Major Medical Groups and Journals do NOT support the wearing of face masks by the public
From the World Health Organization (WHO):
- “There is limited evidence that wearing a medical mask by healthy individuals in the households or amongcontacts of a sick patient, or among attendees of mass gatherings may be beneficial as a preventive measure.14- 23 However, there is currently no evidence that wearing a mask (whether medical or other types) by healthy persons in the wider community setting, including universal community masking, can prevent them from infection with respiratory viruses, including COVID-19.”
- “Many countries have recommended the use of fabric masks/face coverings for the general public. At the present time, the widespread use of masks by healthy people in the community setting is not yet supported by high quality or direct scientific evidence and there are potential benefits and harms to consider.”
- potential increased risk of self-contamination due to the manipulation of a face mask and subsequently touching eyes with contaminated hands
- potential self-contamination that can occur if non-medical masks are not changed when wet or soiled. This can create favourable conditions for microorganism to amplify
- potential headache and/or breathing difficulties, depending on type of mask used.
- a false sense of security, leading to potentially lower adherence to other critical preventive measures such as physical distancing and hand hygiene;
On April 21, 2020, the American Medical Association released a position paper on masks. It made several point that bring the issue of the public wearing face masks into question, including…
• “Face masks should be used only by individuals who have symptoms of respiratory infection such as coughing, sneezing, or, in some cases, fever. Face masks should also be worn by healthcare workers, by individuals who are taking care of or are in close contact with people who have respiratory infections, or otherwise as directed by a doctor. Face masks should not be worn by healthy individuals to protect themselves from acquiring respiratory infection because there is no evidence to suggest that face masks worn by healthy individuals are effective in preventing people from becoming ill.” https://jamanetwork.com/journals/jama/fullarticle/2762694
Journal of Paediatrics and Child Health: June 2020
- “There is no good evidence that facemasks protect the public against infection with respiratory viruses, includingCOVID-19.”
- “During the 2009 pandemic of H1N1 influenza (swine flu),encouraging the public to wash their hands reduced the incidence of infection significantly whereas wearing facemasks didnot.5There is no good evidence that facemasks protect the public against infection with respiratory viruses, including COVID-19.” https://onlinelibrary.wiley.com/doi/epdf/10.1111/jpc.14936
New England Journal of Medicine- May 2020- Universal Masking in Hospitals in the Covid-19 Era“We know that wearing a mask outside health care facilities offers little, if any, protection from infection. Public health authorities define a significant exposure to Covid-19 as face-to-face contact within 6 feet with a patient with symptomatic Covid-19 that is sustained for at least a few minutes (and some say more than 10 minutes or even 30 minutes). The chance of catching Covid-19 from a passing interaction in a public space is therefore minimal. In many cases, the desire for widespread masking is a reflexive reaction to anxiety over the pandemic.” https://pubmed.ncbi.nlm.nih.gov/32237672/
A review of highly rated studies:
A meta-analysis of 17 of the best studies determined the following: “None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection.” bin-Reza F et al.

Face masks restrict the elimination of virus, recirculating the virus into the nasal/sinus and upper respiratory passages and can infect the brain.
“By wearing a mask, the exhaled viruses will not be able to escape and will concentrate in the nasal passages, enter the olfactory nerves and travel into the brain.”….“We know that people who have the worst reactions to the coronavirus have the highest concentrations of the virus early on.” Face masks will contribute to this.

Wearing masks can increase the chance of infection
Most people do not even know how to wear or use them.
US surgeon general warns against wearing face coverings.
A Cluster Randomised Trial of Cloth Masks Compared With Medical Masks in Healthcare Workers (British Medical Journal).
“The rates of all infection outcomes were highest in the cloth mask arm…Penetration of cloth masks by particles was almost 97% and medical masks 44%…Conclusions: This study is the first RCT of cloth masks, and the results caution against the use of cloth masks. This is an important finding to inform occupational health and safety. Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection. Further research is needed to inform the widespread use of cloth masks globally. However, as a precautionary measure, cloth masks should not be recommended for HCWs, particularly in high-risk situations, and guidelines need to be updated.” https://pubmed.ncbi.nlm.nih.gov/25903751/ (PMID: 25903751)

