Both surgical and cotton masks were found to be ineffective for preventing the dissemination of SARS-CoV-2 from the coughs of patients with COVID-19. A study conducted at two hospitals in Seoul, South Korea, found that when COVID-19 patients coughed into either type of mask, droplets of virus were released to the environment and external mask surface. A brief research report is published in Annals of Internal Medicine.
During respiratory viral infection, face masks are thought to prevent transmission, leading health care experts to recommend their use during the COVID-19 pandemic. With a shortage of both N95 and surgical masks, which have been shown to prevent the spread of influenza virus, cotton masks have gained interest as a substitute. However, it is not known if surgical or cotton masks worn by patients with COVID-19 prevent contamination of the environment.
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.
And it ends with the universal research study conclusion...”Further study is needed...”
IOW, “send more money.”

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!
Not doubting but source?
They did test the petri dishes.
The testing wasn’t stupid.
The conclusions, however...

You might want to consider augmenting that wonderful collection of "prep" supplies, with one each of these effective solutions for opposite kinds of surprises, relating to matters of the royal throne...
This was a few days ago. I’ll need to look for it.
If I recover the data, I will post it here.
The only known effective PPE is a face sealing, non-porous, chemically inert, flexible mask that filters air through a HEPA 13 or better filter without side leakages.
ROFLOL!!!!!!!!!!!!!!!!!!!
I’ve known that as a virus is too small to be stopped. The mask might stop the sputum from a cough going out or coming in, but not a virus.
I cannot tell you how many times,..I've been "fit" tested....
It’s a great toy! The kids love it!
Excellent observation.
My daughter just gave me a couple of older 3M n-95 masks.
I wore one for the first time when I went to a business to sign and pay for my tax filing.
Turns out I am allergic to the straps and have a very itchy neck now. -Tom

Even if the snot penetrates to the outside of the mask, that is a whole lot better than it crossing the room.
Nice. :)
This strikes me as not very useful research.
