Have you heard of a study that showed masks don’t work against viruses? It’s disinformation



The Associated Press reviews some of the most popular but completely bogus stories and visuals of the week. These are fakes, even though they have been widely shared on social media. Here are the facts:

CLAIM: A 2018 study that looked at the effectiveness of N95 masks over medical masks found that masks do not stop the spread of viruses.

FACTS: The study found that N95 masks and medical masks are just as effective in protecting against viral infections and respiratory illnesses – not that masks don’t work.

The trial followed groups of healthcare workers who were randomly assigned to wear N95 or medical masks, also known as surgical masks, when in close proximity to patients with respiratory illness or flu. He looked at the health outcomes of these health workers at 137 outpatient care sites over four influenza seasons.

Derek Cummings, professor of biology and infectious disease epidemiologist at the University of Florida, said the study builds on previous research that has shown that masks are effective in preventing the spread of viruses.

“The study was not designed to assess whether N95 masks are working or not,” he said. “What we were trying to do was say we know the N95s work. We don’t know how much better they are than medical masks.”

The to study, which first appeared online in 2018 and then was published in the Journal of the American Medical Association in 2019, determined that the two types of masks worked equally well. One line in the study’s conclusion reads in part: “Neither N95 nor MM resulted in superior protection.” ”

Social media users shared screenshots of this section and falsely claimed it was proof that masks didn’t work. Trish Perl, chief of the division of infectious diseases and geographic medicine at the University of Texas Southwestern Medical Center, also co-authored the study. Perl said she was mortified when she saw misinformation about the study circulating online.

“We found that there was no difference between wearing a respirator and wearing a medical mask in this study,” she said. “We didn’t say the masks didn’t work or that the N95 masks didn’t work.” Since the start of the pandemic in 2020, disinformation around masks has circulated online. Health officials, including the United States Centers for Disease Control, recommend masks to prevent people infected with the coronavirus from spreading it.

No, an employee strike did not force Denver airport restaurants to close

CLAIM: The owner of five restaurants in Terminal C at Denver International Airport told employees they need to get their COVID-19 vaccine before November 1 or they will be fired. None of the cooks, dishwashers, bussers or hosts showed up for work, so there was no restaurant open in Terminal C. The owner immediately sent an email reversing the vaccination warrant.

FACTS: This week, social media users baselessly claim that employees at the Denver airport restaurant canceled a vaccination warrant by not showing up for work. “Denver Airport,” read a tweet on Thursday, shared more than 5,000 times.

“The owner of 5 restaurants in Terminal C issued a warrant on November 1 or gets fired. None of the cooks, dishwashers, bussers and hosts showed up for work. So there was no restaurant open in Terminal C. He immediately sent a warrant cancellation email.

The message in the tweet, which was later deleted, circulated widely on Twitter, Facebook and the Telegram messaging app, although it did not provide any details or evidence that the incident occurred. In fact, that didn’t happen, according to Alex Renteria, public information manager for Denver International Airport.

“We have not had any strike by dealership workers, and no restaurant in Hall C has been closed outside of its normal business hours,” Renteria said. “We can confirm that this is false information.”

Earlier this month, Denver airport concierges staged a one-day strike for higher wages, according to the local the news. And the security guards Recount a local television station this week, they voted in favor of the strike for the same reason. These work actions did not appear to be related to vaccine requirements.

There is no airport-wide vaccination mandate, Renteria said, and companies with retail stores in the airport individually decide whether or not to require their employees to be vaccinated. Three different companies that appear to own restaurants in Hall C at Denver Airport – Tastes on the Fly, Paradies Lagardere and Edible Beats – did not respond to email requests for comment on their vaccination policies.
