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 one aerosol particle.
The present paper about masks illustrates the degree to which governments, the mainstream media, and institutional propagandists can decide to operate in a science vacuum, or select only incomplete science that serves their interests. Such recklessness is also certainly the case with the current global lockdown of over 1 billion people, an unprecedented experiment in medical and political history.
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 have seen a number of medical practices that have little or no scientific support as regards reducing the spread of COVID-19 infection. One of these measures is the wearing of facial masks, either a surgical-type mask, bandana or N95 respirator mask. When this pandemic began and we knew little about the virus itself or its epidemiologic behavior, it was assumed that it would behave, in terms of spread among communities, like other respiratory viruses. Little has presented itself after intense study of this virus and its behavior to change this perception.
Now that we have established that there is no scientific evidence necessitating the wearing of a face mask for prevention, are there dangers to wearing a face mask, especially for long periods? Several studies have indeed found significant problems with wearing such a mask. This can vary from headaches, to increased airway resistance, carbon dioxide accumulation, to hypoxia, all the way to serious life-threatening complications.
One should not attack and insult those who have chosen not to wear a mask, as these studies suggest that is the wise choice to make.
What we’re seeing is a lot of magical thinking. A lot of wishful thinking. Cloth masks are wishful thinking.
The idea that cloth masks will protect anybody from contracting COVID-19 is magical thinking, Lisa Brousseau, ScD, expert on infectious diseases, Professor (retired), University of Illinois at Chicago, tells Infection Control Today.
"I would really strongly encourage hospitals to stop asking people to send them cloth masks and instead asked for respirators. I don’t necessarily discourage the public from wearing them if it makes them feel comfortable, but I hope they don’t think that they’re protecting themselves."
Their use may result in those wearing the masks to relax other distancing efforts because they give a false sense of protection.
“There is no specific evidence to suggest that the wearing of masks by the mass population has any potential benefit,” Dr. Mike Ryan, an epidemiologist who specializes in infectious diseases and public health and who is the executive director of the WHO health emergencies program, said at a media briefing. “In fact, there’s some evidence to suggest the opposite in the misuse of wearing a mask properly or fitting it properly”
During the COVID-19 pandemic, public health experts began telling us to follow a number of disease mitigation strategies that sounded reasonably scientific, but actually had little or no support in the scientific literature. Community wearing of masks was one of the more dangerous recommendations from our confused public health experts.
