Now that untold have died, millions of citizens rights violated, hundreds assaulted, prosecuted, jailed, and fired for being smarter than democrats and the cancel culture, we find out what we knew all along. We were right.
Cloth masks useless, experts say in omicron messaging shift
by Cassidy Morrison, Healthcare Reporter | | January 21, 2022 06:15 AM
Prominent public health officials have increasingly highlighted the limitations of cloth face masks, pushing for more effective respirator masks such as N95s as omicron engulfs the United States, a shift in messaging from earlier in the pandemic.
Officials encouraged the use of cloth masks in the spring of 2020 as a desperate measure to slow the spread of COVID-19 after previously recommending against masks and continued to boost them in the months after. Now, though, more experts are saying that the masks are not helpful.
“Cloth and surgical masks do absolutely nothing for protection from ambient virus,” said Chad Roy, a microbiologist at Tulane University School of Medicine, referring to the virus spreading through the air. “All this song and dance of wearing cloth masks with some presumption that you're being protected from ambient virus is completely and positively 100% counter to how masks and respirators work.”
Evidence of the N95’s superiority to the cloth mask has been well-documented. In 2015, for example, before the onset of the pandemic, scientists from Australia, Vietnam, and China concluded that healthcare workers “should not use cloth masks as protection against respiratory infection. Cloth masks resulted in significantly higher rates of infection than medical masks, and also performed worse than the control arm.”
“The use of an N95 does give you some protection in a bidirectional manner, meaning that if you're using an N95 without a one-way valve for exhalation … you're protected from not only ambient aerosol of a particular size, as well as exhalation if you are ill, so it does double duty in that regard,” Roy said.
