Most fully-vaccinated Americans can finally stop wearing their masks almost anywhere - indoors or outdoors, the CDC announced on Thursday. The new guidance still calls for wearing masks in crowded indoor settings like buses, planes, hospitals, prisons and homeless shelters, but could ease restrictions for reopening workplaces and schools. It will also no longer recommend that fully vaccinated people wear masks outdoors in crowds. CDC's announcement comes as the agency and the Biden administration have faced pressure to ease restrictions on fully vaccinated people - people who are two weeks past their last required COVID-19 vaccine dose - in part to highlight the benefits of getting the shot. In a seemingly prescient moment, Speaker Nancy Pelosi removed her mask in public for the first time in months on Thursday during her weekly Capitol Hill press conference. She took off her face covering once she got to the podium, and cited new House rules that require all members to wear masks on the floor - unless they are speaking. The CDC's expected easing of guidance also comes two weeks after the agency recommended that fully vaccinated people continue to wear masks indoors in all settings and outdoors in large crowds. In that update, the CDC also exaggerated the risk of Covid transmission outdoors as accounting for less than 10 percent of cases when the figure is likely less than one percent, experts say. That's sown distrust and confusion, fueling claims that the CDC has been keeping mask guidelines in places longer than it needs to. Things came to a head earlier this week, as Republican lawmakers grilled CDC Director Dr Rochelle Walensky over masking guidelines, claiming that the agency had let them drag on too long. To-date, more than 117 million fully vaccinated Americans are still advised to wear their masks anytime they are inside (besides at home) and in crowded places outdoors.

CDC Says Double-Masking Offers More Protection Against The Coronavirus

As new, more transmissible variants of the coronavirus spread, the CDC says wearing a cloth mask over a surgical mask offers increased protection against the virus.

The Centers for Disease Control and Prevention released new research on Wednesday that found wearing a cloth mask over a surgical mask offers more protection against the coronavirus, as does tying knots on the ear loops of surgical masks. Those findings prompted new guidance on how to improve mask fit at a time of concern over fast-spreading variants of the virus.

For optimal protection, the CDC says to make sure the mask fits snugly against your face and to choose a mask with at least two layers.

The Centers for Disease Control and Prevention released new research on Wednesday that found wearing a cloth mask over a medical mask is one way to reduce exposure to aerosol droplets that can transmit the coronavirus.

Centers for Disease Control and Prevention

In laboratory testing, researchers simulated coughs and breathing and tested how well different masks worked to block aerosol particles — comparing no mask, a cloth mask or a surgical mask. They also tested two methods to optimize the fit of cloth and medical masks: wearing a cloth mask over a surgical mask, and tying knots on the ear loops of surgical masks and then tucking in and flattening the extra material against the face.

Both methods produced substantially improved protection against transmission of and exposure to infectious aerosols.

"In the study, wearing any type of mask performed significantly better than not wearing a mask," said CDC Director Rochelle Walensky in a briefing from the White House COVID-19 Response Team on Wednesday.

"And well-fitting masks provided the greatest performance at both blocking emitted aerosols and exposure of aerosols to the receiver. In the breathing experiment, having both the source and the receiver wear masks modified to fit better reduced the receiver's exposure by more than 95%, compared to no mask at all," she said.

The CDC compared the protection offered by (from left) an unknotted medical procedure mask, a cloth mask covering medical procedure mask, and medical procedure mask that is knotted and tucked.

Centers for Disease Control and Prevention

Walensky said the laboratory findings underscore the importance of wearing a mask correctly and ensuring it fits snugly over your nose and mouth. The new information does not alter the CDC's guidance on who should wear a mask and when.

As of Feb. 2, masks are now required on planes, buses, trains and other public transportation traveling into, within or out of the U.S., as well as in U.S. transit hubs such as airports and stations.

