Why don't cold sores spread to the opposite lip?

IB Chemistry  asked the Naked Scientists:
   
Hi,

This seems to have stumped the science teachers here where I work

Why can a cold sore transfer easily to other parts of your body (and other people too), but does not seem totransferfrom one lip to the other?

Love the show, listen to every one !
