what type of herpes simplex virus causes cold sores?

Type 1 more common: Cold sores on or near the lips are due to recurrence of herpes type 1 or 2. Herpes viruses, after the initial infection, live in a person's nerves and travel down the nerves to the surface to form blisters that break open, spreading more virus. Type 1 is more common on the lips, and type 2 more common on the genitals. With people engaging in oral sex, either type can be in one or both locations.
