The virus is very very small. The N95 doesn’t filter 0.3 micrometers. However the virus when coughed or sneezed out of an infected host is suspended in water droplets that are much larger than 0.3 micrometers. The N95 is very nearly 100% effective at catching those droplets. The outside of the mask is now contaminated and must be discarded safely. For the vast majority of people who were infected with N95 mask usage were contaminated while removing the mask. You must not touch the outside of the front of the mask while it is removed. There is specialized training in the proper donning and doffing procedure for PPE.
I don't dispute any of that. However, it is being mentioned, and bantered about, that merely breathing is possibly spreading this. Hell, Dr. Birx herself alluded to that possibility in one of Corona Task Force pressers.
And so I say again, when are the medical community going to get on the same page with all this?
Also, since some of you guys are in the medical field, let me put this out there for consideration. If everything you smell with your olfactory receptors is molecular, then those odorants, like a virus are extremely small. Can you smell certain things while wearing an n95 mask? Of course you can. The stronger the odorant, the proportionate the size of the molecule, or abundance thereof.
Now I don't know how small the molecules of certain deodorizers or disinfectants are, but I know you can smell them through an n95 mask at times. Would you conclude that if you can smell these molecules, that you are also breathing them into your nasal passages and thus associated mucus membranes?
