Of course COVID-19 has consumed the news cycle for some time. Of late, we have seen protestors against lockdowns in Lansing, Michigan brandishing assault rifles. We have seen various marches against various aspects of what I will call ‘common sense’ proceedures to prevent the spread of COVID-19. One of my university professors challenged me on the use of the term because there is no such thing as ‘common sense’. If sense were common, we would not have the troubles we have now.

Below is a clip from Trevor Noah talking about wearing masks. And he is funny as usual. I have to confess that for years, pre-pandemic times, I have questioned the need to wear a mask during the flu season. I thought people looked strange wearing a mask. Now, I wonder why it took me so long to realise that wearing a mask out in public (as well as when I clean the cat box) is a good policy. Now you won’t see me in public without my mask and gloves. Enjoy Trevor Noah, the masked avenger!

The world is dealing with an unprecedented health crisis caused by a new virus. With new insights in the way COVID19 spreads, in the way the virus behaves and in the way to deal with the pandemic every day, it is now more important than ever to safeguard the information we share is accurate and fact-based. We have to inoculate ourselves against the fake news and misinformation that infect our newsfeeds and timelines at this crucial moment by fact-checking.

For the duration of the pandemic, I will try to give you an overview of the main issues in CoronaCheck, an Australian email newsletter with the latest from around the world concerning the coronavirus.*


TO CREATE OR NOT TO CREATE

Fact-checkers at AAP, AFP and Snopes debunked social media posts which claimed Tasuku Honjo, Nobel Prize winner in Physiology and Medicine in 2018, said the novel coronavirus was “not natural”, as it spreads in both hot and cold climates, and that it was”manufactured in China”.

Professor Honjo was quoted in these posts as having said: “I have done 40 years of research on animals and viruses. It is not natural. It is manufactured and the virus is completely artificial.”

Fact-checkers at AFP were unable to find any record of Professor Honjo making these remarks, and the professor himself issued a statement saying he was “greatly saddened that my name and that of Kyoto University have been used to spread false accusations and misinformation”.

 

ANOTHER PRESIDENT LIES

According to the BBC, President Andry Rajoelina of Madagascar officially launched an unproven herbal remedy by claiming the tea had already cured two people in the country, prompting people to queue for their supply of the free beverage.

According to Mr Rajoelina “This herbal tea gives results in seven days.”

But the World Health Organisation doesn’t recommend “self-medication with any medicines … as a prevention or cure for COVID-19” and in a report, the Bangkok Times, authored by AFP, has the US Centers for Disease Control and Prevention note: “There is no scientific evidence that any of these alternative remedies can prevent or cure the illness caused by COVID-19. In fact, some of them may not be safe to consume.”

 

MASKS UNMASKED

Image source: Facebook

An infographic, purporting to show the effectiveness of face masks, claims a healthy person wearing a mask has a 70 per cent chance of being infected with the coronavirus by a sick person not wearing a mask. When mask-wearing is reversed, the apparent “contagion probability” falls to 5 per cent. When both healthy and sick people are fitted with masks, the chance of the healthy person of being infected is supposedly just 1 per cent.

Fact-checkers at Snopes and Reuters found that the information was mostly false**, as there was no scientific consensus of the efficacy of face masks nor data to support the quoted percentages. It was also unclear whether the post referred to surgical masks, homemade masks or N95 respirator masks.

However, as reported by Snopes, the US Centers for Disease Control and Prevention say that masks helped by “strengthening the social distancing that we are already doing”.

** The infographic made its appearance on Politics Plus too but with the footnote that the commenter who posted it could not vouch for the accuracy.

 

NO COVID-19 VACCINE YET

Image source: Facebook

Fact-checkers at Full Fact and factcheck.org have debunked a post shared on Facebook that falsely suggests a vaccine exists for the novel coronavirus.

In the post, a caption accompanying the photo of a vaccine vial states: “Now this was 2001 tell me why 19 years later they say there is no vaccine.”

However, the label on the vial clearly states “canine coronavirus vaccine”.

As may be known by now, coronaviruses are a family of viruses. The current outbreak relates to the novel coronavirus SARS-CoV-2, which causes COVID-19.

