Another Call for Face Masks

Should people don face masks when they go out in public? The question has caromed around the Internet with many conflicting opinions. A previous contributor to Bacon’s Rebellion has argued that Virginians should wear them. Contributor Hans Bader agrees. — JAB

You should wear a mask when you leave the house. In East Asia and the Czech Republic, huge numbers of people now wear masks, and that has greatly reduced the spread of coronavirus. Mask-wearing isF a key reason why the virus spread less in East Asia than in Western countries like Italy, Spain, and the United States.

“More Americans should probably wear masks for protection,” notes the New York Times. “Places like Hong Kong and Taiwan that jumped to action early with social distancing and universal mask wearing have gotten their cases under much greater control.” The Times quotes Dr. Neil Fishman, the chief medical officer of the University of Pennsylvania hospital, explaining that “if everyone in the community wears a mask, it could decrease transmission.”

You don’t need a medical-grade mask to reduce the odds of spreading coronavirus — if you can’t find one on the market, you can even make your own at home, as many Czech people did. As Jeremy Howard notes, “The community response in Czech Republic was amazing. People made their own masks at home, and then hung them on ‘mask trees’ for anyone in their community to use.”

Such a home-made mask won’t provide as much protection as a medical-grade mask, but it will protect you better than wearing no mask at all. Most of the benefit from a home-made mask is in keeping wearers who are sick, or not yet sick but unknowingly carrying a virus, from giving the virus to other people. But such a mask also protects the wearer a little against catching the virus.

As Science Magazine notes, “Health authorities in parts of Asia have encouraged all citizens to wear masks in public to prevent the spread of the virus, regardless of whether they have symptoms. And the Czech Republic took the uncommon step last week of making nose and mouth coverings mandatory in public spaces, prompting a grassroots drive to hand make masks.”

Western health officials are belatedly admitting that people should wear masks when they go out in public. “After months of denial, German medical officials now call on people to wear makeshift masks in public to reduce contagion,” notes Bojan Pancevksi. Former FDA Commissioner Scott Gottlieb says the federal government “should consider telling people to wear masks in areas of epidemic spread.” For those “consumers who don’t already have masks,” Dr. Gottlieb suggested that the Centers for Disease Control provide guidance “on how” they can “make cotton masks.”

But earlier, when coronavirus was less widespread, Western health officials sang a different tune. For example, on February 27, the CDC told ordinary people they didn’t need to wear masks. It tweeted, “CDC does not currently recommend the use of facemasks to help prevent novel #coronavirus. Take everyday preventive actions, like staying home when you are sick and washing hands with soap and water, to help slow the spread of respiratory illness.”

This was an odd recommendation, because the public does benefit from ordinary people wearing masks. Research shows wearers do get some protection from masks, even when they are not medical-grade. More importantly, people around mask wearers benefit a lot, if the person wearing a mask is sick, or asymptomatic (carries a virus, but does not know it or have symptoms yet). The CDC is widely believed to have downplayed the need for masks, despite their usefulness in protecting against infection, as a way to keep ordinary people from buying up medical-grade masks needed by doctors and nurses.

Healthcare workers clearly do benefit from masks. As Quartz points out, the scientific “literature is unequivocal on one point: Masks protect healthcare workers from high levels of viral pathogens. From the lowly paper mask to ultra-high filtration N-95 masks designed to stop aerosols, decades of studies show masks stop healthcare workers from getting infected in hospitals, and prevent sick people from spreading disease to others.”

Ordinary people benefit from wearing masks, too, although not as much as healthcare workers. As Dr. Zeynep Tufekci notes in the New York Times.

Masks work — maybe not perfectly and not all to the same degree, but they provide some protection. Their use has always been advised as part of the standard response to being around infected people, especially for people who may be vulnerable. World Health Organization officials wear masks during their news briefings….health officials in many high-risk Asian countries had advised wearing masks…

It is of course true that masks don’t work perfectly, that they don’t replace hand-washing and social distancing, and that they work better if they fit properly. And of course, surgical masks (the disposable type that surgeons wear) don’t filter out small viral particles the way medical-grade respirator masks rated N-95 and above do. However, even surgical masks protect a bit more than not wearing masks at all. We know from flu research that mask-wearing can help decrease transmission rates along with frequent hand-washing and social-distancing. Now that we are facing a respirator mask shortage, the federal Centers for Disease Control and Prevention is recommending that surgical masks are “an acceptable alternative” for health care workers — again, obviously because some protection, even if imperfect, is better than none….

The W.H.O. and the C.D.C. told the people to wear masks if they knew they were sick. However, there is increasing evidence of asymptomatic transmission, especially through younger people who have milder cases and don’t know they are sick but are still infectious. Since the W.H.O. and the C.D.C. do say that masks lessen the chances that infected people will infect others, then everyone should use masks. If the public is told that only the sick people are to wear masks, then those who do wear them will be stigmatized and people may well avoid wearing them if it screams, “I’m sick.” Further, it’s very difficult to be tested for COVID-19 in the United States. How are people supposed to know for sure when to mask up?

