Story at a glance

• According to the World Health Organization's June 5, 2020, guidance on face mask use, there's no direct evidence that universal masking of healthy people is an effective intervention against respiratory illnesses
• While masks do not prevent the spread of viral infections, the WHO still makes a case for universal mask-wearing, citing benefits such as reduced stigmatization of people caring for COVID-19 patients in nonclinical settings, making people feel like they're doing something to help, serving as a reminder to be compliant with other measures, and economic benefits for people who can sew homemade masks
• Despite the fact that cloth masks are far less effective for blocking potentially infectious respiratory droplets, the WHO recommends cloth masks should be worn by infected persons in community settings
• A policy review paper published in the CDC's journal Emerging Infectious Diseases found that masks did not protect against influenza in non-healthcare settings
• Harms and risks of mask-wearing include health effects associated with poor air quality and toxic ingredients in the mask, self-contamination caused by manipulation of the mask by contaminated hands, general discomfort, facial skin lesions, irritant dermatitis or worsening acne, and a false sense of security that may reduce adherence to other preventive measures such as hand hygiene

According to the director general of the World Health Organization, Tedros Adhanom Ghebreyesus, life will not be returning to your old normal anytime soon.

What's more, things will only get worse unless the public follow health advice such as wearing masks and social distancing.

The somber announcement came during a July 13, 2020, press conference: https://youtu.be/4RV4ht-SG14

This, despite the fact that the WHO's June 5, 2020, guidance memo¹ on face mask use states there's no direct evidence that universal masking of healthy people is an effective intervention against respiratory illnesses.

What's more, people are being urged to use cloth masks or bandanas (ostensibly to prevent shortages among health care staff), none of which conform to any kind of quality standards, and according to what little scientific evidence is available have been shown to provide only about half of what little protection you may get from a surgical mask.

No Direct Evidence to Support Universal Mask Usage

SARS-CoV-2 is a beta-coronavirus with a diameter between 60 nanometers (nm) and 140 nm, or 0.06 to 0.14 microns (micrometers)².

This is about half the size of most viruses, which tend to measure between 0.02 microns to 0.3 microns³.

Virus-laden saliva or respiratory droplets expelled when talking or coughing measure between 5 and 10 microns⁴, and it is these droplets that surgical masks and respirators can block.

For example, N95 masks can filter particles as small as 0.3 microns⁵, so they may prevent a majority of respiratory droplets from escaping.

They cannot block aerosolized viruses, however, that are in the air itself. Additionally, many N95 masks only protect the wearer, as they have exhalation ports that allow you to exhale unfiltered air.

Lab testing⁶ has shown 3M surgical masks can block up to 75% of particles measuring between 0.02 microns and 1 micron, while cloth masks block between 30% and 60% of respiratory particles of this size.

As noted in the WHO's guidance memo⁷:

Curiously, while cloth masks and face coverings are far less effective for blocking respiratory droplets, the WHO recommends that cloth or nonmedical masks,

CDC Policy Review Found No Evidence of Usefulness Either

A policy review paper⁹ published in Emerging Infectious Diseases in May 2020 - the Center for Disease Control and Prevention's own journal - has also reviewed,

Pages 970 to 972 of the review include the following quotes¹⁰:

These Mistakes Undermine the Protection Masks May Provide

If and when you do use a mask, you have to follow proper protocols, or else you can nullify what little protection they do offer against potentially infectious respiratory droplets.

As detailed in WHO's guidance memo, you need to make sure your medical mask is¹¹:

• Changed when wet, soiled or damaged
• Untouched. Do not adjust or displace it from your face for any reason. "If this happens, the mask should be safely removed and replaced; and hand hygiene performed"
• Discarded and changed after caring for any patient on contact/droplet precautions for other pathogens

The memo also points out that,

Now, if administrative hospital staff do not need to wear masks,

Broward county, Florida, has gone so far as to issue an emergency order¹² mandating masks to be worn inside your own residence.

But,

In summary, it is likely that masks are not entirely useless in all circumstances.

However, the literature rather strongly suggests the usefulness of masks depends on a significant number of factors - type, fit, length of use, purpose and circumstances - which are effectively impossible to account for in public universal-masking policies.

The science, contrary to the ignorant platitudes we are bombarded with, has NOT proven that universal masking is effective for viral containment, and has instead provided substantial grounds for skepticism of such a policy.

Benefits of Mask Wearing Do Not Include Infection Control

Despite the lack of scientific evidence showing masks do much of anything to prevent the spread of viral infections, the WHO still manages to make a case for universal mask wearing.