CDC echoes the concern:
“Available evidence shows that (cloth masks)… may even increase the risk of infection due to moisture, liquid diffusion and retention of the virus. Penetration of particles through cloth is reported to be high.” “Altogether, common fabric cloth masks are not considered protective against respiratory viruses and their use should not be encouraged.” https://www.cdc.gov/coronavirus/2019-ncov/hcp/ppe-strategy/face-masks.html
The British Medical Journal weighs in:
“Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection.” “The virus may survive on the surface of the facemasks.”
“Self-contamination through repeated use and improper doffing is possible.” https://bmjopen.bmj.com/content/5/4/e006577

There is a danger of masks reducing oxygen (O2) levels and increasing levels of Carbon Dioxide (CO2) to unsafe levels
“Wearing N95 masks results in hypo-oxygenemia (levels of oxygen in the blood) and hypercapnia (is increased levels of carbon dioxide), which reduce working efficiency and the ability to make correct decision.”
“Medical staff are at increased risk of getting ‘Severe acute respiratory syndrome’ (SARS), and wearing N95 masks is highly recommended by experts worldwide. However, dizziness, headache, and short of breath are commonly experienced by the medical staff wearing N95 masks. The ability to make correct decision may be hampered, too.” https://clinicaltrials.gov/ct2/show/NCT00173017 https://www.researchgate.net/…/7332926_Headaches_and_the_N9…

- “Chronic hypoxia-hypercapnia influences cognitive function”https://www.ncbi.nlm.nih.gov/pubmed/18331781
- A recent study involving 159 healthcare workers aged 21 to 35 years of age found that 81% developed headaches from wearing a face mask… That is, a reduction in blood oxygenation (hypoxia) or an elevation in blood carbon dioxide (C02- (hypercapnia). It is known that the N95 mask, if worn for hours, can reduce blood oxygenation as much as 20%. And proper oxygenation of the blood is essential for energy, mental clarity, focus and emotional well-being. Ong JJY et al.

Headache 2020;60(5):864-877. https://headachejournal.onlinelibrary.wiley.com/doi/epdf/10.1111/head.13811
- “Hypercapnia, the elevation of carbon dioxide (CO2) in blood and tissues, commonly occurs in severe acute and chronic respiratory diseases, and is associated with increased risk of mortality. Recent studies have shown that hypercapnia adversely affects innate immunity, host defense, lung edema clearance and cell proliferation. Airway epithelial dysfunction is a feature of advanced lung disease….These changes in gene expression indicate the potential for hypercapnia to impact bronchial epithelial cell function in ways that may contribute to poor clinical outcomes in patients with severe acute or advanced chronic lung diseases.” This clearly can have a negative impact with a disease like COVID-19. https://www.nature.com/articles/s41598-018-32008-x.pdf

Different types of masks and their effectiveness
This 2015 study published by the British Medical Journal titled, A cluster randomised trial of cloth masks compared with medical masks in healthcare workers, compares the use of cloth masks and medical masks and warns against the use of cloth masks, due to their increased rick of transmitting infection, especially in health care workers. While this study looked at health care workers specifically, the results can be extrapolated to mask use by the general public.
From the results: “Penetration of cloth masks by particles was almost 97% and medical masks 44%.” This shows the almost complete ineffectiveness of cloth masks and correlates closely with many other studies, some of them presented below.
The conclusion: “This study is the first RCT of cloth masks, and the results caution against the use of cloth masks. This is an important finding to inform occupational health and safety. Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection. Further research is needed to inform the widespread use of cloth masks globally. However, as a precautionary measure, cloth masks should not be recommended for HCWs, particularly in high-risk situations, and guidelines need to be updated.”
A real-world observation:
With near universal use of cloth and medical masks worn in public in Wuhan, China during the 2019-2020 flu season leading up to the COVID-19 outbreak, the outbreak spread virtually unchecked.