The CDC's guidance on improving mask fit now recommends:

  • Choosing a mask with a nose wire, which prevents air from leaking out along the top
  • Using a mask fitter or brace over a disposable or cloth mask, to prevent air from leaking out. These small, reusable devices cinch a cloth or medical mask to create a tighter fit and improve mask performance, Walensky said.
  • Make sure your mask fits snugly over your nose, mouth and chin: "If the mask has a good fit, you will feel warm air come through the front of the mask and may be able to see the mask material move in and out with each breath," the CDC says.
  • Add layers of material – either by using cloth mask with multiple layers of fabric or by wearing a disposable mask under a cloth mask.

But double-masking isn't recommended for all masks. Don't combine two disposable masks, the CDC says: "Disposable masks are not designed to fit tightly and wearing more than one will not improve fit."

And don't layer another mask on top of a KN95, either. That mask should be used alone, the CDC says.

When the Mask You’re Wearing feels Unmasculine

Demonstrators protesting against coronavirus restrictions last week in Swampscott, Mass.

The Covid-19 pandemic has divided Americans into two camps. To no one’s surprise, lockdown politics have joined the legion of issues that pit Democrats against Republicans.
Take Daniel Horowitz, senior editor of Conservative Voice.

Objecting to the lack of attention that has been paid to what he considers the relatively light impact of the coronavirus on nonurban — largely white — areas of the country, Horowitz writes: “We now know that geography played a large role. 54 percent of all U.S. deaths were in the 100 counties in or within 100 miles of NYC.”

Covid-19 deaths — more than 90,000 so far — are “concentrated among the elderly,” Horowitz continues, and the “virus lopsidedly targets people with particular underlying conditions, such as heart disease and diabetes.”
The death rate, Horowitz claims, “doesn’t even climb above 1% until you reach over 70, with a steep and dangerous growth of risk over 75 and 80.”

To deal with a threat Horowitz sees as focused on “specific” groups, he writes,
We destroyed our entire country and sacked the Constitution all for a very narrow and specific problem that required a precise and balanced approach.
From the other end of the ideological spectrum, Laura McGann, editorial director of Vox.com, wrote, in an article posted on April 22,
We do know that gatherings spread the virus. Again and again, when groups get together, attendees get sick. Some have died. And we don’t know the extent to which they’ve spread it to others, though we know it’s a terribly contagious virus.
Don’t “be fooled by Fox News, Donald Trump, or the same type of groups that produced the Tea Party a decade ago,” McGann warned.
A protester holds a sign reading “Give me liberty or give me Covid-19” while another sign reads “#End the shutdown.”“In 21st century American politics, truth is tribal.”

WASHINGTON POST

In other nations, there is no such divide. In many Asian countries, surgical masks were socially acceptable long before the coronavirus pandemic, partly as a result of experience in past pandemics, like SARS in 2003.
“In Hong Kong, it is pretty common, even without an outbreak, to see people going around in masks because they may be sick and they don’t want to infect other people,” Keiji Fukuda, head of the University of Hong Kong’s School of Public Health, told Today’s WorldView in March
A spate of studies released this summer supported mask-wearing. One review funded by the World Health Organization and published in the Lancet journal looked at data from 172 observational studies and concluded that wearing face masks reduced the risk of coronavirus infection.
For many, this was all the evidence needed. Other policies for controlling the spread of the virus are enormously costly and practically difficult, from shutting down schools and offices to setting up complicated contact tracing. A mask, on the other hand, is cheap and has little downside.


THOMAS EDSALL, NY TIMES
This partisan fight over the lockdown has shown us, once again, how differently the choices government leaders make look to different constituencies of our society. Whether you emphasize the imperative to save lives or the consequences of economic devastation, with more than 46 million unemployed as of June 24, determines what you think the proper response to the outbreak should be, to a degree that is astonishing even in our deeply polarized society.

