one time my cousin had an infected toe. he touched his toe with his hand and then stuck his finger in his mouth. after that he opened the fridge and touched other things with the same finger..
lol, i would not doubt it, especially since he stuck the same finger he used to touch his toe, right into his mouth. it was so gross to watch. and then afterwards he went to the fridge and started touching all kinds of items in there.
he probably passed the infection to his mouth! gross!