The "potential benefits" listed, however, have little to do with health, and much more to do with learning submission.

According to the WHO, potential benefits of mask wearing include¹³:

• "Reduced potential stigmatization of individuals wearing masks to prevent infecting others or of people caring for COVID-19 patients in nonclinical settings" - In other words, we should all wear masks to make people caring for COVID-19 patients feel more accepted, as if that's actually a significant problem.
• "Making people feel they can play a role in contributing to stopping spread of the virus" - I.e., masks, while providing a false sense of security, make people feel like they're "doing something" to help. Put another way, it makes people feel virtuous and "good."
• "Reminding people to be compliant with other measures" - In other words, mask wearing is a sign of overall compliance.
• "Potential social and economic benefits" - This is perhaps the most ludicrously strained reason of all.

According to the WHO:

Potential Harms and Risks of Mask Wearing

The WHO also lists a number of potential harms and risks of mask wearing, which,

These include¹⁴:

• Self-contamination due to the manipulation of the mask by contaminated hands or not changing the mask when wet, soiled or damaged
• General discomfort, as well as facial skin lesions, irritant dermatitis or worsening acne
• False sense of security that may reduce adherence to other well recognized preventive measures such as hand hygiene
• Disadvantages for or difficulty wearing them by specific vulnerable populations such as those with mental health disorders, developmental disabilities, the deaf and hard of hearing community, and children
• Difficulty wearing them in hot and humid environments

Aside from these, several people have demonstrated that masks can rapidly result in the buildup of toxic carbon dioxide, which can have a markedly detrimental impact on health.

In one video, a science teacher tried to evade YouTube censorship by saying children should wear face masks to school - all while holding up handwritten signs informing viewers the tactic was for censorship evasion, and to pay attention to the carbon dioxide metering results, which show carbon dioxide levels behind the mask shoot up above 10,000 parts per million (ppm) after just 10 breaths.

After garnering several hundred thousand views, the video was removed for "violating YouTube community guidelines."

Del Bigtree of The Highwire has performed an identical demonstration¹⁵ (see bitchute video below). With an N95 mask on, the carbon dioxide level spikes above 8,480 ppm within seconds.

Above 5,000 ppm, OSHA warns that "toxicity or oxygen deprivation could occur."

Mask Test Proves Toxic For Children (video)

Carbon dioxide levels between 2,000 ppm and 5,000 ppm are associated with headaches, sleepiness, poor concentration, loss of attention, increased heart rate and slight nausea.

The maximum permissible daily exposure limit is 5,000 ppm.

Wearing a standard surgical mask, carbon dioxide levels again reached above 8,000 ppm, although it took longer. Shockingly, wearing a cloth bandana resulted in carbon dioxide buildup near the nose and mouth exceeding 8,000 ppm.

Even wearing a clear plastic face shield (without a mask) resulted in carbon dioxide levels in the 1,500-ppm range, which is associated with drowsiness and poor air quality.

The video at the top of this section also addresses many of the potential harms and risks of masks wearing.

Toxic ingredients that can worsen breathing problems are yet another potential hazard of certain masks. For example, surgical masks are made of plastics like polypropylene, a known asthma trigger¹⁶.

The 2018 study, ¹⁷,¹⁸ "Hypoxia Downregulates Protein S Expression," also describes how hypoxia (low oxygen concentration) increases your risk of blood clots by reducing protein S, which is a natural anticoagulant.

Wearing a mask, especially for long periods of time, may reduce your oxygen concentration, and considering COVID-19 is already associated with abnormal blood clotting, inducing hypoxia may be ill advised.

PPE Waste Is Becoming an Environmental Hazard

Last but not least, environmentalists are now warning that personal protective equipment (PPE) such as medical face masks may turn into a devastating environmental problem.

As reported by The Guardian, June 8, 2020¹⁹:

Consider Peaceful Civil Disobedience

Clearly, most people are being bombarded with mainstream media propaganda that seeks to convince you that masks are necessary to prevent the spread of COVID-19.

So, it is entirely understandable that you would want everyone to wear masks because you believe they will save lives.

However, if you carefully evaluate the evidence, independent of the mainstream narrative, it is likely you will conclude that this recommendation has nothing to do with decreasing the spread of the virus but more to indoctrinate you into submission.

Most objections to mask-wearing requirements are not to the masks themselves, but to the mandate, and well-documented consequences such as oxygen deprivation should give anybody pause when considering a legal requirement of wearing masks in public.

We already see that most people wear masks in public regardless of mandates²⁰.

But it is entirely irresponsible and unethical for governments to mandate such a practice on anybody.
