Question about the transmission of parvo?

I'm planning on going to a get together tonight. Two friends of mine who are coming, who will undoubtedly hug me whether or not I'm expecting it, have a puppy who just survived parvo. They don't live at the house I'm going to and the puppy will not be there, but could I still get germs on me from them and carry them home? I have a dog is a fully vaccinated adult and thus cannot (or is very unlikely to) get parvo. However, I know that it's possible that she can get it in her system and transmit it through her feces to other dogs, and we have neighbors with a puppy. My question is: what are the chances that I bring home and give my dog the virus? I don't want to think of her giving the puppy parvo if it touches her feces. Am I being a responsible person if I go?
