Why do some people still think that face masks don’t work to protect them and others against COVID-19 infections?
The usual suspects…
Did a Doctor Prove That Face Masks Don’t Work?
Of course, most people understand that face masks work well to protect us from the SARS-CoV-2 virus and COVID-19 infections.
“Face masks are a simple way to help decrease coronavirus transmission and save lives.”Which type of face mask is most effective against COVID-19?
Sure, not all types of face coverings are created equal, but if you are wearing a face mask when you can’t social distance, then you will help to reduce the spread of SARS-CoV-2.
And no, despite his claims and video on YouTube, Dr. Ted Noel, a retired anesthesiologist, did not prove that face masks don’t work!
What did he prove?
If you are vaping and exhale through a poorly fit face mask, then, not surprisingly, the “vape smoke” is going to find a way around your mask!
Will it go through your face mask ?
Again, not surprisingly, it depends on the type of face mask.
In Ted Noel’s little experiment, you can see that his cloth mask didn’t perform very well.
Interestingly, someone else had already done this face mask experiment and got widely different results!
Doctors Who Proved That Face Masks Do Work
And these results that face masks work have been shown in much more sophisticated experiments using high tech equipment, including high speed cameras and laser light scattering.
These experiments confirm that face coverings can block aerosols and droplets when we cough, sneeze, and breath. And since viruses like COVID-19 are carried on these droplets, they prove that masks work.
Well most face masks…
To make sure your face mask works effectively, you should:
- use a face covering made of at least two layers of a washable, breathable fabric
- avoid face masks with valves
- use a properly fitting face mask instead of a neck gaiter or bandanna
- avoid face coverings made with fleece
- wash your cloth face mask
And don’t listen to or share misinformation from folks pushing propaganda about COVID-19.
“Among 139 clients exposed to two symptomatic hair stylists with confirmed COVID-19 while both the stylists and the clients wore face masks, no symptomatic secondary cases were reported; among 67 clients tested for SARS-CoV-2, all test results were negative. Adherence to the community’s and company’s face-covering policy likely mitigated spread of SARS-CoV-2.”Absence of Apparent Transmission of SARS-CoV-2 from Two Stylists After Exposure at a Hair Salon with a Universal Face Covering Policy — Springfield, Missouri, May 2020
