, causing embolism.

Pulmonary embolism symptoms include breathing difficulties, and can even lead to death.

Treatment usually is by the administration of anticoagulant drugs, such as heparin and coumadin.

"Thrombosis Possible First Cause of Coronavirus Deaths"


Those above are the words of Dr Giampaolo Palma, expert in Echocardiography and Interventional Cardiology, who also said:
Gentlemen, Covid-19 first of all damages the vessels, the cardiovascular system, and only then does it reach the lungs. It is venous microthrombosis, not pneumonia that determines fatality.
He is one of the many Italian physicians who are using the anticoagulant medication heparin and exchanging information about it through a wide nationwide network.

One of the first was Professor Sandro Giannini of Bologna, who states:
Ventilation of the lung where the blood does not reach would be useless therapy; in other words, the cause of the lung damage is the development of a coagulopathy, disseminated intravascular coagulation.
This was discovered through autopsies and echocardiograms, following the disconcerting results of analysis of large samples of ventilated COVID-19 patients, which showed that mortality rates among them could be as high as two thirds.

The UK's Intensive Care National Audit and Research Center (ICNARC) published data of a study on the first 24 hours of 3,883 patients with confirmed COVID-19 (the illness from SARS-CoV-2) admitted to intensive care units (ICUs).
Among patients whose ICU outcome is known, 66.3% of the 1053 patients who required mechanical ventilated died, compared with 19.4% of the 444 patients who required basic respiratory support.
This mortality rate is much higher than for ventilated patients with different types of viral pneumonia, which is 35.1%.

These results are similar in the observation of smaller samples of patients in China and the USA.

Something was obviously wrong, and there have been recent claims of excessive use of ventilators and even risks of ventilator-induced lung injury.

Autopsies on patients who were ill from SARS-CoV-2 revealed signs of massive thrombosis.

In addition, from echocardiograms performed in Italy for Coronavirus patients it seemed that patients go to resuscitation for generalised venous thromboembolism, especially pulmonary.

The echocardiogram (or echo) is a type of ultrasound scan to look at the heart and neighbouring blood vessels.

In Lombardy, the region most affected by the novel coronavirus in Italy and one of the most hit in the world, cardiologists became convinced that a new approach was needed. The frontline Lombardy doctors announced:
The main problem is not so much the virus as the immune reaction that destroys the cells which the virus enters. Rheumatoid arthritis patients have never been hospitalised in our COVID-19 wards because they are under cortisone or an anti-inflammatory therapy. It has not been easy to understand this because the signs of microembolism are tenuous even through echocardiogram. By taking care of the infection at home, we could avoid not only hospitalisation but also the thrombotic risk. We have thus been able to ascertain that the most exposed hospitals are administering low-molecular-weight heparin (LMWH) to their patients, with good results.
The drug allows you to maintain the right fluidity of the blood, limiting the possibility of coagulation.

The Italian Medicines Agency (AIFA) has already launched an efficacy study on the administration of heparin, recommending a case-by-case evaluation for the time being.

At the moment, some data confirm its effectiveness, because anticoagulants are proving able to reduce at least by 25% hospitalisations in Covid-19 wards in Tuscany.

In addition, enoxaparin sodium, another anticoagulant medication used to treat and prevent deep vein thrombosis and pulmonary embolism, seems to have a double effect: not only it prevents thrombus formation but also it makes the SARS-CoV-2 bind with the drug thus preventing the virus from entering our cells and reproducing.

I'll keep you posted.


All emphases are added.

Coronavirus Lockdown Effectiveness, Other Doubts



One of the few certainties about this novel virus and the pandemic it is spreading is that, being new (or at least new to us, namely newly discovered), we don't know very much about it, and we are constantly learning about it all the time.

But, being human and not liking uncertainty in a similar way in which nature abhors vacuum, we try to jump to conclusions, any conclusion, in fact, just to avoid doubt, chaos and disorder (a very natural feeling). So we grab at many different explanatory theories, whether supported a lot, a little or not at all.

