It's in the excerpt.
“Researchers from Asan Medical Center, University of Ulsan College of Medicine, Seoul, South Korea instructed 4 patients with COVID-19 to cough 5 times each onto a petri dish while wearing the following sequence of masks: no mask, surgical mask, cotton mask, and again with no mask. Mask surfaces were swabbed with aseptic Dacron swabs in the following sequence: outer surface of surgical mask, inner surface of surgical mask, outer surface of cotton mask, and inner surface of cotton mask. The researchers found SARS COV-2 on all surfaces. These findings suggest that recommendations to wear face masks to prevent the spread of COVID-19 may not be effective. “
This is truly idiotic!!
So they found that the virus was on the surfaces of the masks. Isn’t that what the masks are supposed to do??
And how did they check the effect of no-mask? And what was the purpose of the petri dish if all they checked was what was on the masks?
I’m either missing something or this is the stupidest test on record!
