I've heard various things...its called autoinoculation (self-infection).
"Inoculation and autoinoculation can occur by transferring the virus from one part of the body to another, usually via touching a sore with a hand and then touching another susceptible area, such as the mouth or eyes. This complication is more common during a first episode because of higher amounts of virus present during that time. Herpes is also more likely to spread to compromised epithelial tissue - skin that has suffered cuts, abrasions, scrapes, etc."
"In general, autoinoculation is very uncommon after the primary initial outbreak, because your immune system has been established against herpes simplex. If possible, avoid contact with the sores. Practice normal hygienic precautions, i.e. wash your hands with soap after touching your genitals, going to the washroom, etc."