This is The Times of Israel reporting on the theory held by someone the newspaper describes as a top Israeli mathematician:
"I have no explanation but the numbers speak for themselves."

Top Israeli prof claims simple stats show virus plays itself out after 70 days.

Isaac Ben-Israel, who is not a medical expert, says analysis worldwide shows new cases peaking after about 40 days, slams economic closures; leading doctor dismisses his claims.
So, according to Professor Ben-Israel, head of the Security Studies program in Tel Aviv University and the chairman of the National Council for Research and Development, "simple statistical analysis demonstrates that the spread of COVID-19 peaks after about 40 days and declines to almost zero after 70 days — no matter where it strikes, and no matter what measures governments impose to try to thwart it."

What is intriguing is that, minus the mathematical and statistical calculations, a similar view, at least in its practical conclusions, is supported by another person in the news, who has been accused of "anti-Semitism", ie David Icke:
On Wednesday night Icke shared his unsubstantiated views in an edited interview for London Real: COVID-19, and shared baseless claims on coronavirus including that mandatory vaccination for the virus would be 'fascism' and include 'nanotechnology microchips'.

… he appeared to justify attacks on 5G masts around the UK, adding 'human life as we know it is over' if the construction continued.

The 5G theory has been discredited by experts, with Public Health England stating that 'the overall exposure is expected to remain low relative to guidelines and, as such, there should be no consequences for public health.' The new coronavirus is also spreading in places without 5G networks, including in Iran.
Strange bedfellows as they may be, Icke shares with Professor Ben-Israel the hypothesis that the lockdown doesn't help to limit the spread of Covid-19, as shown on this tweet of his with a diagram comparing countries with and without lockdown measures:

Covid-19-Lockdown Countries Compared

Compare this image, though, with the one pictured above this post and you'll see how focusing only on deaths per million and removing cases per million gives a very different picture: this should provide an indication of the complexity of the issue, which doesn't lend itself to over-simplifications, much as we would love to rely on them.

Icke is not the only one to believe in the uselessness of lockdowns, there are many, especially among conservative and Right-oriented people, who are sceptical of their government's policies and think the same.

Now, I am in no position to categorically declare that this idea is right or wrong. As I said at the beginning, we don't have enough information.

I do have some doubts about using pure mathematics to arrive at conclusions like those of Ben-Israel on this. Correlation doesn't mean and doesn't necessarily involve causation. In Latin, this supremely logical and succinct language, it's better: post hoc ergo propter hoc is a fallacy.

For example, is it possible that countries with less contact with the rest of the world and therefore fewer opportunities for contagion (ah, the joys of globalisation! we have finally discovered them in their full glory) have had lower numbers of cases of Covid-19 and therefore had a comparable smaller need for lockdown than those with more international traffic and Coronavirus spread which as a consequence resorted more to lockdown, inverting the cause-effect direction?

Has this been considered as a contributing factor, anyway?

At least we have a glimmer of hope, though: it's the prediction on the progress of the disease in Israel made by Professor Ben-Israel on last 12 April on Facebook, which I have to reproduce in its online translation:
It turns out that the expansion of the expansion [meaning, I presume, the peak] has been behind us for about a week, and apparently it will fade almost completely in about two weeks.
Assuming the translation is accurate, we can wait about two weeks to see if his prediction for Israel materialises and test whether his theory might be correct.

Walkers, Joggers, Cyclists Coronavirus Risks Study

Jogger


I've noticed that in and around London pedestrians, joggers and cyclists don't always respect the minimum 2 metres' distance of social distancing recommended to limit the spread of Coronavirus.

The Guardian, helpfully, points out another anti-social behaviour in the streets which is more dangerous now: spitting.

But new research has uncovered that the 2 metres' distance deemed sufficient for people standing still, for example when queueing outside a shop, is not enough in times of COVID-19 when someone is exercising.

These are the conclusion of a Belgian-Dutch study.

