Thread: Masks

The mask covidian cult are starting to sound the alarm again and expand their cult programming to basically any respiratory illness in order to normalize their cult rituals. RT far & wide if you find this useful.

I’d thought it would be informative to start a thread with much of but not all of the evidence that refutes their maniacal beliefs. I’ve only provided a small sample size over all but it’s a good start.

Unfortunately mask covidian cultists have come to believe that wearing a surgical mask is a great way to protect yourself and others from Flu, COVID and getting hit by a bus while walking alone down the street or even while driving alone.

If you have a covidian cultist in your life please share the following information with them. Even though I highly doubt they will assimilate it and allow it to inform themselves moving forward, hey at least you tried.

There is a common belief that N95 masks are better, you’ve seen them in public, tightly strapped to the faces of the fearful. I’m sure if we could see their face there would be a self satisfied smug look on them while they struggle to breathe. So let take a look at the evidence.

“N95 Respirators vs Medical Masks for Preventing Influenza Among Health Care Personnel: A Randomized Clinical Trial
Lewis J Radonovich Jr et al. JAMA. 2019”

Study Objective: To compare the effect of N95 respirators vs medical masks for prevention of influenza and other viral respiratory infections among HCP.

Design, setting, and participants: A cluster randomized pragmatic effectiveness study conducted at 137 outpatient study sites

at 7 US medical centers between September 2011 and May 2015, with final follow-up in June 2016. Each year for 4 years, during the 12-week period of peak viral respiratory illness, pairs of outpatient sites within each center were matched and randomly assigned to the N95 or mask.

Interventions: Overall, 1993 participants in 189 clusters were randomly assigned to wear N95 respirators (2512 HCP-seasons of observation) and 2058 in 191 clusters were randomly assigned to wear medical masks (2668 HCP-seasons) when near patients with respiratory illness.

Conclusions and relevance: 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.

NO SIGNIFICANT DIFFERENCE IN THE INCIDENCE OF LABORATORY-CONFIRMED INFLUENZA

In case you are thinking that flu virus and SARS Cov 2 are different size wise and therefore cannot be compared, you are wrong. They are similar in size to the point of parody.

“Face masks to prevent transmission of influenza virus: a systematic review
Published online by Cambridge University Press:  22 January 2010”

cambridge.org/core/journals/…

“We conducted a systematic review [Reference Moher 6] to investigate the evidence supporting the effectiveness of face masks in reducing influenza virus infection under controlled and natural conditions.”

“Our review highlights the limited evidence base supporting the efficacy or effectiveness of face masks to reduce influenza virus transmission.”

“One concern over the use of face masks or respirators in healthcare settings is the potential for negative psychosocial impacts on patients and children in particular, especially in regions outside Asia where masks are not routinely worn.”

“Pandemic guidance provided by the World Health Organization for community settings advises that masks may be worn although effectiveness is uncertain particularly in open spaces [41].

“Other health agencies, such as the US Centers for Disease Control and Prevention, are not recommending masks in the community setting, with the exception of high-risk individuals who care for the sick or spend time in large crowds in areas affected by the pandemic [42]. “

“Wearing masks incorrectly may increase the risk of transmission.”

INCREASE TRANSMISSION

“In conclusion there remains a substantial gap in the scientific literature on the effectiveness of face masks to reduce transmission of influenza virus infection.”

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. ncbi.nlm.nih.gov/pubmed/19216002

“Background: Health care workers outside surgical suites in Asia use surgical-type face masks commonly. Prevention of upper respiratory infection is one reason given, although evidence of effectiveness is lacking.”

“Methods: Health care workers in a tertiary care hospital in Japan were randomized into 2 groups: 1 that wore face masks and 1 that did not. They provided information about demographics, health habits, and quality of life. Participants recorded symptoms daily for 77 consecutive..

days, starting in January 2008. Presence of a cold was determined based on a previously validated measure of self-reported symptoms. The number of colds between groups was compared, as were risk factors for experiencing cold symptoms.”

“Conclusion: Face mask use in health care workers has not been demonstrated to provide benefit in terms of cold symptoms or getting colds. A larger study is needed to definitively establish noninferiority of no mask use.”

“Effectiveness of N95 respirators versus surgical masks in protecting health care workers from acute respiratory infection: a systematic review and meta-analysis”

“Background: Conflicting recommendations exist related to which facial protection should be used by health care workers to prevent transmission of acute respiratory infections, including pandemic influenza. We performed a systematic review of both clinical and surrogate exposure

“data comparing N95 respirators and surgical masks for the prevention of transmissible acute respiratory infections.”

“Methods: We searched various electronic databases and the grey literature for relevant studies published from January 1990 to December 2014. Randomized controlled trials (RCTs), cohort studies and case–control studies that included data on health care workers wearing N95…

respirators and surgical masks to prevent acute respiratory infections were included in the meta-analysis.”

“Conclusion: Although N95 respirators appeared to have a protective advantage over surgical masks in laboratory settings, our meta-analysis showed that there were insufficient data to determine definitively whether N95 respirators are superior to surgical masks in protecting..

health care workers against transmissible acute respiratory infections in clinical settings.”

“N95 Respirators vs Medical Masks for Preventing Influenza Among Health Care Personnel: A Randomized Clinical Trial,” JAMA. 2019; 322(9): 824–833.

jamanetwork.com/journals/jama/…

“Question: Is the use of N95 respirators or medical masks more effective in preventing influenza infection among outpatient health care personnel in close contact with patients with suspected respiratory illness?”

