The virus doesn’t float in the air by itself, it’s suspended in tiny water droplets. Wearing a proper mask significantly reduces both the chance of breathing those droplets, and the chance of spreading them to others.
Why is that hard for you to understand?
“Wearing a proper mask significantly reduces both the chance of breathing those droplets, and the chance of spreading them to others.”
I keep asking, when the moisture dries out of the droplets, won’t the attached viruses that collect on the mask be easier to breathe in? It is like trying to stop a bb with a chain link fence.
I have worn masks around dust, and when the mask gets moisturized from your breath, it start to collect debris on the surface and makes breathing more difficult. You breathe harder, sucking in more [virus].
Then, their are your eyes wide open when you walk into a cloud of droplets that the person six feet in front of you just left hanging. The fastest way for a virus to enter your body is through the eyes.
An experiment shows that an N95 mask will stop a virus two inches when worn. The rest are measured in feet. I believe it said the type of mask you make for yourself as per instructions of the Surgeon General is four feet.
Because that is not true. Aerosol droplets are <2.5um in size. That is too small for any mask to catch. Either breathing in or out.
Cloth masks pass thru 97% of such droplets, and surgical masks 44%. There are references for this.
And, a single droplet contains enough virus to infect anyone. Masks are worthless, and CDC/WHO have known this for quite some time.
It isn’t. People aren’t wearing “proper masks”. Why is that hard for you to understand?