In a matter of three weeks, Republican voters shifted from a modest majority (51-48) concerned that the restrictions would be lifted too quickly, to a similarly modest majority (53-47) concerned that the restrictions will not be lifted quickly enough. Democrats, on the contrary, went from a decisive majority who feared (81-18) that restrictions would be lifted too quickly to an even stronger concern (87-13).
Robert Griffin, research director of the nonpartisan Democracy Fund Voter Study Group, provided The Times with demographic data from a May 7-13 survey describing voters who oppose lockdown policies. They are decisively Republican (at 55 percent) compared with 27 percent Democratic and 17 percent independent; majority male, at 58 percent; largely white (69 percent compared with 7 percent black and 17 percent Hispanic); and less well educated, 74 percent without college degrees, 24 percent with degrees.

What are some of the forces driving the split between those who prioritize the economy and those whose primary concern is the physical health of the population?
W. Bradford Wilcox, a sociologist at the University of Virginia, emailed in response to my inquiry:
Progressives have grown more likely to embrace a culture of “safetyism” in recent years. This safetyism seeks to protect them and those who are deemed the most vulnerable members of our society from threats to their emotional and physical well-being.
In the case of Covid-19, he continued,
progressives are willing to embrace the maximal measures to protect themselves, the public, and the most vulnerable among us from this threat.
In contrast, according to Wilcox,
many conservatives are most concerned about protecting the American way of life, a way of life they see as integrally bound up with liberty and the free market.

Because many on the political right see the lockdowns as impinging “on their liberty, the free market’s workings, and their financial well-being,” he continued, “many conservatives want the lockdowns ended as quickly as possible.”

In addition, Wilcox noted, “some (especially male) conservatives see the lockdowns and mask wearing as expressions of cowardice that they reject as unmanly.”
This last point touches on “the white male effect,” a theme that regularly emerges in studies of risk taking and risk aversion.

express significantly less personal worry about the quality of the environment and about eight environmental problems than do other adults in the general public, even controlling for the effects of several relevant social, demographic, political, and temporal variables.
In a separate 2011 paper, “Cool dudes: The denial of climate change among conservative white males in the United States,” McCright and Dunlap found that the most intense rejection of climate change was found not just among conservative white men, but that opposition was “even greater for those conservative white males who self-report understanding global warming very well.”
They found, for example, that 71.6 percent of white males conservatives who claim to understand global warming very well agreed that “recent temperature increases are not primarily due to human activities.” Among all conservative white men, the percentage in agreement fell to 58.5. Among everyone else, the percentage dropped to 31.5.

All of which brings to mind President Trump’s assessment of his own ability to understand the health issues surrounding the pandemic: “I like this stuff. I really get it,” he declared during a tour of the Centers for Disease Control and Prevention in Atlanta on March 6. “People are surprised that I understand it. Every one of these doctors said ‘How do you know so much about this?’”



