Fact Check: America's Frontline Doctors Did NOT Prove Their Claims That Masks Don't Work Docs w/o data

Did an anti-mask group of doctors prove its claim that masks are "irrelevant" to the prevention of COVID-19? No, that's not true: The 19 people in white lab coats who stood in front of the U.S. Supreme Court to make the claim did not provide a citation to published research papers nor supply records to support their claim that masks are "irrelevant." But medical journals and the U.S. Centers for Disease Control and Prevention supply multiple citations to clinical and lab research that show data and methods that prove mask-wearing slows the spread of COVID-19.

The claim was made in a video (archived here) posted as part of an October 18, 2020, report by One America News Network under the title "Doctors Speak Out Against Masks." It opened:

A group of doctors from around the country known as America's Frontline Doctors gathered in Washington to speak out against some of the extreme measures taken against COVID-19 thus far. One America's Christina Bobb has more.

Here is how the article and video appeared at the time of writing:

Dr. Simone Gold, founder of America's Frontline Doctors, seen at the microphone in the screenshot, led off the Sunday, Oct. 18, 2020, news conference in front of the U.S. Supreme Court building. She said:

The facts are actually not in dispute. Masks are completely irrelevant in blocking the SARS-Cov-2 virus."

Public health officials reject Dr. Gold's statements and provide peer-reviewed studies to support universal mask-wearing to slow the spread of the COVID-19 pandemic. In August 2020, two months before Gold's claim was made, Lead Stories identified 19 studies that disprove mask skeptics' claims, which we published in a report entitled: "Face Masks DO Work. Period."

Here are some of the major medical validations of mask-wearing to slow the spread of COVID-19:

The Journal of American Medical Association: In an editorial, one of America's leading journals of medical science spoke out in favor of mask mandates and against those who claim without evidence that masks are ineffective:

...this study provides critically important data to emphasize that masking helps prevent transmission of SARS-CoV-2...Now, there is ample evidence that persons without symptoms spread infection and may be the critical driver needed to maintain epidemic momentum."

The CDC: In one of its weekly updates on the pandemic battle, the nation's public health agency said two studies support mask-wearing as an effective way to reduce the spread of COVID-19 infection.

This review included two case studies out today, one from JAMA, showing that adherence to universal masking policies reduced SARS-CoV-2 transmission within a Boston hospital system, and one from CDC's Morbidity and Mortality Weekly Report (MMWR), showing that wearing a mask prevented the spread of infection from two hair stylists to their customers in Missouri."

The World Health Organization: Which early in the pandemic cautioned against public overuse of masks until medical professionals and other front-line workers had enough, reversed that stand based on new findings about disease transmission and on the availability of masks.

At least one California hospital has taken steps to distance itself from Dr. Gold's anti-mask and pro-hydroxychloroquine statements:

Simone Gold, MD, is not credentialed as part of the Centinela Hospital Medical Staff, as she resigned her position here a number of years ago...Further, her practice is not located on our campus, nor is she affiliated with any medical group related to the hospital."

Similarly, Dr. Jeanne Marrazzo, the director of the University of Alabama at Huntsville's Division of Infectious Diseases, has spoken out against the public statements made by another member of Gold's organization, Dr. David Calderwood, of Huntsville, Alabama, who has joined Gold in saying hydroxychloroquine is an effective treatment for COVID-19 and that masks aren't needed. Marrazzo told a Tampa television station that the remarks by Calderwood and other members of America's Frontline Physicians in a July 2020 video were "irresponsible and, frankly, really despicable."

We have excellent, high-level evidence from clinical trials showing that (hydroxychloroquine) doesn't work and that it has some bad side effects...These are people who are posing as physicians, who to me are violating the Hippocratic Oath, which is first, do no harm...By getting up there, and distributing information, with the badge of their white coats, and their degrees behind them, to me it's one of the few things that really upsets me. It's really unacceptable."

Here are other studies the CDC lists as supportive of mask-wearing as a preventive measure:
