Should you wear a mask on a plane, bus or train when there’s no mandate? 4 essential reads to help you decide

Despite the halt to the federal mask mandate for mass transit, people may still choose to protect themselves. For those who do, the type of mask and how…

On April 18, 2022, a judge in Florida struck down the federal mandate requiring passengers on mass transit to wear masks. While the U.S. Centers for Disease Control and Prevention still recommends that passengers mask up while on planes, trains or buses, it is no longer a requirement. When asked whether people should wear masks on planes, President Joe Biden replied: “That’s up to them.”

The Conversation has been covering the science of masks since the beginning of the pandemic. Masking may no longer be required on mass transit, but you can always choose to still wear a mask. For those worried about being exposed to SARS-CoV-2 or developing COVID-19, below are highlights from four articles exploring the benefits of wearing a mask and how to get the most protection from wearing one.

1. Masks can protect the person wearing them

A lot of the reason for wearing a mask is to protect others. But early on in the pandemic, Monica Gandhi, a professor of medicine at the University of California, San Francisco, explained how masks can protect the wearer, too.

“When you wear a mask – even a cloth mask – you typically are exposed to a lower dose of the coronavirus than if you didn’t,” Gandhi writes. “Both recent experiments in animal models using coronavirus and nearly a hundred years of viral research show that lower viral doses usually mean less severe disease.

Though it’s only one of many factors, “the amount of virus that you’re exposed to – called the viral inoculum, or dose – has a lot to do with how sick you get. If the exposure dose is very high, the immune response can become overwhelmed,” explains Gandhi. “On the other hand, if the initial dose of the virus is small, the immune system is able to contain the virus.”

The better the mask, the lower the exposure dose. And in the many months since Gandhi wrote that story, a lot of work has been done to determine which kinds of masks are most effective.

2. What makes for a good mask?

The first thing to consider when wearing a mask is whether it’s a good one. Christian L'Orange is a professor of mechanical engineering and has been testing different masks for the state of Colorado since the pandemic started. He explains that there are two things that make for a protective mask. “First, there’s the ability of the material to capture particles. The second factor is the fraction of inhaled or exhaled air leaking out from around the mask – essentially, how well a mask fits.”

When it comes to these two attributes, L'Orange says, “the N95 and KN95 masks are the best option.” This performance has a lot to do with the materials they are made from. “These fibers are very tightly packed together so the gaps a particle must navigate through are very small. This results in a high probability that particles will end up touching and sticking to a fiber as they pass through a mask. These polypropylene materials also often have a static charge that can help attract and catch particles.”

Fit is the second important factor for a mask. As L'Orange writes, “a mask can offer protection only if it doesn’t leak.” N95s and KN95s are stiff and seal much better than other masks.

If you don’t have access to an N95 or KN95, surgical masks should be your second choice. They are made of densely woven material, but they don’t seal perfectly. Cloth masks should be your last choice because of their generally loose weave and bad fit. But there are ways to improve the performance of surgical and cloth masks.

3. How to make a mask fit well

“No matter how good a mask’s material is, it won’t work well if it doesn’t fit well,” writes Scott Schiffres, a mechanical engineer at Binghamton University.

There are two ways to improve the fit and performance of surgical and cloth masks. The first, explains Schiffres, is simply wearing two masks. “Double-masking is wearing a cotton mask over a medical-procedure mask.” This can greatly improve the fit and add a little bit more filtration. The second approach is to knot and tuck a surgical mask so that it fits better.

Knotting and tucking a surgical mask can make it fit much better.

As Schiffres explains in his article, “Knotting and tucking entails tying a knot in the elastic loops that go over your ears, close to where they attach to the mask. Then, you tuck the extra mask fabric into the gap that is often present where the ear loops attach to the mask, and flatten that part as much as possible. Both of these tricks make a better fit and decrease the mask-wearers’ exposure to potentially infectious aerosols by 95% as compared with wearing no mask at all. That’s a 15% improvement over the 80% efficiency found when using a single surgical mask.