The McCright and Dunlap papers were written years before the current pandemic, but their analysis is directly relevant to the present. McCright emailed in response to my queries:
If you are a conservative, a key tenet of your ideology is that unregulated markets naturally produce good; they are the most efficient way that humans have ever seen for distributing goods, services, wealth, etc. Any attempts to regulate, intervene upon, steer, etc. an economic market will make it necessarily less efficient. A government driven by some sense of altruism — ‘dogooderism’ by ‘bleeding hearts’ — will only muck up the functioning of an efficient market.
Liberals, McCright continued,
do not hold nearly as much belief in the power of unregulated markets to necessarily produce good without substantial negative side effects. As such, liberals are more supportive of governmental intervention to protect public health, environmental quality, the poor, etc. In other words, liberals accept some degree of economic regulation, and perhaps slower growth, reduced profits, etc., if it means improving public health, environmental quality, etc.
I asked: Do liberals and conservatives value life in different ways? McCright replied, “Liberals and conservatives certainly value different things — and ‘life’ gets caught up in these different things in different ways.”
In general, he contended,
conservatives value economic growth; markets with little or no governmental intervention; little to no constraints on ‘individual liberty’ and private property rights; etc. Liberals value educational opportunities; support for the vulnerable; environmental protection; checks on economic power; the extension of rights to previously oppressed groups; etc.
In a separate email, Dunlap wrote that there was a clear link between “climate change denial and the mixed reaction to Covid19.”
Dunlap argued that “with the rise of ‘right-wing’ populism,” conservatives and Republicans have developed
a strong hostility toward expertise in general, as obvious in the Trump Administration. Both of these strands build upon a tradition of anti-intellectualism in the U.S., but have taken it to far greater lengths than ever before. We see this in the current dismissal of scientific evidence and expertise in dealing with Covid-19, and more recent outright attacks on the experts — because experts do not play along with the charade that the coronavirus does not represent a serious threat.
The “white male effect,” in turn, interacts with differing responses of men and women to the pandemic.
Peter Ditto, a psychologist at the University of California-Irvine, wrote me that
there is good evidence of sex differences in responses to the coronavirus; women are more likely to report favoring and practicing social distance measures than are men.
This, in turn, fits with “the general sense that liberals are the more ‘feminine’ of the two parties,” Ditto argues, which results in the following pattern:
While liberals adopt their nurturant role, bemoaning the climbing infection and death rates and are willing to accept economic carnage in favor of minimizing the loss of human life, conservatives are more likely to, in effect, tell the American people to “walk it off,” increasingly staking out the position that some loss of life must be endured for the greater economic good.
In addition, in Ditto’s view, there is a fundamental tension arising “from how the two sides view the value and integrity of scientists.” Conservatives, Ditto wrote, are
more likely to question conclusions of scientists because they are more likely to question their motives — seeing them as typical liberal pansies who just can’t accept the reality that people die. At the extreme, hard right conservative thinking manifests in conspiracy theories painting Fauci, the CDC and the WHO as malevolent agents whose hidden agendas having nothing to do with saving American lives.
In analyses of partisan divergence in response to the pandemic, two different outcomes emerge.
An extensive 2017 examination of research on threats, “The politics of fear: Is there an ideological asymmetry in existential motivation?,” by John JostChadly SternNicholas O. Rule and Joanna Sterling, of N.Y.U., the University of Illinois, the University of Toronto and Princeton, found, for example, that:
Exposure to objectively threatening circumstances, such as terrorist attacks, was associated with a “conservative shift” at individual and aggregate levels of analysis. Psychological reactions to fear and threat thus convey a small-to-moderate political advantage for conservative leaders, parties, policies, and ideas.
So far, however, the threat posed by the pandemic has not produced a shift to the right.
The current level of support for Joe Biden as Nathaniel Rakich of 538 writes, suggests that there might yet be “a Democratic wave of truly epic proportions,” although Rakich is quick to caution that “it’s hard to know at this point if these polls indicators of an overwhelming Democratic electoral environment.”

Recent work shows that voters tend to move in either a conservative or liberal direction depending on the specific source of the threat.

A 2018 paper, “Can Threat Increase Support for Liberalism? ” by Fade Eadeh, of Carnegie Mellon, and Katharine K. Chang, of the National Institute of Mental Health, reported that some threats push voters to the right, while others push the electorate to the left. Threats to health are among those that push the electorate to the left.

The authors argue that a health care threat of the kind the country now faces, along with threats of pollution and corporate corruption, produce “increased support for components of liberalism.”
The critical factor determining whether voters respond to threat by turning left or right, according to Eadeh and Chang, is the partisan “ownership” of the issue and which side “is best seen as ‘fixing’ that threat.”
In the United States, they write:
conservative parties (i.e., Republicans) are perceived as more effective dealing with terrorism, whereas liberal parties (Democrats) are perceived as better at handling health care and environmental issues.

The opposition among conservative Republicans to the lockdown — designed to protect American from contact with the coronavirus — presents an interesting corollary to the moral foundations theory developed by Jonathan Haidt of N.Y.U. and Jesse Graham of the University of Utah. In essence, the theory posits that conservatives are more preoccupied with notions of purity and disgust than liberals.