There is some confusion among the public on this question, in view of the widespread notion, supported by the WHO (World Health Organisation), that the new virus is not spread via the air but by contact with people or surfaces. This is because the aerosols - minuscule particles floating in the air - containing the virus don't remain in the atmosphere long enough to cause a risk.

However, in a situation in which a person is walking, running or cycling after another, the droplets may still be in the air before they settle down on a surface.

Civil Engineering and Sports Aerodynamics researchers at Belgium's University of Leuven and the Netherlands' University of Eindhoven created simulations to investigate these risks.

Professor Bert Blocken, Study Coordinator of the white paper just published, in an interview to The Brussels Times explained why the measures for people standing still are "ineffective" for those walking, running or cycling:
When people speak, exhale, cough or sneeze they generate droplets, and while the largest droplets tend to fall to the ground first, the smaller ones can remain in the air a bit longer, so it is important that a person who is behind another does not walk into this cloud of droplets.
The Urban Physics, Wind Engineering, Sports Aerodynamics expert has extensively studied the aerodynamic advantages of slipstreaming in cycling, which is the act of a cyclist riding behind a team-mate or rival to save energy and thus gain a benefit: in sport terminology this is usually called "drafting".

But in the Coronavirus pandemic the disadvantages and dangers of this behaviour are remarkable.

The simulations show that the respiratory droplets of someone potentially infected with the virus could come into contact with anyone located behind him by travelling through a slipstream or wake, the area that a person in movement creates behind him.

From Blocken's simulations it appears that social distancing requirement may be smaller for two people running or walking beside each other, as the droplets land behind them. When they are positioned diagonally behind each other the risk to catch the droplets of the lead runner is also smaller. The risk of contamination is the biggest when people are just behind each other, in each other’s slipstream.

The researcher compared slipstreams to a vacuum or drag effect which occurs when the regular airflow is disturbed by someone who is in motion.

Luckily, although slipstreams can even be as long as 10-15 metres, Blocken observed that they remained quite narrow and that respiratory droplets tended to evaporate quite quickly.

Based on this study's results, the scientist advises greater social distances for people on the move:
  • those who walk in the same direction in one line should maintain a distance of at least 4–5 metres
  • for running and slow cycling the distance should be 10 metres
  • for hard, fast cycling it should be at least 20 metres
  • for overtaking, cyclists should be in a different lane at a considerable distance, e.g. 20 metres.
I don't wish to unnecessarily worry anyone, but we all should be cautious in these times of pandemic for the sake of others as well as ourselves.

Intolerant Secularists

People like Richard Dawkins, author of The God Delusion (Amazon USA) , (Amazon UK) , and Christopher Hitchens, who wrote God Is Not Great (Amazon USA) , (Amazon UK) , et al, when attacking “religion”, play on various ambiguities. They create ambiguities in their choice of terms and then these ambiguities are convenient for them.

The first instance of ambiguity is the use of the term “religion”. It puts together all sorts of people and doctrines which may have very little in common.

To give an analogy, the flat earth theory is undoubtedly a theory of physics. It says something about the earth and, by extension, is a cosmology theory because the universe in which a flat earth exists would be a different universe from ours. It is scientific because it can be tested and disproved, as indeed it has.

Now, if I wanted to criticize scientific physics, I could bundle together the flat earth theory with Newton’s classical mechanics and Einstein’s relativity theory, and say about the former things which are obviously not true about the two latter.

When Dawkins and company attack “religion”, they bundle together Muslim suicide bombers (who are among the most hated figures of our times) with Catholic and other Christian missionaries who risk disease to help the poor in African and other Third World countries.

But, from their viewpoint, it’s a good ploy. If you are not interested in truth and intellectual honesty but only in scoring points (political and non), you can use generic terms which are obviously ambiguous and create confusion by mixing “il sacro e il profano” (“chalk and cheese”). Then, by attacking the obviously bad, you have achieved the effect of also attacking the obvioulsy good in the process. And if you’re good at it, it can be as in a magic trick: nobody noticed where the card, or in this case the truth, disappeared or indeed if it did disapper at all.