Unmasking the Surgeons: The Evidence Base Behind the Use of Facemasks in Surgery (Journal of the Royal Society of Medicine) “Examination of the literature revealed much of the published work on the matter to be quite dated and often studies had poorly elucidated methodologies. As a result, we recommend caution in extrapolating their findings to contemporary surgical practice. However, overall there is a lack of substantial evidence to support claims that face masks protect either patient or surgeon from infectious contamination. More rigorous contemporary research is needed to make a definitive comment on the effectiveness of surgical facemasks.”

Transmission of viruses from breathing requires extended time of contact for even low transmission
From the journal Nature Medicine, April 2020 titled, Respiratory virus shedding in exhaled breath and efficacy of face masks.
From the study: “Among the samples collected without a face mask, we found that the majority of participants with influenza virus and coronavirus infection did not shed detectable virus in respiratory droplets or aerosols,…. given that each exhaled breath collection was conducted for 30 min, this might imply that prolonged close contact would be required for transmission to occur, even if transmission was primarily via aerosols, as has been described for rhinovirus colds.” https://www.nature.com/articles/s41591-020-0843-2
The Surgical Mask Is a Bad Fit for Risk Reduction (Canadian Medical Association Journal)- 2016
“Histories of the surgical mask offer some clues about our contemporary risk profile, a profile that is, according to the nature of risk, future-oriented. The birth of the mask came from the realization that surgical wounds need protection from the droplets released in the breath of surgeons. The technology was applied outside the operating room in an effort to control the spread of infectious epidemics. In the 1919 influenza pandemic, masks were available and were dispensed to populations, but they had no impact on the epidemic curve. At the time, it was unknown that the influenza organism is nanoscopic and can theoretically penetrate the surgical mask barrier. As recently as 2010, the US National Academy of Sciences declared that, in the community setting, “face masks are not designed or certified to protect the wearer from exposure to respiratory hazards.” A number of studies have shown the inefficacy of the surgical mask in household settings to prevent transmission of the influenza virus.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4868614/
Frequent washing and drying of a cloth mask can decrease the filtration capacity of the mask.
Optical microscopic study of surface morphology and filtering efficiency of face masks (Journal of Life and Environmental Sciences) “We studied the effect of surface morphology of locally available face masks on their PM filtering efficiency. Filtering efficiency of CM for ambient PM10 was poorer than in SM. The poor efficiency was due to the presence of larger sized pores. Our study also demonstrated that washing and drying cycle deteriorates the filtering efficiency due to change in pore shape and clearance. We also found that stretching of the CM surface alters the pore size and potentially decreases the filtering efficiency. The findings of this study suggest that CM are not effective, and that effectiveness deteriorates if used after washing and drying cycles and if used under stretched condition.” (CM = cloth mask, PM = particulate matter, SM = surgical mask) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6599448/
Fear induced immunocompromise from wearing face masks
Wearing face masks is a constant reminder that we should fear this invisible enemy or “monster” as some politicians have called it- There is no doubt that wearing a mask reinforces the worry and fear about COVID-19. Even being in public mask-less and seeing that most people are wearing masks leaves one with a sense of angst. Fear, worry and anxiety are powerful immune suppressing emotions. This is another factor relating to the immunosuppressive effects of face masks. This is a link to a section of a 2007 book titled, Cytokines: Stress and Immunity- Second Edition 2007. You can read Chapter 2 titled Worried to Death? Worry, and Immune Dysregulation in Health and HIV. Interestingly, HIV is a viral infection as is SARS-C0V-2 (COVID-19). https://books.google.com/books?hl=en&lr=&id=2DvMBQAAQBAJ&oi=fnd&pg=PA17&dq=the+immunosuppressive+effec ts+of+fear+and+worry&ots=ZNbmH2FBXA&sig=0FwVcXAxtEBeHT78_EV90NWl91g
Other harms from wearing masks:
Textile materials (that can be used for cloth masks) can contain harmful chemicals and dyes (i.e. formaldehyde). There is no research available regarding the safety of breathing through such materials, but formaldehyde is a gas that can irritate a person’s eyes, nose, throat and lungs, or trigger an asthma attack, even at low concentrations. Prolonged exposure to formaldehyde can cause cancer.