4. Breakthrough cases and new variants

The final consideration when deciding to wear a mask isn’t about you. Doing so can protect others.

Sara Sawyer, Arturo Barbachano-Guerrero and Cody Warren are virologists and biologists at the University of Colorado Boulder. In a recent story, they write that omicron "is often able to evade existing immunity long enough to start an infection, cause symptoms and transmit onward to the next person.” “This explains why reinfections and vaccine breakthrough infections seem to be more common with omicron.”

Case numbers are low for now, and therefore so is the risk of catching or transmitting the coronavirus. But it is not zero; some places have higher risk than others, and new variants can come on quickly. As the team writes, all new variants that spread widely – so-called variants of concern – are likely to be highly transmissible.

The person next to you on the plane might not be wearing a mask and, as it stands, that is their choice to make. If you want to lower your own chances of catching or spreading the coronavirus, there are still a number of reasons to wear a well-fitting, high-quality mask.

Are Voters Recoiling Against Disorder?

The headlines coming out of the Super Tuesday primaries have got it right. Barring cataclysmic changes, Donald Trump and Joe Biden will be the Republican and Democratic nominees for president in 2024.

With Nikki Haley’s withdrawal, there will be no more significantly contested primaries or caucuses—the earliest both parties’ races have been over since something like the current primary-dominated system was put in place in 1972.

The primary results have spotlighted some of both nominees’ weaknesses.

Donald Trump lost high-income, high-educated constituencies, including the entire metro area—aka the Swamp. Many but by no means all Haley votes there were cast by Biden Democrats. Mr. Trump can’t afford to lose too many of the others in target states like Pennsylvania and Michigan.

Majorities and large minorities of voters in overwhelmingly Latino counties in Texas’s Rio Grande Valley and some in Houston voted against Joe Biden, and even more against Senate nominee Rep. Colin Allred (D-Texas).

Returns from Hispanic precincts in New Hampshire and Massachusetts show the same thing. Mr. Biden can’t afford to lose too many Latino votes in target states like Arizona and Georgia.

When Mr. Trump rode down that escalator in 2015, commentators assumed he’d repel Latinos. Instead, Latino voters nationally, and especially the closest eyewitnesses of Biden’s open-border policy, have been trending heavily Republican.

High-income liberal Democrats may sport lawn signs proclaiming, “In this house, we believe ... no human is illegal.” The logical consequence of that belief is an open border. But modest-income folks in border counties know that flows of illegal immigrants result in disorder, disease, and crime.

There is plenty of impatience with increased disorder in election returns below the presidential level. Consider Los Angeles County, America’s largest county, with nearly 10 million people, more people than 40 of the 50 states. It voted 71 percent for Mr. Biden in 2020.

Current returns show county District Attorney George Gascon winning only 21 percent of the vote in the nonpartisan primary. He’ll apparently face Republican Nathan Hochman, a critic of his liberal policies, in November.

Gascon, elected after the May 2020 death of counterfeit-passing suspect George Floyd in Minneapolis, is one of many county prosecutors supported by billionaire George Soros. His policies include not charging juveniles as adults, not seeking higher penalties for gang membership or use of firearms, and bringing fewer misdemeanor cases.

The predictable result has been increased car thefts, burglaries, and personal robberies. Some 120 assistant district attorneys have left the office, and there’s a backlog of 10,000 unprosecuted cases.

More than a dozen other Soros-backed and similarly liberal prosecutors have faced strong opposition or have left office.

St. Louis prosecutor Kim Gardner resigned last May amid lawsuits seeking her removal, Milwaukee’s John Chisholm retired in January, and Baltimore’s Marilyn Mosby was defeated in July 2022 and convicted of perjury in September 2023. Last November, Loudoun County, Virginia, voters (62 percent Biden) ousted liberal Buta Biberaj, who declined to prosecute a transgender student for assault, and in June 2022 voters in San Francisco (85 percent Biden) recalled famed radical Chesa Boudin.

Similarly, this Tuesday, voters in San Francisco passed ballot measures strengthening police powers and requiring treatment of drug-addicted welfare recipients.

