Wearing a mask may soon be mandatory depending on where you live and this is causing a debate about whether or not masks are actually effective when it comes to protecting your health during a pandemic. Multiple studies have now concluded that masks are not only ineffective but they in fact offer a disadvantage to those who choose to wear them. In this video Del Bigtree talks wiyh with Denis Rancourt a PhD and former professor of physics at the University of Ottawa about a paper he wrote titled “Masks Don’t Work: A Review of Science Relevant to COVID-19 Social Policy” to discuss the science behind masks, why they don’t work and how society should handle this highly contentious issue moving forward.

Abstract

Masks and respirators do not work. There have been extensive randomized controlled trial (RCT) studies, and meta-analysis reviews of RCT studies, which all show that masks and respirators do not work to prevent respiratory influenza-like illnesses, or respiratory illnesses believed to be transmitted by droplets and aerosol particles. Furthermore, the relevant known physics and biology, which I review, are such that masks and respirators should not work. It would be a paradox if masks and respirators worked, given what we know about viral respiratory diseases: The main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective-dose is smaller than >

Conclusion Regarding that Masks Do Not Work

No RCT study with verified outcome shows a benefit for HCW or community members in
households to wearing a mask or respirator. There is no such study. There are no exceptions.
Likewise, no study exists that shows a benefit from a broad policy to wear masks in public
(more on this below).
Furthermore, if there were any benefit to wearing a mask, because of the blocking power
against droplets and aerosol particles, then there should be more benefit from wearing a
respirator (N95) compared to a surgical mask, yet several large meta-analyses, and all the RCT,
prove that there is no such relative benefit.
Masks and respirators do not work.

Precautionary Principle Turned on Its Head with Masks

In light of the medical research, therefore, it is difficult to understand why public-health
authorities are not consistently adamant about this established scientific result, since the
distributed psychological, economic and environmental harm from a broad recommendation to
wear masks is significant, not to mention the unknown potential harm from concentration and
distribution of pathogens on and from used masks. In this case, public authorities would be
turning the precautionary principle on its head (see below).

Physics and Biology of Viral Respiratory Disease and of Why Masks Do Not Work

In order to understand why masks cannot possibly work, we must review established
knowledge about viral respiratory diseases, the mechanism of seasonal variation of excess
deaths from pneumonia and influenza, the aerosol mechanism of infectious disease
transmission, the physics and chemistry of aerosols, and the mechanism of the so-called
minimum-infective-dose.


In addition to pandemics that can occur anytime, in the temperate latitudes there is an extra burden of respiratory-disease mortality that is seasonal, and that is caused by viruses. For example see the review of influenza by Paules and Subbarao (2017). This has been known for a long time, and the seasonal pattern is exceedingly regular.

A doctor in the UK who was banned from using social media by the General Medical Council for claiming “masks do nothing” has won his case in the High Court. Dr. Samuel White was slapped with and 18 month ban by the GMC after he posted a video to Instagram and Twitter in June questioning the efficacy of face coverings. In the video, White said why he could no longer tolerate working in his previous roles because of the “lies” around the NHS and the government’s response to the pandemic, which were “so vast

There are NO randomized, controlled trials (RCT) with verified outcomes that show a benefit to healthcare workers or community members for wearing a mask or a respirator. There is no such definitive study. Likewise, no study exists that shows a benefit from a broad policy to wear masks in public (documented below).