… Places like Hong Kong and Taiwan that jumped to action early with social distancing and universal mask wearing have the pandemic under much greater control, despite having significant travel from mainland China. Hong Kong health officials credit universal mask wearing as part of the solution and recommend universal mask wearing. In fact, Taiwan responded to the coronavirus by immediately ramping up mask production.

Given the clear benefit of wearing masks, why did some health officials downplay the benefit of wearing them?

As Alex Nowrasteh of the Cato Institute notes, “The arguments against mass use of face masks were noble lies intended for the good reason of attempting … to conserve them for healthcare workers. However, they backfired quickly [and that] will cause even more harm down the line.”

Similarly, Dr. Tufekci says, “Many health experts, no doubt motivated by the sensible and urgent aim of preserving the remaining masks for health care workers, started telling people that they didn’t need masks or that they wouldn’t know how to wear them.”

But as Nowrasteh notes,

Those claims were simply untrue. Yes, healthcare workers need masks, but masks also reduce transmission outside of hospitals and clinics. Sick people who wear masks reduce their likelihood of transmitting the virus and healthy people who wear them reduce their likelihood of becoming infected. Tufecki pointed out the obvious contradiction: If masks don’t work, why do healthcare workers need them?

Yet some people in the West have an ingrained bias against wearing masks. As one woman put it on Twitter, “Baffled by people walking around our local grocery store with masks on. If you have symptoms or are at risk, get the hell out of the grocery store.”

But refusal to wear masks will cost many lives. As Market Urbanism notes, the West may “decimate” its “elderly population because we’re too pig-headed to learn anything from Asian countries that’ve already” curbed coronavirus by wearing masks. “Please don’t go shopping in the midst of a respiratory virus pandemic without covering your mouth and nose!”

Don’t worry about running out of masks. Masks can be reused. As Jeremy Howard observes, “you can reuse your masks. Stanford University research shows that you can just pop them in the oven at 70C (160F) for 30 mins, and they’re good to go.” By reusing masks, or making your own, you won’t be using up the supply of masks needed by doctors.

For all these reasons, health officials should stop minimizing the benefit of wearing masks. As Nowrasteh observes, “Experts lying about COVID-19, such as saying that facemasks don’t make a difference, do far more harm than they realize. Don’t lie, even if you think it is for noble purposes.”

Minimizing the benefit of masks is hardly the biggest blunder of the Centers for Disease Control. As the New York Times chronicles, the CDC’s bureaucratic bungling delayed a meaningful response to the spread of coronavirus by a crucial month, enabling the disease to get a foothold in many parts of the United States. As the New Yorker notes, “The three-week delay caused by the CDC’s failure to get working test kits into the hands of the public-health labs came at a crucial time. In the early stages of an outbreak, contact tracing, isolation, and individual quarantines are regularly deployed to contain the spread of a disease. But these tools are useless if suspected cases of a disease cannot be tested. The void created by the CDC’s faulty tests made it impossible for public-health authorities to get an accurate picture of how far and how fast the disease was spreading. In hotspots like Seattle, and probably elsewhere, COVID-19 spread undetected for several weeks.”

As the Times explains, bureaucrats at the CDC and FDA stymied private and academic development of diagnostic tests that might have provided an early warning and a head start on controlling the epidemic that is now spreading across the country. Seattle infectious disease expert Dr. Helen Chu had, by January, collected a huge number of nasal swabs from local residents who were experiencing symptoms. She proposed testing those samples for coronavirus infections. But the CDC told Chu she could not test the samples unless her laboratory test was approved by the FDA. The FDA refused to approve Chu’s test on the grounds that her lab “was not certified as a clinical laboratory under regulations established by the Centers for Medicare & Medicaid Services, a process that could take months.”

In the meantime, the CDC required that public health officials could only use the diagnostic test designed by the CDC itself. That test turned out to be badly flawed. The CDC’s demand for centralized control over the testing process greatly slowed down the process of disease detection.

  1. The only masks I have are a couple of Korean War vintage gas masks….

  2. Don’t need to convince. Apparently the whole issue was the fear that if it was suggested that people would act like idiots and immediately go out and hoard as much as they could.

    And on the tests. Would we want to do it the way that South Korea and Germany did it or some decentralized way?

    Isn’t there a need for a standard test and a standard protocol and standard reporting? How can that work if multiple entities do it differently?

    How can you even compare two adjacent states if they do it different?

  3. Thankfully my better half is a Quilter (and a Liberal, but I digress). She has made quite a few masks already.

    I am especially moved by the LATimes story of an adult choir in Washington state that had a rehearsal on March 10th and 45 of 60 people got the COVID. Our community Band also rehearsed last on March 10th, lucky apparently.