In retrospect, it appears the Floyd video, appearing after three months of COVID-19 confinement, sparked a frenzied, even crazed reaction, especially among the highly educated and articulate. One fatal incident was seen as proof that America’s “systemic racism” was worse than ever and that police forces should be defunded and perhaps abolished.

2020 was “the year America went crazy,” I wrote in January 2021, a year in which police funding was actually cut by Democrats in New York, Los Angeles, San Francisco, Seattle, and Denver. A year in which young New York Times (NYT) staffers claimed they were endangered by the publication of Sen. Tom Cotton’s (R-Ark.) opinion article advocating calling in military forces if necessary to stop rioting, as had been done in Detroit in 1967 and Los Angeles in 1992. A craven NYT publisher even fired the editorial page editor for running the article.

Evidence of visible and tangible discontent with increasing violence and its consequences—barren and locked shelves in Manhattan chain drugstores, skyrocketing carjackings in Washington, D.C.—is as unmistakable in polls and election results as it is in daily life in large metropolitan areas. Maybe 2024 will turn out to be the year even liberal America stopped acting crazy.

Chaos and disorder work against incumbents, as they did in 1968 when Democrats saw their party’s popular vote fall from 61 percent to 43 percent.

Veterans Affairs Kept COVID-19 Vaccine Mandate In Place Without Evidence

Authored by Zachary Stieber via The Epoch Times (emphasis ours),

The U.S. Department of Veterans Affairs (VA) reviewed no data when deciding in 2023 to keep its COVID-19 vaccine mandate in place.

VA Secretary Denis McDonough said on May 1, 2023, that the end of many other federal mandates “will not impact current policies at the Department of Veterans Affairs.”

He said the mandate was remaining for VA health care personnel “to ensure the safety of veterans and our colleagues.”

Mr. McDonough did not cite any studies or other data. A VA spokesperson declined to provide any data that was reviewed when deciding not to rescind the mandate. The Epoch Times submitted a Freedom of Information Act for “all documents outlining which data was relied upon when establishing the mandate when deciding to keep the mandate in place.”

The agency searched for such data and did not find any.

The VA does not even attempt to justify its policies with science, because it can’t,” Leslie Manookian, president and founder of the Health Freedom Defense Fund, told The Epoch Times.

“The VA just trusts that the process and cost of challenging its unfounded policies is so onerous, most people are dissuaded from even trying,” she added.

The VA’s mandate remains in place to this day.

The VA’s website claims that vaccines “help protect you from getting severe illness” and “offer good protection against most COVID-19 variants,” pointing in part to observational data from the U.S. Centers for Disease Control and Prevention (CDC) that estimate the vaccines provide poor protection against symptomatic infection and transient shielding against hospitalization.

There have also been increasing concerns among outside scientists about confirmed side effects like heart inflammation—the VA hid a safety signal it detected for the inflammation—and possible side effects such as tinnitus, which shift the benefit-risk calculus.

President Joe Biden imposed a slate of COVID-19 vaccine mandates in 2021. The VA was the first federal agency to implement a mandate.

President Biden rescinded the mandates in May 2023, citing a drop in COVID-19 cases and hospitalizations. His administration maintains the choice to require vaccines was the right one and saved lives.

“Our administration’s vaccination requirements helped ensure the safety of workers in critical workforces including those in the healthcare and education sectors, protecting themselves and the populations they serve, and strengthening their ability to provide services without disruptions to operations,” the White House said.

Some experts said requiring vaccination meant many younger people were forced to get a vaccine despite the risks potentially outweighing the benefits, leaving fewer doses for older adults.

By mandating the vaccines to younger people and those with natural immunity from having had COVID, older people in the U.S. and other countries did not have access to them, and many people might have died because of that,” Martin Kulldorff, a professor of medicine on leave from Harvard Medical School, told The Epoch Times previously.

The VA was one of just a handful of agencies to keep its mandate in place following the removal of many federal mandates.