According to Full Fact: “Canine coronavirus doesn’t affect people, [but dogs] and is a gastrointestinal disease, not a respiratory one.”

 

NOT MADE IN CHINA EITHER

Image source: Twitter

A video in France has been shared with a misleading caption suggesting the faulty gear was made in China.

One version of a video, showing brand new medical gowns disintegrating in France, has been shared on Twitter and retweeted more than 250 times, is captioned: “Protect our doctors & nurses by not buying medical supplies from bloody #China!”, AFP Fact Check has found

But a spokesperson of the hospital featured in the video told AFP that the gowns were not made in China. Rather, they were French-made gowns that had been damaged while in storage in a humid place.

AND FROM WASHINGTON D.C.

US President Donald Trump’s recent claim that the US had done more testing for COVID-19 than “every country combined” has been rubbished by fact-checkers at factcheck.org.

When Mr Trump claimed on April 28, the US had carried out almost 6.03 million tests for the disease, which indeed is more than any other country but not more than all other countries combined, with more than 25 million tests administered outside the US.

When related to its population, the US is lagging behind other countries with 20,940 tested per million compared to for example 24,733 tested per million in Australia. Mr Trump may be aware of this and wants to conduct a suggested 5 million COVID-19 tests per day. However, the top US official in charge of testing, Admiral Brett Giroir, said that was not feasible with the current technology.

“There is absolutely no way on Earth, on this planet or any other planet, that we can do 20 million tests a day, or even five million tests a day,” Time magazine reported the testing czar as saying.

In its 56-page “roadmap” for a return to normalcy, a Harvard University study had suggested the US would need to conduct at least 5 million tests a day by early June, and 20 million per day by late July, something Giroir claimed was “an Ivory Tower, unreasonable benchmark”.

 

THE R NUMBER

Authorities in Germany and many other countries like Australia are paying very close attention to the rate of the spread of COVID-19, using the reproduction number or ‘R’ value as an important reference. The number indicates how many people one person with the virus can infect. For instance, if the rate is equal to 1, it means that one person is infecting – on average – one other person. Mary Colombel explains the logic behind the number.

Armed members of the Republican Party, took-up and loaded their assault weapons, donned their Nazi and pro-Trump* paraphernalia, and terrorized the Michigan State Capital in Lansing, over their protest opposing protecting the people of Michigan against Trump* virus.  They demonstrated that the Republican Party is the greatest terrorist threat faced by America today.

Hundreds of protesters, some armed, gathered inside Michigan’s state capitol on Thursday as state lawmakers debated the Democratic governor’s request to extend her emergency powers to combat coronavirus.

A tightly packed crowd of protesters, some carrying rifles, attempted to enter the floor of the legislative chamber, and were held back by a line of state police and capitol staff, according to video footage posted by local journalists.

“Let us in! Let us in!” the protesters chanted, as they stood shoulder-to-shoulder inside the statehouse. Few of them were wearing face masks.

Some of the protesters shouted anti-government slogans, including comparing the state’s Democratic governor, Gretchen Whitmer, to Hitler…

Any time Republicans, especially when goose-stepping with their beloved criminal Fuhrer Trump*, compare a Democrat to Hitler, we have a classic example of projection.

AUSTRALIA’S TRUMP AND HYDROXYCHLOROQUINE

Australian billionaire businessman and former federal MP Clive Palmer took out back-to-back full-page advertisements in the Murdoch press this week announcing that his foundation had purchased 32,900,000 doses of the antimalarial drug hydroxychloroquine and that he’s donating them towards Australia’s fight against COVID-19.

In his advertisements, Mr Palmer implied that there is a link between a decision taken by Health Minister Greg Hunt four weeks ago to make hydroxychloroquine available to doctors who are treating COVID-19 patients and Australia’s death rate since then from the virus. Mr Palmer claimed that it was the “lowest in the world” while acknowledging “the [infections] curve has flattened”. The Australian government, however, credited the low infection and death rates to basic hygiene measures.

