Dr. Callan White, a dentist and national spokesperson for the Academy of General Dentistry, told us the video’s claim required “a few hops”. There is no scientific evidence that children breathe exclusively through their mouths when wearing masks, he said, and they do so long enough to mirror those of children with chronic mouth breathing.

“Kids with this condition can’t breathe through their noses at all, or very little, all the time. This condition creates the most harm at night when the child is sleeping,” he says. “There was a significant difference in the frequency and duration of the habit” of mouth breathing due to wearing a mask.

False claims about masks cause ‘bacterial infections’

Request: Nepute also erroneously claimed that “oh, by the way, that was the #1 thing that killed people during the 1918 Spanish Flu. Not viruses, but bacterial infections. These masks are causing this.”

Truth: In 2008, researchers at the National Institute of Allergy and Infectious Diseases published One research found that most deaths from the 1918 influenza pandemic could be attributed to secondary bacterial pneumonia after get the flu.

“Pneumonia is caused when bacteria that normally reside in the nose and throat enter the lungs through a pathway created when the virus destroys the cells lining the bronchial tubes and lungs,” says the National Institutes of Health. in one release research explanation.

So it is wrong to assume that the flu is not linked to those deaths. Furthermore, that study did not mention masks.

Gas detector ‘testing’ gives flawed conclusion

Request: In one video, Jeff Neff – a fireman and district council president in Sewickley, Pennsylvania – used a gas level detector to hypothesize that masks reduce oxygen levels to dangerous levels.

Truth: Thomas Fuller, a professor of health sciences at Illinois State University who reviewed the video for, told us that Neff had wrongly measured his own exhaled breath. Fuller said the oxygen molecules are small enough to pass through such masks when the wearer inhales.

Fuller, a member of the American Association of Industrial Hygienists, said: “He was completely misinformed and unqualified” to conduct such an examination.

MSA Safety, the is a manufacturer of equipment used by Neff – a ALTAIR 5X . Multi-Ray Detector – also told us that their product was “not designed for the use shown” in the video.

Misleading claims about ‘higher pollution risk’

Request: In a viral video – that received hundreds of thousands of views on Facebook and YouTube, before later removing it for violating the platform’s community standards – Ben Swann, a former television journalist, claims “improper use of a mask actually puts you at greater risk of contamination,” citing “a study also conducted in 2020… by a group of researchers in Hong Kong.”

Truth: this is a review among previously completed studies, not a new one, and it mainly looked at the effectiveness of different methods – including mask wearing, hand hygiene, covering coughs and sneezes , and cleaning surfaces – how will the pandemic flu respond.

The possibility that improper use of a mask could put someone at risk of contamination is addressed in a sentence in the article, citing interim guidance from World Health Organization to solve H1N1 pandemic in 2009. The two-page WHO article doesn’t explain what that caution is based on, but it does outline the best practices for wearing masks in public.

“If masks are worn, proper use and disposal is essential to ensure their potential effectiveness and avoid any risk of transmission associated with improper mask use,” such as touch the mask or reuse the disposable mask, WHO advises.

2015 study doesn’t support risk claims

Request: In his video, Swann also cites a 2015 study as evidence that masks increase the risk of contamination, saying: “Wearing a mask not only won’t stop the spread of the virus, it can also put you at risk. higher chance of contracting the virus”.

Truth: Again, this research did not view masks as source control in slowing the spread of the virus, which is why the CDC recommends wearing them. It looked at the effectiveness of masks in keeping healthcare workers from getting sick. It didn’t include a group that didn’t wear a mask, so it couldn’t say if cloth masks could provide more protection.

Research has found that “[m]Remaining, reusing cloth masks and poor filtration can increase the risk of infection. “But it says”[f]Urgent research is needed to inform the widespread use of cloth masks globally. ”

In addition, the authors of that study released a statement this year to clarify questions about their 2015 findings related to COVID-19. They explain that, in their study conducted in Vietnam, cloth masks may not have been washed enough, and the effectiveness of masks may vary depending on the material and number of layers used.

Raina MacIntyre, who served as the lead researcher on that study, clarified to in an email, “The study’s findings cannot be translated to the general public or to all masks.” She added, “There is also the issue of source control, which aims to prevent external transmission from an infected person. Face coverings provide a physical barrier. ”

People wearing masks cannot infect themselves with SARS-CoV-2

Request: In a fake documentary called “Plandemic”, Judy Mikovits, One former chronic fatigue researcher, falsely suggested that people wearing masks could infect themselves through their airways. “You’re sick with your own reactivation of the coronavirus, and if it’s SARS-CoV-2, you’ve got a big problem,” she said.

Truth: Experts tell us the implication that breathing through a mask alone could lead to self-infection is inconsistent with science. Lisa Brosseau, an expert in respiratory protection and infectious diseases, said the virus “requires living cells to replicate”.

“There’s nothing magical about our breath that can ‘reactivate’ or ‘reactivate’ the virus,” Brosseau said.

Misrepresentation of Government Guidelines

Misrepresentation of mask authorization on public transport

Request: Unreliable websites and a popular YouTube video spread the false claim that the CDC had made a “requirement” that people using public transportation must wear two masks.

Truth: CDC issue an order on January 29 “required people on public transport or on the premises of transportation hubs to wear face coverings to prevent the spread of the virus that causes COVID-19.”

CDC order For riders on public transport, “mask” is defined as “a material that covers the wearer’s nose and mouth, excluding face coverings”. A caption adds: “The mask can be manufactured or homemade and must be a solid material with no openings, exhalation valves or perforations.”

CDC’s guidance issued with the order stating that cloth masks, among other attributes, “must be made of two or more layers of tightly woven breathable fabric.” But a mask “made of two or more layers” is not like two masks as the video and title claim.

Misrepresenting FDA’s EUA on non-surgical masks

Request: ONE meme claims that masks are not effective against COVID-19, citing a warning label required by the Food and Drug Administration for non-surgical masks.

Truth: On April 24, 2020, the FDA issued a emergency use authorization for non-surgical masks that are “allowed for use only by the general public and health care workers as source control” – meaning “prevent the transmission of infection through a person’s respiratory secretions produced when speaking, coughing or sneezing. “Non-surgical masks used by medical personnel are not allowed to become personal protective equipment.”

The EUA requires that manufacturers of non-medical respirators marketed for use by the public must make it clear to consumers that the respirator is not intended for use in a medical setting. The memes twisted the warning required by the FDA to claim that the mask didn’t work at all.

Distorted statements about the increased risk of COVID-19

Request: In his video, Nepute also cites “Ontario public health officials” to state that “the public’s use of face masks may be linked to … COVID-19 increased (risk) theory- 19.”

Truth: It’s a reference to a september document issued by Public Health Ontario describing what the agency knows about using masks to control the spread of coronavirus – including benefits that Nepute did not mention.

Instead, Nepute only participated in part of the document, which read: “Public use of masks may be associated with a theoretically high risk for COVID-19 through reduced exposure to physical distancing and self-pollution.”

That means people wearing masks may not maintain a physical distraction. But that’s why health officials continue Advise that a mask should be worn beside, not as a substitute for looking away.

And self-pollution “referring to evidence that shows the frequency of face-to-face behavior in general,” Public Health Ontario told us.

The agency said “the view of ‘elevated theoretical risk’ is taken out of context.”

The PHO told us: “If the outside of the mask becomes contaminated, there is a theoretical risk that touching the mask and then touching the face could lead to exposure to the virus… it is important to minimize that. give birth frequently.
