It has been 45 years since I took microbiology in college, but I remember some things. These medical masks are to keep bacteria from getting into an open wound, like in surgery. You can see a bacteria under a regular microscope. An independent virus particle, called a virion, can only be seen under an electron microscope. Stand a match box car beside a train box car, and that is how a virus compared to bacteria looks. A medical masks has about as much of a chance of stopping an air borne virus partical as a chain link fence has in stopping a mosquito. A mask to stop the spread of a virus would have to be made out of Saran wrap. Remember when the China virus first hit in 2020? And the protocal was to always wash your hands, and any surface you may touch...like door handles, shopping cart handles, etc.. Don't touch your face, mouth eyes, etc? The first suggestion about a mask was IF you have the China virus, wear a mask when you go out, to stop mucus, saliva etc from spraying out on to surfaces if you went out while you had it, when you cough or sneeze. After a few months, the protocal changed to " if you have it, stay the hell at home away from other people. I have seen idiots, mostly younger millenials, wearing a mask alone in a car! I always told dr offices and urgent care clinics that if their doctors and nurses did not KNOW it was foolish and ineffective to wear one...if they had forgotten their pre-med microbiology 101... then I was leery of what all else they may have forgotten, and didn't think I trusted them to be able to treat me. I would say: " I don't have it so need in wearing one. If you have it..which I can only assume you do since you have a mask on... then you need to go home til you are well." I was never prevented from seeing one.