Hydroxychloroquine received global attention after US President Donald Trump tweeted that it would be a “game-changer” in the fight against the coronavirus, based on small, preliminary trials in China and France, and maintained that the federal government had purchased and stockpiled 29 million pills of the drug. Since then Mr Trump’s attention has shifted first to internal cleansing with antiseptics and now to Remdesivir, an anti-viral drug, something Mr Palmer seems not to have caught up with.

As for hydroxychloroquine, Australian Medical Association federal vice-president Zappala said the published evidence remained “very mixed” and it was unclear whether the drug would be effective beyond its current approved limited use, which includes treatment of lupus and rheumatoid arthritis. In a recent US study, researchers essentially found a higher death rate in patients treated with hydroxychloroquine alone, while the drug also risked serious side effects, especially for people with pre-existing heart conditions.

Some background to Clive Palmer may make his actions a little clearer. Billionaire Palmer has iron ore, nickel and coal holdings;  by 2019 his estimated wealth had increased to A$4.09 billion. Besides mines, Mr Palmer owns real estate and several golf courses.

Mr Palmer created the Palmer United Party in April 2013, winning the Queensland seat of Fairfax in the 2013 Australian federal election and sitting as an MP for one term. During that term, he was the least-attending MP.

In 2009, he bought Queensland Nickel and the Palmer Nickel and Cobalt Refinery when it was about to be closed. In the first year after purchasing the refinery, Palmer gifted staff 50 Mercedes Benz cars and thousands of overseas holidays after the refinery turned a huge profit. On 18 January 2016, Queensland Nickel went bankrupt. Palmer refused to pay the entitlements of workers who lost their jobs, stating that “I have no personal responsibility, I retired from business over three years ago”. He also blamed the administrators for sacking the workforce. This forced the Federal Government to cover the workers’ entitlements.

In 2018 Clive Palmer tried to return to politics as a Senator in the Federal Parliament. He did not succeed but by pumping millions in campaign ads, he made sure the Labor Party lost its foothold in Queensland and the election. At the moment, Labor has a slim majority in Queensland’s State Parliament; in November new elections will be held in Queensland but due to the COVID-19 pandemic, it is unclear what form they are going to take. But one thing is clear: Clive Palmer has donated 32,900,000 doses of the antimalarial drug hydroxychloroquine to Australia…

 

WAR ON BILL GATES

Microsoft founder, philanthropist and world’s third-richest man Bill Gates has the subject of a overwhelming volume of misinformation related to COVID-19. It started in January with claims the Gates Foundation had predicted 65 million deaths in a pandemic simulation (it didn’t) and have been followed with claims that a Gates Foundation-funded vaccine paralysed nearly 500,000 children (also false) and that Mr Gates is being sued by India (wrong again).

In another example, a Facebook post claimed Mr Gates was freely able to prescribe drugs. However, given Mr Gates is not a medical doctor, the claim was rated false by fact-checkers at Lead Stories. Mr Gates is also not trying to “microchip” the world’s population through a coronavirus vaccine, nor is he using invisible tattoos and monitoring bracelets to track Americans.

And the Gates Foundation, despite helping the vaccine search with up to $250 million in funding, doesn’t hold a patent for such a jab.

 

FACEBOOK PRACTICES ARE STILL LACKING

In the same week that Mark Zuckerberg boasted that his company had “taken down hundreds of thousands of pieces of misinformation related to COVID-19”, reporters at The Markup were allowed to place ads on both Facebook and Instagram targeting an ad category of 78 million users who were deemed interested in pseudoscience, “advantage of this sort of vulnerability that a person has once they’re going down these rabbit holes, both to pull them further down and to monetise that”, according to Kate Starbird, a professor at the University of Washington.

Facebook has since removed the pseudoscience category from its ad manager.

NewsGuard, an online trust tool, also found Facebook’s misinformation-fighting practices to below par, identifying 31 Facebook pages, with an audience of 21 million people, as “super-spreaders” of coronavirus misinformation spreading “blatant misinformation”, even where there was evidence of coordinated inauthentic behaviour, which violates Facebook’s policies.

 

FROM AMERICA, STILL

Image source: Facebook

Trump supporters have taken to social media to defend his musings that “powerful light” and disinfectant could be used to kill the novel coronavirus inside human bodies.