Men of science like Dawkins should know that, as in science different theories redefine the concepts they use (Newtonian time and space are not the same as Einsteinian time and space), so in religion the same is true: different doctrines have different concepts of God, and they may have very little in common.

In short, you cannot criticize “religion” meaningfully, especially by extending bad aspects of terrible religions to other religions which are fundamentally good.

Another ambiguity that they employ is when they say “religion is declining in the West” or something to that effect. In that case, what they mean is clearly “Christianity” and not “religion”, given that other religions professed by ethnic minorities who live in the West do not show sign of decline.

Here they got it wrong again. Christianity still permeates Western life and way of thinking profoundly. We are all Christian, as Oriana Fallaci says. I am an atheist Christian as she is, and I’m borrowing her expression because I think it explains well the condition of our “secular” societies too.

These, and we ourselves, have been shaped by two millennia of Christian thinking, luckily. An article by John Gray on secular fundamentalists in The Guardian seems to agree with this when he says that Dawkins & co. are really expressions of the Christian background from which they derive (and he does not even defend Christianity, he just attacks Dawkins and his gang). He believes that the very idea of history as progress is Christian.

I don’t know where we would be without this profound Christian influence. Britain, which is perhaps the least Christian country in Western Europe (perhaps in the West) has also some of the greatest drugs and alcohol problems, highest level of teenager pregnancy, highest rate of illegitimate births, biggest problem of an underclass, highest crime rate, highest level of debt among the population, highest spread of obesity.

This is where abandoning our Christian roots would lead: forgetting self-discipline and only thinking of immediate self-gratification have these effects. Which is also part of the reason why, whereas it may be possible for an individual to be atheist, I don’t think that it is apossible for a society to be atheist.

When Dawkins and people of his ilk say something like “hey, look, we are a secular society now and we are fine” or something similar, they systematically forget, overlook or disregard the many, profound, pervasive ways in which many centuries of Christianity have influenced our society and still do. I can see it in myself, how my Christian upbringing still has a (mostly beneficial) effect on me.

Where the intolerant secularists also got it wrong is in putting science and religion against each other. They think that they are incompatible, whereas in fact they occupy different domains, and there is no conflict or contradiction. In fact, you may say that the problems arise when one of them tries to occupy the other’s territory, and attributes to itself a role and capability which it does not possess.

Dawkins is a good case in point. When he writes as a modern evolutionary and genetic theorist and as a zoologist, he is fine and indeed very interesting. When he writes as a self-proclaimed philosopher and a “religion basher”, he writes nonsense.

Something similar happens to science when it usurps a role which is not its own. Dawkins is a good metaphor for this arrogance and its consequences: when he tries to attributes to both himself and science a role which they do not have and a power which they do not possess, they get it all wrong. Basically, biology is his profession, and philosophy of religion is his fun activity, his hobby. I would call him a religion basher by hobby. He definitely should stick to his profession, because he is rubbish at his hobby.

We have to be careful that science does not overstep its domain and role, because many bad things may easily follow from this.

Positivism was a 19th century philosophy which overstressed the power and importance of science. The French positivist sociologist August Comte thought that humanity goes through three stages: "the Theological, or fictitious; the Metaphysical, or abstract; and the Scientific, or positive."

Gray's article does not mention him but mentions the anthropologist James George Frazer instead, who slightly altered and popularized Comte’s theories His three stages are: primitive magic; religion; and science.

All this leads to scientism, the belief that the scientific method can be applied to everything and that science is the most authoritative and valuable learning activity to the exclusion of other viewpoints.

We can easily give too much power to science, as the case of animal experimentation clearly and tragically shows. Most people in the West probably are morally, instinctively opposed to vivisection, but they just accept it because “scientists say that it’s necessary” without even trying to question whether that statement by scientists is true or not.

Technocracy, government by scientists and technical experts, is just as bad as any other form of control by an elite.
