Mask wearing a placebo
Recently, opinion columns and letter writers have espoused on the medical benefits of wearing masks and the science supporting it without ever providing that science so I decided to do it. Listed below are the periodical, date, title and quote lifted from the findings.
New England Journal of Medicine, May 21, 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. The desire for widespread masking is a reflexive reaction to anxiety over the pandemic.”
Science Direct, Vol. 20, Sept. 2017, Effectiveness of personal protective measures in reducing pandemic influenza transmission, “Facemark use provided a non-significant protective effect.”
Annals of Internal Medicine, July 7, 2020, Effectiveness of Surgical and Cotton Masks in Blocking SARS-CoV-2, “Neither surgical nor cotton masks effectively filtered SARS–CoV-2.”
British Medical Journal, 2015, A cluster randomized trial of cloth masks compared with medical masks in healthcare workers, “Penetration of cloth masks by particles was almost 97% and medical masks 44%. This study is the first RCT of cloth masks, and caution against their use.”
Journal of Exposure Science & Environmental Epidemiology, Aug 17, 2016, Evaluating the Efficacy of Cloth Facemarks in Reducing particulate exposure, “Cloth masks are only marginally beneficial. Compared with cloth masks, disposable surgical masks are more effective in reducing particulate exposure.”
CDC, Volume 26 No. 5 May 2020, Nonpharmaceutical Measures for Pandemic Influenza in Non-healthcare Settings-PPE Measures, “In pooled analysis we found no significant reduction influenza transmission with the use of face masks."
Thus the wearing of face masks (other than N95 and above) is mere placebo. Local citizens forced to wear masks by their employers should be aware that these masks have not been tested nor certified by OSHA as safe and effective. Masks can cause hypoxia, hypercapnia, impair one’s immunity, trap viruses in the respiratory tract and/or in one’s nasal passages which could then enter the brain via olfactory nerves. Employers are legally liable for any employee illness caused by the wearing of masks as well as the UW being legally liable for any student illness attributable to masks.

Okay, then. This is my new little project: to find the articles and find out what I think of all this.