One such Facebook post claims that Mr Trump was referring to “Ultraviolet Radiation” administered into the body when he talked of internal disinfectant. “Just because it’s called a ‘disinfectant’ doesn’t mean it’s Pine-Sol,” it claimed. “Ultraviolet Radiation” is a method that kills bacteria and has been “used for a while now”, according to the post.

PolitiFact found that while the post may be referring to a treatment called “ultraviolet blood irradiation”, used mainly in the alternative-medicine community, there was no evidence such treatments could kill viruses or bacteria.

 

FROM WASHINGTON, D.C.

According to Politico, a report by the US State Department warned that Russia, China and Iran were using the coronavirus pandemic to launch a “disinformation onslaught” against the US by echoing one another.

Messages spread by the three include that the coronavirus is an American bioweapon, that the Chinese response to the virus was superior to that of the US, and that the US economy wouldn’t be able to handle the crisis, and they were pushed by state-run media outlets, as well as governments themselves. In one example, a website run by the Russian Defence Ministry is said to have promoted a conspiracy theory that Bill Gates had a hand in creating the virus.

The State Department reported the coronavirus pandemic had accelerated the convergence of disinformation narratives.

Deputy criminal Fuhrer, Vice Resident Mike Pence, insulted the eyes of the nation today by refusing to wear a mask in the Mayo Clinic, proving that the Republican Reich is the place where ugly and stupid meet.

0429PenceNoMask

As Americans continue to seek answers about the ongoing coronavirus pandemic, Stephen Colbert offered some advice Tuesday night: Maybe it’s time to stop listening to Vice President Pence.

Just hours earlier, Pence, who leads the White House’s coronavirus task force, prompted a collective outcry when he was spotted speaking to staff and patients at the Mayo Clinic in Rochester, Minn., without a face mask. Many, including Colbert, noticed Pence seemed to be the only person at the medical center who wasn’t wearing some sort of face covering — an apparent violation of the clinic’s policy and a move that appears at odds with federal guidelines dictating best practices for stemming the spread of the novel virus.

“Hold on, I’ve got a mask for you right here,” Colbert said on his CBS show, staring defiantly into the camera while appearing to make a crude gesture with his hand, which was wrapped loosely in a surgical mask.

Colbert wasn’t the only person who objected to seeing the lower half of Pence’s face Tuesday. The late-night host was joined by fellow TV comics and medical professionals, all of whom roundly criticized Pence for failing to set the right example amid the pandemic by knowingly disregarding the hospital’s masking policy.

By early Wednesday, Pence’s name and “Mayo Clinic” were trending on Twitter as critics slammed the vice president for promoting “completely irresponsible public health messaging.”…

Pence Blasted For Defying Mayo Clinic Face Mask Rule During Visit

On the other hand, Pence could be doing us a favor.  First, having Pence serve jail time in a cremation urn than in a prison cell.  Second, if we’re really lucky, Pence might spread Trump* virus to criminal Fuhrer Trump*.  Of course, I’m employing satire, but it is a lovely thought!

SHE’S ALIVE

Elisa Granato, one of the first recipients of a trial vaccine for COVID-19 at the University of Oxford, has been the subject of false reports that she had died shortly after receiving the vaccine last week, Full Fact and Reuters have found.

However, Dr Granato (she’s a scientist herself) tweeted at the weekend that she was “doing fine” while the university stated in response to a Reuters’ query which confirmed that she was “alive and well”. The UK Department of Health and Social Care also tweeted that the news was “completely untrue”.

Dr Granato is one of the 800 participants who will either receive the trial vaccine or a control vaccine as part of the study.

ANTI-VAXXERS ON THE WARPATH AGAIN

Image source: Facebook

The Facebook post, which was shared in the US, Canada and Australia, offered advice on “how to legally decline a vaccine” but has been debunked by fact-checkers at AFP and Lead Stories.

The post suggests people should ask whether a vaccine (and presumably any future COVID-19 vaccine) contains “MRC-5” and whether it this could lead to an “iatrogenic reaction”. If the doctor administering the vaccine answers in the affirmative, as their Hippocratic Oath compels them, then a person apparently has the right to decline. “This is how we can legally (and respectfully) decline their offered mandated services and there is absolutely NOTHING they can do about it!”

