MASK Science
Stole this from Chris Bowen in another group
Below you will find over 40 peer reviewed research articles related to the uselessness of wearing face masks and the science of face masks.
Here are key anchor points to the extensive scientific literature that establishes that wearing surgical masks and respirators (e.g., “N95”) does not reduce the risk of contracting a verified illness:
• Jacobs, J. L. et al. (2009) “Use of surgical face masks to reduce the incidence of the common cold among health care workers in Japan: A randomized controlled trial,” American Journal of Infection Control, Volume 37, Issue 5, 417 – 419.
N95-masked health-care workers (HCW) were significantly more likely to experience headaches. Face mask use in HCW was not demonstrated to provide benefit in terms of cold symptoms or getting colds.
• Cowling, B. et al. (2010) “Face masks to prevent transmission of influenza virus: A systematic review,” Epidemiology and Infection, 138(4), 449-456. DOI:10.1017/S0950268809991658
None of the studies reviewed showed the benefit of wearing a mask in either HCW or community members in households (H). See summary Tables 1 and 2 therein.
• bin-Reza et al. (2012), “The use of masks and respirators to prevent transmission of influenza: a systematic review of the scientific evidence,” Influenza and Other Respiratory Viruses 6(4), 257-267.
“There were 17 eligible studies. […] None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection.”
• Smith, J.D. et al. (2016) “Effectiveness of N95 respirators versus surgical masks in protecting health care workers from acute respiratory infection: a systematic review and meta-analysis”, CMAJ Mar 2016, cmaj.150835; DOI: 10.1503/cmaj.150835
“We identified 6 clinical studies … In the meta-analysis of the clinical studies, we found no significant difference between N95 respirators and surgical masks in the associated risk of (a) laboratory-confirmed respiratory infection, (b) influenza-like illness, or (c) reported work-place absenteeism.”
• Offeddu, V. et al. (2017) “Effectiveness of Masks and Respirators Against Respiratory Infections in Healthcare Workers: A Systematic Review and Meta-Analysis,” Clinical Infectious Diseases, Volume 65, Issue 11, 1 December 2017, Pages 1934-1942,
• Radonovich, L.J. et al. (2019) “N95 Respirators vs. Medical Masks for Preventing Influenza Among Health Care Personnel: A Randomized Clinical Trial”, JAMA. 2019; 322(9): 824-833. DOI:10.1001/jama.2019.11645
“Among 2862 randomized participants, 2371, completed the study and accounted for 5180 HCW-seasons. … Among outpatient health care personnel, N95 respirators vs. medical masks as worn by participants in this trial resulted in no significant difference in the incidence of laboratory-confirmed influenza.”
• Long, Y. et al. (2020) “Effectiveness of N95 respirators versus surgical masks against influenza: A systematic review and meta-analysis”, J Evid Based Med. 2020; 1- 9.
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.
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.
Many potential harms may arise from broad public policies to wear masks, and the following unanswered questions arise:
• Do used and loaded masks become sources of enhanced transmission, for the wearer and others?
• Do masks become collectors and retainers of pathogens that the mask wearer would otherwise avoid when breathing without a mask?
• Are large droplets captured by a mask atomized or aerosolized into breathable components? Can virions escape an evaporating droplet stuck to a mask fiber?
• What are the dangers of bacterial growth on a used and loaded mask?
• How do pathogen-laden droplets interact with environmental dust and aerosols captured on the mask?
• What are long-term health effects on HCW, such as headaches, arising from impeded breathing?
• Are there negative social consequences to a masked society?
• Are there negative psychological consequences of wearing a mask, as a fear-based behavioral modification?
• What are the environmental consequences of mask manufacturing and disposal?
• Do the masks shed fibers or substances that are harmful when inhaled?

In this video, Tammy K. Herrema Clark, an authorized OSHA Instructor / Consultant, and a PPE (Personal Protective Equipment) expert of 20 years mentions that in operating rooms they make sure there’s extra oxygen in the room. It’s illegal to simply hand out N95 masks to anybody without a medical evaluation first.
Now the government, not OSHA, is dictating to OSHA to support the COVID-19 plan regardless of safety concerns. This is why OSHA is actually violating their own standards.
This is an excellent video on the Science of wearing a mask from two experts in PPE, Work place safety and OSHA standards. They talk about all of the OSHA standards. How OSHA has a medical questionnaire that has to be filled out prior to wearing a mask. A whole long list of all of the different medical reasons that OSHA would not approve a mask for most people.
Here is the questionnaire
They also cover the “Doctors wear masks all day and are fine nonsense”
And why the videos of nurses with pulse oximeters saying they are fine are not science.
They explain everything that goes into a fit test for wearing a mask.
They cover what to do if your employer mandates you wearing a mask. What rights you have.
They talk about the dangers for pregnant women and the fetus of wearing a mask.
They talk about schools and what to do about sending kids back to school or if you are a teacher.
I’m sure I am forgetting some things, they covered a lot. Well worth watching all the way through if you have time.…/posts/10164079731495494…