“At this time, the vaccine requirement will remain in effect for VA health care personnel, including VA psychologists, pharmacists, social workers, nursing assistants, physical therapists, respiratory therapists, peer specialists, medical support assistants, engineers, housekeepers, and other clinical, administrative, and infrastructure support employees,” Mr. McDonough wrote to VA employees at the time.

This also includes VA volunteers and contractors. Effectively, this means that any Veterans Health Administration (VHA) employee, volunteer, or contractor who works in VHA facilities, visits VHA facilities, or provides direct care to those we serve will still be subject to the vaccine requirement at this time,” he said. “We continue to monitor and discuss this requirement, and we will provide more information about the vaccination requirements for VA health care employees soon. As always, we will process requests for vaccination exceptions in accordance with applicable laws, regulations, and policies.”

The version of the shots cleared in the fall of 2022, and available through the fall of 2023, did not have any clinical trial data supporting them.

A new version was approved in the fall of 2023 because there were indications that the shots not only offered temporary protection but also that the level of protection was lower than what was observed during earlier stages of the pandemic.

Ms. Manookian, whose group has challenged several of the federal mandates, said that the mandate “illustrates the dangers of the administrative state and how these federal agencies have become a law unto themselves.”

A new study indicates that problems with iron levels in the bloodstream likely trigger chronic inflammation and other conditions associated with the post-COVID phenomenon. The findings, published on March 1 in Nature Immunology, could offer new ways to treat or prevent the condition.

Long COVID Patients Have Low Iron Levels

Researchers at the University of Cambridge pinpointed low iron as a potential link to long-COVID symptoms thanks to a study they initiated shortly after the start of the pandemic. They recruited people who tested positive for the virus to provide blood samples for analysis over a year, which allowed the researchers to look for post-infection changes in the blood. The researchers looked at 214 samples and found that 45 percent of patients reported symptoms of long COVID that lasted between three and 10 months.

In analyzing the blood samples, the research team noticed that people experiencing long COVID had low iron levels, contributing to anemia and low red blood cell production, just two weeks after they were diagnosed with COVID-19. This was true for patients regardless of age, sex, or the initial severity of their infection.

According to one of the study co-authors, the removal of iron from the bloodstream is a natural process and defense mechanism of the body.

But it can jeopardize a person’s recovery.

When the body has an infection, it responds by removing iron from the bloodstream. This protects us from potentially lethal bacteria that capture the iron in the bloodstream and grow rapidly. It’s an evolutionary response that redistributes iron in the body, and the blood plasma becomes an iron desert,” University of Oxford professor Hal Drakesmith said in a press release. “However, if this goes on for a long time, there is less iron for red blood cells, so oxygen is transported less efficiently affecting metabolism and energy production, and for white blood cells, which need iron to work properly. The protective mechanism ends up becoming a problem.”

The research team believes that consistently low iron levels could explain why individuals with long COVID continue to experience fatigue and difficulty exercising. As such, the researchers suggested iron supplementation to help regulate and prevent the often debilitating symptoms associated with long COVID.

It isn’t necessarily the case that individuals don’t have enough iron in their body, it’s just that it’s trapped in the wrong place,” Aimee Hanson, a postdoctoral researcher at the University of Cambridge who worked on the study, said in the press release. “What we need is a way to remobilize the iron and pull it back into the bloodstream, where it becomes more useful to the red blood cells.”

The research team pointed out that iron supplementation isn’t always straightforward. Achieving the right level of iron varies from person to person. Too much iron can cause stomach issues, ranging from constipation, nausea, and abdominal pain to gastritis and gastric lesions.

1 in 5 Still Affected by Long COVID

COVID-19 has affected nearly 40 percent of Americans, with one in five of those still suffering from symptoms of long COVID, according to the U.S. Centers for Disease Control and Prevention (CDC). Long COVID is marked by health issues that continue at least four weeks after an individual was initially diagnosed with COVID-19. Symptoms can last for days, weeks, months, or years and may include fatigue, cough or chest pain, headache, brain fog, depression or anxiety, digestive issues, and joint or muscle pain.
