Dear 100 Hour Board,
Do germs travel on their own? I know if I sneeze on my hand and open a door that the germs travel from my hand to the doorknob, but what about if I don't do anything. If my dog poops on the carpet in one corner of the room, will the germs spread to the other side? Could it travel up the legs of the furniture that the dog pooped next to? If I walk outside in socks, can germs from the ground travel through them and onto my feet? Does touching one part of the faucet handle before I wash my hands and one after I wash them make a difference?
Germs can certainly travel on their own, they can travel through the air or on dust or water particles. It's common to have airborne germs and diseases transmitted by air. However, here's the thing. Germs are transmitted to a much higher degree by touch. In your doorknob example, a sneeze would certainly get something on the doorknob without touching it, but touching it would transfer many many more microbes than the air alone. There are germs everywhere, but mostly in amounts that you don't need to worry about, because your body will easily take care of it.
As far as germs moving on a solid object, the principle is pretty much the same. It's highly unlikely that germs will travel up the legs of furniture or to another part of a faucet, but even if it were to happen, the germs would be in a very very small amount, an amount to small to even worry about.
In short, thanks to air flow and water or dust particles, germs could certain travel around pretty much anywhere, but in amounts that are certainly way too small to worry about.
Keep it real,
