Rock your body back and forth really quickly, your head swinging right along with your torso. Feel a bit of a wind? It is so when you walk. A small current of air is created.
In this is a huge secret to fighting COVID-19.
From the small wind created by walking, small virus particles are swept around and away from your face. That little of a wind carries them away because they are so light. They don't quite get close enough to enter your body because the wind current sweeps them around you. I would suspect this is why we are more likely to contact the virus if just standing in one place with others for a substantial amount of time. Standing still enables the virus, as the air is stagnant and the particles float into contact with your face. Walking disrupts it, as a small wind is created to carry the particles around and away from your face.
So, what of the notion that wearing a mask only protects you from giving the virus away, not from getting it? I would say that it is wrong. When someone coughs or sneezes, they hurdle large projectiles into the air. You put on a mask, and those are caught before they hit you in the face.
But, more than keeping away the large projectiles, it is important to keep away the small particles that float in the air -- the small airborne particles emitted from just talking and breathing. They are the greater fear. The virus is spreading more from this fashion. Most of the transmissions are not from the projectiles, but from these small airborne particles that waft out of the mouth and nose when just breathing. They don't fall quickly and within six feet like the projectiles do. No, they hang in the air and float.
The small wind of a walk will help carry much of the virus away, but wearing a mask helps. Without the mask, the wind touches your face. So, even though many of the particles are being swept around and away from your face, some of that wind and thus some of the virus is touching your face. Put on your mask, and the covered part of the face will not fell any of that wind. If this wind cannot reach you, neither can the virus it carries.