In an email, Ditto has deftly summarized the work of Haidt et al:
From the perspective of moral foundations theory, conservatives’ greater concern for purity and fear of contamination would suggest that they would respond more vigorously to a virus than would liberals. This was indeed the case with the Ebola crisis during the Obama Administration when conservative voices often expressed extreme concern about and even fear of Ebola spreading in the United States, while roundly criticizing President Obama’s more measured reaction.

Haidt, Graham and colleagues have deployed a “scale” to measure preoccupation with disgust. The battery includes 27 questions, for example, “how true about you is: ‘I might be willing to try eating monkey meat, under some circumstances’ or ‘I never let any part of my body touch the toilet seat in public restrooms,’ ” Other questions ask respondents to rank “How disgusting would you find the following experiences,” including “while you are walking through a tunnel under a railroad track, you smell urine” or “You discover that a friend of yours changes underwear only once a week.”
The Graham-Haidt study suggests that conservatives would show a higher level of fear of the pandemic and a readiness to comply with restrictions on interpersonal contact.

A group of four California-based scholars is exploring why this is not the case.
In an intriguing ongoing study, Colin Holbrook, a professor of cognitive science at the University of California-Merced, and Daniel M. T. FesslerTheodore Samore and Adam Sparks, all of the anthropology department at U.C.L.A., find a sharp split in the behavior of conservative Democrats and conservative Republicans.

Holbrook wrote by email that he and his colleagues
assessed disgust sensitivity and found conservatism in our present sample predicted greater disgust-proneness. The emotion of disgust functions to curtail disease-transmission, suggesting that conservatives should, all else equal, be likely to take greater disease precautions.
They then “measured precautionary behaviors, such as hand-washing, mask-wearing, social distancing, seeking cleaning supplies, etc.” and found that conservatism, measured in a number of distinct ways, positively and highly significantly predicts precautionary behaviors among the Democrats in our sample, but not among the Republicans.

Holbrook wrote that this apparent contradiction grows out of the responsiveness of the conservative Republicans
to authority messaging, from the president as well as other conservative political and media figures. There are theoretical reasons to expect that, had conservative authority figures encouraged them to do so, conservative Republicans would be as likely — perhaps even more likely — as conservative Democrats to engage in precautionary behaviors.
Put another way, loyalty to Trump and others on the right was more powerful than the strong inclination among these Republican voters to take steps to insulate themselves from the threat of the coronavirus.

Jesse Graham, in an email, wrote that “when people ask me the question ‘if conservatives are more concerned with purity, why are red states being so slow to act against a viral contagion?’” he replies:
I don’t think these political differences are due to any underlying values differences between liberals and conservatives. I think it’s due to the almost immediate politicization of the threat, with Trump and Fox News downplaying the seriousness of Covid-19, and ‘left-leaning’ reality-based sources issuing the more dire warnings.
The pandemic has become another example of Trump’s mastery over his most loyal subjects, his ability to manipulate them into violating their own instincts. It is this power over a substantial bloc of the electorate that has put him in the White House — and continues to make him so dangerous.

The battle over masks in a pandemic: An all-American story




WASHINGTON POST

Max Parsell hasn't been wearing a mask during the coronavirus pandemic and doesn't intend to start. It's a matter of principle.“Making individual decisions is the American way,” Parsell, a 29-year-old lineman for a power company, said as he picked up his lunch at a barbecue joint at a rural crossroads south of Jacksonville. “I’ll social distance from you if you want, but I don’t want the government telling me I have to wear a mask.”



Parsell need not worry: Gov. Ron DeSantis (R) has not made mask-wearing mandatory here in Florida. That’s in sharp contrast with what’s happening more than 2,000 miles away in California, where Gov. Gavin Newsom (D) on Thursday reacted to rising ­caseloads by making ­mask-wearing mandatory.