But AFP found that while there were ways to refuse a vaccine legally in either the US, Canada or Australia, they were not those listed. For example, some Australian states mandate vaccinations for children enrolling in childcare or school, however, the vaccination itself is not compulsory and people maintain the right to choose whether to receive a vaccination.

 

SCAMMED

In Australia, digital scammers are using the coronavirus pandemic to con them into buying goods, sharing personal information and installing malicious software on their computers. This may well be the case in other countries too.

The Australian Competition and Consumer Commission (ACCC) says that since the beginning of the COVID-19 outbreak, it has received more than 1000 reports of bogus coronavirus-related schemes by scammers impersonating banks, retail stores, and the Tax Office, while the Australian Cyber Security Centre (ACSC) has warned of scams involving fake Post emails.

In one case study detailed by the centre, a US-registered cyber attacker managed to send text messages to Australian phones looking as if to have come from official ‘myGov’ sources. The link in the message led to a website hosting a banking Trojan known to target Android phones to steal personal financial information.

 

FROM AMERICA

Image source: YouTube: Fox News

Comparisons between the coronavirus and various causes of death have been rife around the world with commentators, politicians and CEOs pushing for economies to reopen and for a return to business-as-usual.

One such comparison was made by TV’s “Dr Phil” — real name Phil McGraw —claiming during a Fox News interview that 45,000 Americans die every year in road accidents, 480,000 from smoking and 360,000 in swimming pools. The first two numbers were correct but, in reality, only 3,709 drowned in 2017, including those people who drowned in natural bodies of water and baths, not just swimming pools. An overstatement US by almost 10 times the actual figure, as PolitiFact found.

However, these apples-and-oranges comparisons are beside the point according to Arthur Caplan, the founding head of the division of medical ethics at the New York University School of Medicine.
“The issue isn’t how many people die of car crashes or swimming pool accidents or strokes or whatever. The question is whether they all happen at once and overwhelm the healthcare system.”

Given the massive amount of attention already given to Mr Trump ponderings whether disinfectant could be injected into the body to kill off the virus, or whether “very powerful” light could be a potential treatment, I will refrain from a detailed debunking of his suggestions here.

 

Things that don’t cure and/or prevent COVID-19**

Everyday Erinyes #212

 Posted by at 8:39 am  Politics
Apr 252020
 

Experts in autocracies have pointed out that it is, unfortunately, easy to slip into normalizing the tyrant, hence it is important to hang on to outrage. These incidents which seem to call for the efforts of the Greek Furies (Erinyes) to come and deal with them will, I hope, help with that. As a reminder, though no one really knows how many there were supposed to be, the three names we have are Alecto, Megaera, and Tisiphone. These roughly translate as “unceasing,” “grudging,” and “vengeful destruction.”

Yippee! We are back up!

I thought about posting this Wednesday when we got back on line, but I was feeling a little dizzy myself. (Whatever it was, it wasn’t COVID-19. I checked that out six ways from Sunday. I suspect it was something I ate Tuesday.) In any case, I’m glad I chose not to. I hope this way it will be easier to stay out of all the other great minds’ ditches. It’s in the category of “News You Can Use.” And I’ve added a couple of videos which Nameless found (and I am assuming he won’t mind me posting them here since he hasn’t done so here yet.)

Making masks at home – what you need to know about how to reduce the transmission of coronavirus

The recent Centers for Disease Control and Prevention recommendation to use cloth face coverings to help slow the spread of COVID-19 has generated numerous how-to articles and videos. As academics who focus on personal protective equipment (PPE) research and development, we are concerned about the lack of information about two critical features of home mask design: fit and fabric selection.

The reality of particle size

Virus particles are tiny, ranging from 0.1 to 0.3 micron. A size 40 micron particle is visible with the naked eye – anything smaller, you need specialized equipment to see it.

Protective masks like the N95 are designed to prevent virus particles from flowing in and out of the mask. Due to current shortages, N95 masks should be reserved for COVID-19 health care workers only.

