Fask Facts -The Association of American Physicians and Surgeons

A curated list of mask facts and medical publications.

COVID-19 is as politically-charged as it is infectious. Early in the COVID-19 pandemic, the WHO, the CDC and NIH’s Dr. Anthony Fauci discouraged wearing masks as not useful for non-health care workers. Now they recommend wearing cloth face coverings in public settings where other social distancing measures are hard to do (e.g., grocery stores and pharmacies). The recommendation was published without a single scientific paper or other information provided to support that cloth masks actually provide any respiratory protection. Let’s look at the data.

  • Surgical masks are loose fitting. They are designed to protect the patient from the doctors’ respiratory droplets.  There wearer is not protected from others’ airborne particles.
  • People do not wear masks properly. Many people have the mask under the nose. The wearer does not have glasses on and the eyes are a portal of entry.  If the virus lands on the conjunctiva, tears will wash it into the nasopharynx.
  • Most studies cannot separate out hand hygiene.
  • The designer masks and scarves offer minimal protection. They give a false sense of security to both the wearer and those around the wearer.
    **Not to mention they add a perverse lightheartedness to the situation.
  • If you are walking alone, no need for a mask. Avoid other folks; use common sense.
  • Remember: children under 2 years should not wear masks because of accidental suffocation and difficulty breathing in some.
  • Even if a universal mask mandate were imposed, several studies noted that folks do not use the mask properly and over-report their wearing.  Additionally, how would the mandate be enforced??
  • The positive studies are models that assume universality and full compliance.
  • If wearing a mask makes people go out and get Vitamin D – go for it. In the 1918 flu pandemic people who went outside did better.  Early reports are showing people with COVID-19 with low Vitamin D do worse than those with normal levels. Perhaps that is why shut-ins do so poorly.

Denis Rancourt on the effectiveness of masks

  • Science has already proved that masks don’t work.
  • Many large Randomised Control Trials (RCT) and meta-analyses over the past decade show masks offer no reduction in risk from respiratory viruses.
  • We understand the mechanism of transmission of respiratory disease and the science is clear that masks can’t work.
  • It can’t help others when you’re breathing out and it can’t help you when you’re breathing in.
  • The mechanism of transmission is through very small aerosol particles.
  • Any opening in the mask will allow enough of the minimal dose to infect you.
  • One of the effects shown in studies with healthcare workers is that they had an increase in headaches.
  • Many articles in support of masks are not relevant e.g. masks stop droplets but transmission is not via droplets.
  • Diseases are seasonal because droplets are carried for a long time when the air is dry like in the winter.

Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures – CDC

There were 3 influenza pandemics in the 20th century, and there has been 1 so far in the 21st century. Local, national, and international health authorities regularly update their plans for mitigating the next influenza pandemic in light of the latest available evidence on the effectiveness of various control measures in reducing transmission. Here, we review the evidence base on the effectiveness of nonpharmaceutical personal protective measures and environmental hygiene measures in nonhealthcare settings and discuss their potential inclusion in pandemic plans. 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. We similarly found limited evidence on the effectiveness of improved hygiene and environmental cleaning. We identified several major knowledge gaps requiring further research, most fundamentally an improved characterization of the modes of person-to-person transmission.

Effect of a surgical mask on six minute walking distance – PubMed (2017)

Results: Distance was not modified by the mask (P=0.99). Dyspnea variation was significantly higher with surgical mask (+5.6 vs. +4.6; P<0.001) and the difference was clinically relevant. No difference was found for the variation of other parameters.

Conclusion: Wearing a surgical mask modifies significantly and clinically dyspnea without influencing walked distance.