In this sprawling, heterogeneous country, the pandemic has become yet another thing on which Americans are divided. Mask-wearing for some people is an identifier of broader beliefs and political leanings. Like so many issues rooted in science and medicine, the pandemic is now fully entangled with ideological tribalism. This has played out before: helmets for motorcyclists, seat belts in cars, smoking bans in restaurants. All of those measures provoked battles over personal liberty.
“I don’t like to see people out in bars congregating without masks right now,” Dr. Anthony Fauci said in an interview, but he added, “We may have mayors and may have governors who are saying the right thing, but because of the individual spirit of our country, we don’t listen to authority. You go to Korea, you go to Japan, when the authorities say something, man, it gets done.” The independent American trait can complicate public health measures, he acknowledged. "When you’re dealing with infectious diseases, a small percentage of people who don’t comply can have an impact on the entire population,” he said.
The United States has far more coronavirus infections than any other country. It has the most covid-19 deaths.
In Wisconsin, the Republican state legislature successfully sued to strike down Democratic Gov. Tony Evers’s stay-at-home order, which many local leaders declared they would ignore. And in several states with Republican governors, including Arizona, Arkansas and Oklahoma, Democratic mayors have expressed frustration with a lack of aggressive action to halt the viral spread.
In Orange County, Calif., the board of supervisors said it would no longer enforce mask mandates locally, going against the wishes of health department officials. In Nebraska, Gov. Pete Ricketts (R) told local authorities in his state not to mandate masks in municipal buildings — unless they wanted to lose out on their allocation of money from the federal Cares Act.
AMC, the sprawling movie house chain, made a proclamation of its own earlier in the week, declaring it would not mandate masks so as “not to be drawn into political controversy” — thereby drawing itself into political controversy anyway. But by Friday, reflecting the fluid nature of the pandemic and the decisions enveloping it, AMC had reversed course, announcing that it would insist on mask-wearing after all.
Compared with most countries, the United States has been quick to reopen, according to researchers at the Oxford University Blavatnik School of Government who have crafted a Stringency Index that tracks government shutdown orders and other interventions. But multiple states, particularly in the South, Midwest and Southwest, are experiencing spikes in infections.
Adding to that confusion is the fact that successful public health measures, including shutdowns and mandates to wear masks, can appear to be unnecessary. There is no easy way to calculate what might have happened if the measures hadn’t been imposed.
Memorial Day weekend facilitated an explosion of self-determination, as pictures of packed pools and overflowing clubs — all enjoyed by people bereft of masks — left public health officials wringing their hands. Pictures of crowds packed into a pool at Backwater Jack’s, a beloved local spot at Lake of the Ozarks in Missouri, drew national attention.
So far, health officials in the state say they do not think the gathering resulted in the catastrophic spread of the coronavirus that some predicted. 
 Since Memorial Day, at least 10 states have seen covid-19 hospitalizations rise at least 10 percent, according to a Post analysis of data.
Not all states report covid-19 hospitalizations, so the list may be longer. Florida, for example, is experiencing an explosion in cases but does not report hospitalization data.
In Arizona, Gov. Doug Ducey (R) succumbed to pressure from local leaders and revised an executive order that had barred city leaders from instituting their own policies on face coverings.
Within 48 hours of Ducey’s reversal, Phoenix Mayor Kate Gallego (D) had announced a mask mandate would be on the next city council agenda. Tucson Mayor Regina Romero (D) announced an executive order mandating masks in her city, too.
Montgomery, Ala., has emerged as a virus hot spot in recent weeks, with cases increasing 73 percent in the surrounding county during June. Hospitals in the region are experiencing a strain on intensive care units and other resources. But when the city council voted on a measure that would have mandated masks in public among groups of 25 or more, the measure failed.
A day later, Montgomery Mayor Steven Reed (D) announced he would sign an executive order mandating masks in public anyway.