Better than nothing

Homemade masks cannot block or filter the SARS-CoV-2 virus, because it can easily flow through every common material people have at home. However, a homemade mask is still better than none at all. If made correctly, a homemade mask can reduce the transmission of the virus from the wearer to others by impeding large droplets and spray produced by a cough or sneeze. It can also reduce the transmission of the virus from others to the wearer.

Fit

Masks should completely cover the nose and mouth. When measuring for a mask pattern, make sure it extends from the top of the nose – as close as possible to the eyes without obstructing sight – to under the chin. Masks should cover the face side-to-side, well past the opening of the mouth.

When developing prototypes, check around all edges of the mask for gaps. If you see any, close them up by pinching the fabric together, and stitch or tape or staple edges together to create a pleat or dart. A thin metal wire or paper clip placed along the top edge of the mask can stabilize and shape it along the bridge of the nose and cheekbone for a closer fit.

Masks should stay securely in position and fit comfortably with ties or elastic ear loops. If the mask is too tight or loose, the wearer may continuously adjust the mask forgetting the admonition – “Don’t touch your face!”

The ties and loops should also be the mechanism for taking off the mask, as the front of the mask might be contaminated.

Fabric selection

People have varying access to different fabrics at home. Masks should incorporate fabrics that:

  1. Reduce virus transmission to and from the nose and mouth

  2. Wrap around the face and are comfortable next to the skin

  3. Are easy to wash and sanitize.

Fabric is comprised of four variables that must be considered for mask making: fiber, yarn, structure and finish. Change a variable – and mask performance changes.

Variables that make up a fabric. Susan L. Sokolowski and Karen L. LaBat, CC BY

Fibers are the smallest component of a fabric. They cannot be identified by sight or touch. Look for a fiber content label on the products or fabrics you might use for your mask. Alternately, a “burn test” can be used as a crude method to determine if a fabric is a natural fiber, human-made fiber, or a blend of natural and man made fibers. If you choose this method be careful.

There are three important fiber characteristics to consider for mask making. The first is micron size – the diameter of a fiber. The SARS-CoV-2 virus particle is 0.1 to 0.3 micron, so small-sized fibers allow for more compact fabric structures to reduce transmission. The second is how the fiber feels next to skin – this will indicate how comfortable a mask may feel next to your face. The third is moisture regain – how well the fiber absorbs moisture. A higher number means more absorbency; low regain gives a sense of how well the fiber might repel moisture.

Generic fiber characteristics and mask considerations. Susan L. Sokolowski and Karen L. LaBat, CC BY

Fibers are twisted together to form yarns. Yarns vary in size affecting fabric thickness and breathability. “Yarn count” is the number of yarns in a 1-inch square of woven fabric. A high yarn count fabric indicates a dense fabric with droplet blocking potential. Yarns with different properties can be blended to combine characteristics.

Yarns are then structured into the physical fabric.

Types of fabric. Susan L. Sokolowski and Karen L. LaBat, CC BY
Structures and mask considerations. Susan L. Sokolowski and Karen L. LaBat, CC BY

Performance finishes, like water repellency and antimicrobials, are not visible but could be helpful. Detect water repellency or moisture wicking by using an eye dropper to place a drop of water on a fabric to see how it moves across the fabric. Aesthetic finishes like graphics and batik are not so useful.

Put it all together

There are many fabric variables to reckon with for a homemade mask. Consider building a three-layer system.

Three-layer mask system considerations. Susan L. Sokolowski and Karen L. LaBat, CC BY

This three-layer system includes a space between the inner and outer layers for a removable middle layer. A replaceable “filter” is inserted in that space. If one fabric layer is too thin, add additional layers for protection.

Homemade masks will not filter the SARS-CoV-2, however, masks may prevent droplets and spray from transmitting between individuals. When wearing a mask, remember to continue social distancing, wash hands frequently and wipe down surfaces and packages.

Knowing how masks are made helps in choosing and using them, even if you aren’t making them yourself. Notice how everything you’ve seen here, and just about everywhere else, is about making or getting them, and putting and keeping them on. But taking PPE off matters too. These are the videos which Nameless found:
