I promise you, you can't get sick from "droplets getting in my hair and infecting me". Nor can you get sick from touching something infected. Just don't put your hands in your mouth/eyes/ears/nose. Wash your hands when you get home and before you eat, don't let anyone sneeze in your face, and you'll be good.

I'm not trying to be mean, but the above seriously sounds like a kind of mental illness. You should see someone.
