To Touch or Not to Touch!

That is my Dr's office door, thank God I didn't touch it, I wore my gloves and took them home and washed them.  I am so paranoid that I even bring my own pen.  It was horrible inside, a room full of adults and children coughing and  sniffling plus the lady next to me vomiting into a bowl.  Yeah, I definately don't want that!  I felt so bad for her, how unbelievably uncomfortable.  So when faced with the Dr's office door do you touch or not?
