I agree with Beady. Use common sense and know that unless your immune system is compromised in some way that it is building up immunity constantly.

I remember that my cousin got polio and the rest of us kids who saw him a lot got awful sore throats and stiff necks. (those were symptoms) The cousin who got it and thankfully survived without disability was the child of the aunt who was very very careful of germs and kept him in a LOT. Our doctor told us that we who got the sore throats at the same time had probably had immunizing cases of Polio.

You can become obsessed or just use common sense, wash your hands, and when you don't, the exposure may be helping you. There is no use worrying yourself to death.
