No Direct Evidence Masks Prevent Viral Infection
by Dr. Joseph Mercola
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

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

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).
This is about half the size of most viruses, which tend to measure
between 0.02 microns to 0.3 microns. 3
Virus-laden saliva or respiratory droplets expelled when talking or
coughing measure between 5 and 10 microns, 4 and it is these droplets
that surgical masks and respirators can block.
At present, there is no direct evidence
(from studies on COVID- 19
and in healthy people in the community)
on the effectiveness of

infection with respiratory viruses,
N95 masks can filter particles as small as 0.3
microns, 5 so they may prevent a majority of respiratory droplets
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
Lab testing 6 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
As noted in the WHO's guidance memo:
systematic literature reviews have reported that the use of N95
respirators compared with the use of medical masks is not
associated with any statistically significant lower risk of the
clinical respiratory illness outcomes or laboratory-confirmed
influenza or viral infections...
The use of cloth masks
(referred to as fabric masks in this document) as an alternative
to medical masks is not considered appropriate for protection of
health workers based on limited available evidence...
At present, there is no direct evidence (from studies on COVID-19
and in healthy people in the community) on the effectiveness of
universal masking of healthy people in the community to prevent
infection with respiratory viruses, including COVID-19."
Curiously, while cloth masks and face coverings are far less
effective for blocking respiratory droplets, the WHO recommends that
cloth or nonmedical masks,
"should only be
considered for source control (used by infected persons) in
community settings and not for prevention." 8
CDC Policy Review Found No Evidence of Usefulness Either
A policy review paper 9 published in Emerging Infectious Diseases in
May 2020 - the Center for Disease Control and Prevention's own
journal - has also reviewed,
"the evidence base on the effectiveness
of non-pharmaceutical personal protective measures... in
non-healthcare settings," and they too found no evidence of benefit:
"Although mechanistic studies support the potential effect of hand
hygiene or face masks, evidence from 14 randomized controlled trials
of these measures did not support a substantial effect on
transmission of laboratory-confirmed influenza."
Pages 970 to 972 of the review include the following quotes:
"In our systematic review, we identified 10 RCTs
controlled trials) that reported estimates of the effectiveness of
face masks in reducing laboratory-confirmed influenza virus
infections in the community from literature published during
1946 - July 27, 2018.
In pooled analysis,
we found no significant reduction in influenza transmission with
the use of face masks...
Disposable medical masks (also
known as surgical masks) are loose-fitting devices that were
designed to be worn by medical personnel to protect accidental
contamination of patient wounds, and to protect the wearer
against splashes or sprays of bodily fluids...
There is limited evidence for their effectiveness in preventing
influenza virus transmission either when worn by the infected person
for source control or when worn by uninfected persons to reduce

In this review, we
did not find evidence to support a protective effect of personal
protective measures or environmental measures in reducing influenza
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 is: 11
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,
"Staff who do not work in clinical
areas do not need to use a medical mask during routine activities
(e.g., administrative staff)."
Now, if administrative hospital staff
do not need to wear masks,
why would healthy individuals need to
wear them when walking around, especially in open-air areas?
Broward county, Florida, has gone so far as to issue an emergency
order 12 mandating masks to be worn inside your own residence.
why, if administrative hospital staff aren't even advised to wear
them at work?
In summary, it is likely that masks are not entirely useless in all
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
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.
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 include: 13
"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:
"Encouraging the public to create their own fabric masks may promote
individual enterprise and community integration...
The production of
non-medical masks may offer a source of income for those able to
manufacture masks within their communities.
Fabric masks can also be
a form of cultural expression, encouraging public acceptance of
protection measures in general."
Potential Harms and Risks of Mask Wearing
The WHO also lists a number of potential harms and risks of mask
"should be carefully taken into account when adopting
this approach of targeted continuous medical mask use."
Self-contamination due to the manipulation of the mask by
contaminated hands or not changing the mask when wet, soiled or
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,
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
demonstration 15 (see bitchute video below). With an N95 mask on, the
carbon dioxide level spikes above 8,480 ppm within seconds.
5,000 ppm, OSHA warns that "toxicity or oxygen deprivation could
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
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 trigger. 16
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
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, 2020: 19
"The French non-profit Opération Mer Propre, whose activities
include regularly picking up litter along the Côte d'Azur, began
sounding the alarm late last month.
Divers had found what Joffrey Peltier of the organization described
as 'COVID waste' - dozens of gloves, masks and bottles of hand
sanitizer beneath the waves of the Mediterranean, mixed in with the
usual litter of disposable cups and aluminum cans...

In France alone, authorities have ordered two billion disposable
masks, said Laurent Lombard of Opération Mer Propre.

masks and swap latex gloves for more frequent handwashing.
the alternatives, plastic isn't the solution to protect us from COVID. That's the message,' said Peltier."
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.

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

There are several vaccine candidates in clinical trials, and some
look promising at providing a level of protection against COVID-19.
While no vaccine has been approved yet by the Food and Drug
Administration (FDA), experts are already grappling with how to
convince the American public to get vaccinated.
Vaccine hesitancy has been a public health issue for several years
now, especially among parents of young children, partly due to the
rise of misinformation on social media.
Polls have also shown people of color are less likely to want to get
vaccinated, which experts say could be explained by distrust of a
public health infrastructure that has a history of mistreatment and

color in the health care system is the Tuskegee syphilis study, in

People of color still face racism in health settings and disparities
in access to health care in the U.S.

would not get a COVID-19 vaccine available today if it were free and
approved by the FDA.
Sixty-seven percent of white Americans said they would get the
vaccine, compared to 59 percent of nonwhite Americans. People who
lived in rural areas were less likely to say they would get
vaccinated than people who lived in small towns, suburbs or large
