Scientific Evidence that Masks Reduce SARS-CoV-2 Transmission:
Peer Reviewed and Published papers

This painting shows a cross section through a small respiratory 
droplet, like the ones that are thought to transmit SARS-CoV-2. The
virus is shown in magenta, and the droplet is also filled with 
molecules that are present in the respiratory tract, including mucins
(green), pulmonary surfactant proteins and lipids (blue), and
antibodies (tan).

There are now a number of peer reviewed published scientific papers that demonstrate that wearing masks works to reduce SARS-CoV-2 Transmission.

Peer Reviewed and Published Scientific Publications

Peer reviewed means that the editor probably sent the paper to at least two people in the field who are competent to read, understand and strongly critique the paper. The editor gets the two reviews and makes a decision: accept, send back to the authors or reject. The author gets the reviews, which are anonymous so the authors do not know who is reviewing their paper (this prevents retaliation but also could expose the author to abuse by the reviewers). The authors revise the paper and send it back or to another journal. This process repeats until the paper is accepted or rejected. Peer review invariably improves the quality of scientific papers. Junk and unsubstantiated claims are weeded out most of the time. This does not mean that the final publication is correct. Further papers in the scientific literature will eventually usually come to an agreement about the results.

Published means that a respected journal has accepted and printed the paper either physically or online. A respected journal will usually have been publishing for many years.

Scientific means that the paper contains science, based on experiments or analysis of published data. Guesses are called "hypotheses" and speculation might be given in the Discussion at the end of a paper but will be clearly stated as hypotheses and speculation.

These measures should be combined and complemented by additional interventions (e.g., physical distancing, hygiene, testing, contact tracing and vaccination) to maximise benefit.

  49. PEER REVIEWED PUBLISHED PAPER: Masks During Pandemics Caused by Respiratory Pathogens--Evidence and Implications for Action JAMA Network Open. Published: October 31, 2023

    Question During the COVID-19 pandemic, what has been learned about whether face mask use is associated with lower transmission of SARS-CoV-2 in community settings, and how has it been learned?

    Findings Literature review revealed many high-quality observational studies demonstrating the association of face mask use in the community and of mask mandates with reduced spread of SARS-CoV-2. Randomized clinical trials conducted during the pandemic provide limited information.

    Meaning Robust available data support the use of face masks in community settings to reduce transmission of SARS-CoV-2 and should inform future responses to epidemics and pandemics caused by respiratory viruses.

  50. PEER REVIEWED PUBLISHED PAPER: Impact of community mask mandates on SARS-CoV-2 transmission in Ontario after adjustment for differential testing by age and sex PNAS Nexus. Published: 12 February 2024
    After adjustment for under-testing, mask mandates emerged as highly effective. Community masking saved substantial numbers of lives, and prevented economic costs, during the SARS-CoV-2 pandemic in Ontario, Canada.

  1. PREPRINT: The Effects of Large Group Meetings on the Spread of COVID-19: The Case of Trump Rallies
    Conclusion of the paper (my emphasis):
    Our analysis strongly supports the warnings and recommendations of public health officials concerning the risk of COVID-19 transmission at large group gatherings, particularly when the degree of compliance with guidelines concerning the use of masks and social distancing is low. The communities in which Trump rallies took place paid a high price in terms of disease and death.
    and
    Applying county- specific post-event death rates, we conclude that the rallies likely led to more than 700 deaths (not necessarily among attendees).

    "Therefore, a preventive effect of HEPA filters against COVID-19 in kindergarten settings was not confirmed. Classic preventive measures, such as wearing of facemasks and frequent ventilation, remain of utmost importance in kindergartens to curb COVID-19 contagion."

Example Scams and Lies

  1. The Rachel Maddow Show. "It is not true that 85% of people who wear masks get Covid. That is absolutely bunk." (See the video)
    • Original CDC SCIENTIFIC report: https://www.cdc.gov/mmwr/volumes/69/wr/mm6936a5.htm
    • Original scam NOT SCIENTIFIC report: https://jordanschachtel.substack.com/p/cdc-85-of-covid-19-patients-report
    • Explanation of how the SCAM worked as given in the comments on that page:
      Alanso18 min
      The report findings are being distorted to support the dangerous whining about mask weating[sic]. The study specifically pointed out that all of those testing positive had participated in activities where mask wearing was not possible or adhered to, such as dining out (50%) gymn, church, bars, etc. In other words, NOT wearing a mask on those occasions caused the infection, despite wearing 85% wearing masks regularly outside tyese activities. Distorting facts is a common propoganda technique that fools those who allow others to define information for them, rather than investigate for themselves. Read the CDC report, it in no way states that masks are ineffective.