    WTOP radio had someone from Italy this morning saying apparently COVID is more contagious than thought, and it also appears normal air transmission is possible without need for sneezing and coughing. Yikes!

    The use of face coverings is all over this story about how the shipyard is managing to stay open. Paywall, but this is first day of the month. Nice to see several people I know quoted, including Dru Branche, who I first met when she was a construction superintendent on the Bush, and CEO Petters (mentioned him yesterday). The yard is the coolest place in the world.

    I mean, gee, where are we supposed to get a supply? Happy to do it, but where? I haven’t refused to wear one, I can’t find them!

    Yes, TBill, that’s the whole point about this bug. It lingers. They found it active on the cruise ship what, 17 days after it was evacuated? That’s what my nurse practitioner daughter finally beat into my head. She’s been shouting it’s airborne for two weeks! And without question, the real issue once we’re past the crisis will be, who dropped the ball on testing and how. Right now its all rumor and innuendo, but we’ll need to KNOW.

  5. From what I have been reading lately, there are three other reasons why masks are now being recommended, both of which were not widely understood before:
    1. The virus can be spread by droplets in the air, especially at close range or in tight quarters.
    2. A relatively large, as much as 25 percent, of those infected will not show symptoms, thereby spreading the disease without knowing it.
    3. A person can be infectious two or three days before showing symptoms.

    I had not heard the information that it can remain active on surfaces for long periods. I have operating on the earlier information that it “dies” after two or three hours on most surfaces.

    One question I have, which I have no yet seen addressed is: If someone is asymptomatic, how long does he remain infected? For example, if someone were tested positive, but showed no symptoms and felt fine, would he still test positive 14 days later, 30 days later? Now, we are saying that if someone has tested positive, he should quarantine for 14 days. Do we know that is long enough?

    • What I’ve seen, remain self quarantined 14 days from onset of symptoms at least. If you never show symptoms, how would you know? So the are saying remain out of circulation for 14 days after known exposure to another positive.

      Your comments are fascinating, because I’ve clearly heard for a long time this sucker remains active on surfaces, and depending on the surface it can be days. What remains controversial is, is it truly airborne or just the droplets? Airborne means you don’t to be sneezing or coughing to spread it. You have it, you rub your nose, you open a door and leave it on the handle…

      As to testing, the antibodies are going to show up the rest of your life. Be glad of that!

    Class 6 felony unless the Governor waived this. Otherwise you are going to need a doctors note to wear a mask and be in good standing with the Code of Virginia.

    https://law.lis.virginia.gov/vacode/title18.2/chapter9/section18.2-422/

    • I don’t think the Governor would have to issue the waiver. The wearing of a mask is a felony if the wearer does so with the “intent to conceal his identity.” If you go to the grocery store with a ski mask that has mouth and nose holes, you may have some trouble convincing a cop or prosecutor that you were not trying to hide your identity, but just protecting yourself from the virus. On the other hand, a surgical style mask that covers only your nose and mouth should not get you into trouble.

    • johnrandolphofroanoke

      The old law was rarely enforced. I think it was a way for authorities to draw a law for Klan activity.

  7. “Class 6 felony unless the Governor waived this.”

    Wow. My full-face motorcycle helmets cause “a substantial portion of the face [to be] hidden or covered so as to conceal the identity of the wearer”.

    Interesting. Apparently, I have been unknowingly committing a felony for almost four decades.

    I guess I’ll have to start riding without a helmet…

    • Nice try, but it won’t work, primarily because the law explicitly requires you to wear a helmet. You are not doing it with the “intent to conceal your identity,” but because the law requires you to.

      • If they were going to care, we’d know by now. If you got it, wear it! (Don’t got one, myself.) That’s an anti-KKK law. Some folks might be surprised Virginia actually passed anti-Klan laws back in the day….

      • Yes, I know. It HAS been tried (although not be me).

        Along those lines, though, I once had a gas station clerk refuse to serve me because I still had on my helmet when I went in to pay for gas. I had the face-shield flipped up so he could see my eyes and nose, but he claimed he could not serve me because I was concealing my identity (he said it was a company policy).

        I told him that since I had already pumped the gas he had two choices:

        1) He could take my money, or
        2) He could continue to refuse to take my money, and I would interpret his continued refusal as him granting me permission to leave without paying.

        He took the money.

  8. Not sure where I’d get a mask given that all the stores are closed. Maybe Amazon has some. Or, I could improvise. I could wrap a bandana around my face before I go into the local liquor store out here in rural Maryland. Hmmm … On second thought ….

    • I’m seeing them on Amazon but I’m not real sure they will actually appear….Going out and scouting for them is exactly what His Excellency is telling me not to do…..Now that this has been discussed, what few were there yesterday are long gone this morning. This is why they can’t order this….

  9. What about those ones that most of us have in the garage for grass cutting and woodworking?

  10. I found an old package with one in my workshop. That’s one good thing about being a rockhound and lapidary–you had N95 masks around for use when polishing stone.