“Findings: In this pragmatic, cluster randomized clinical trial involving 2862 health care personnel, there was no significant difference in the incidence of laboratory-confirmed influenza among health care personnel with the use of N95 respirators (8.2%) vs medical masks (7.2%).

“Meaning: As worn by health care personnel in this trial, use of N95 respirators, compared with medical masks, in the outpatient setting resulted in no significant difference in the rates of laboratory-confirmed influenza.”

Study 7:

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. onlinelibrary.wiley.com/doi/epdf/10.11…

“A total of six RCTs involving 9,171 participants were included. There were no statistically significant differences in preventing laboratory-confirmed influenza, laboratory-confirmed respiratory viral infections, laboratory-confirmed respiratory infection,..

and influenza-like illness using N95 respirators and surgical masks. Meta-analysis indicated a protective effect of N95 respirators against laboratory-confirmed bacterial colonization (RR = 0.58, 95% CI 0.43-0.78)...

The use of N95 respirators compared with surgical masks is not associated with a lower risk of laboratory-confirmed influenza.”

“A cluster randomised trial of cloth masks compared with medical masks in healthcare workers”

ncbi.nlm.nih.gov/pmc/articles/P…

“The aim of this study was to compare the efficacy of cloth masks to medical masks in hospital healthcare workers (HCWs). The null hypothesis is that there is no difference between medical masks and cloth masks.”

“Participants: 1607 hospital HCWs aged ≥18 years working full-time in selected high-risk wards.”

“Intervention: Hospital wards were randomised to: medical masks, cloth masks or a control group (usual practice, which included mask wearing)...

Participants used the mask on every shift for 4 consecutive weeks.”

“Conclusions: This study is the first RCT of cloth masks, and the results caution against the use of cloth masks. This is an important finding to inform occupational health and safety. Moisture retention,..

reuse of cloth masks and poor filtration may result in increased risk of infection.”

Study 9:

“Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures”

wwwnc.cdc.gov/eid/article/26…

“In this review, we did not find evidence to support a protective effect of personal protective measures or environmental measures in reducing influenza transmission.”

“We did not find evidence that surgical-type face masks are effective in reducing laboratory-confirmed influenza transmission, either when worn by infected persons (source control) or by persons in the general community to reduce their susceptibility.”

Now let’s look at some studies that show the negative health effects of mask wearing. The mask cult will have you believe that wearing something that inhibits your breathing all day is perfectly healthy, how could it possibly impact your health?

1.

[Effect of a surgical mask on six minute walking distance]

pubmed.ncbi.nlm.nih.gov/29395560/

“Introduction: Six minutes walking test (6MWT) is regularly used in pulmonology. To minimize the risk of cross-infection, some patients must wear surgical mask at rest and sometimes during exercise.”

“Aim of the study: To evaluate the effect of wearing a surgical mask during 6MWT in healthy subjects.”

“Material and method: It is a prospective study on 44 healthy subjects. After a first 6MWT for training, they performed randomly two 6MWT: with or without a surgical mask. Distance and dyspnea, heart rate and saturation variations were recorded.”

“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.”

Note: dyspnea means shortness of breath

“The physiological impact of wearing an N95 mask during hemodialysis as a precaution against SARS in patients with end-stage renal disease”

pubmed.ncbi.nlm.nih.gov/15340662/

“Background and purpose: Most patients with end-stage renal disease (ERSD) visiting our hospital for hemodialysis treatment during the SARS outbreak wore an N95 mask. Data on the physiological stress imposed by the wearing of N95 masks remains limited...

This study investigated the physiological impact of wearing an N95 mask during hemodialysis (HD) on patients with ESRD.”

“Conclusion: Wearing an N95 mask for 4 hours during HD significantly reduced PaO2 and increased respiratory adverse effects in ESRD patients.”

“Respiratory consequences of N95-type Mask usage in pregnant healthcare workers-a controlled clinical study”

pubmed.ncbi.nlm.nih.gov/26579222/

“Conclusions: Breathing through N95 mask materials have been shown to impede gaseous exchange and impose an additional workload on the metabolic system of pregnant healthcare workers, and this needs to be taken into consideration in guidelines for respirator use...

The benefits of using N95 mask to prevent serious emerging infectious diseases should be weighed against potential respiratory consequences associated with extended N95 respirator usage.”

“Contamination by respiratory viruses on outer surface of medical masks used by hospital healthcare workers”

pubmed.ncbi.nlm.nih.gov/31159777/

“Background: Medical masks are commonly used in health care settings to protect healthcare workers (HCWs) from respiratory and other infections. Airborne respiratory pathogens may settle on the surface of used masks layers, resulting in contamination...

The main aim of this study was to study the presence of viruses on the surface of medical masks.”

“Conclusion: Respiratory pathogens on the outer surface of the used medical masks may result in self-contamination. The risk is higher with longer duration of mask use (> 6 h) and with higher rates of clinical contact...

Protocols on duration of mask use should specify a maximum time of continuous use, and should consider guidance in high contact settings. Viruses were isolated from the upper sections of around 10% samples, but other sections of masks may also be contaminated...

HCWs should be aware of these risks in order to protect themselves and people around them.”

So I have provided 9 studies, many of which are meta-reviews of the literature on the efficacy or lack thereof of masking along with 4 studies indicating potentially negative health effects from wearing them.

This is but a small sample size of the scientific literature that exists proving unequivocally that the use of masks to limit viral spread of respiratory viruses is not a viable intervention and in fact can make matters worse when it comes to viral spread..

and the health of the wearer. Ask yourself, in light of all the evidence against masking, why do governments and health professionals continue to push this unscientific, harmful, and Orwellian agenda on the world?

Loving the response. It has inspired me to do this on another topic.
