Tricky: 58% of people in the us have the virus that makes cold sores. Not everyone will have outbreaks. Cold sore on the lip is contact transmitted. The best way to avoid getting in the first place is not kiss or touch anyone or use towels, utensils or drink from cups who has it. Unfortunately, it can still be transmittable when an outbreak is not obvious.

Clarify question: Sounds like you have had a cold sore. How to manage recurrence? Protect from sun with frequent use of chapstick with sunscreen. Take valacyclovir 2 grams at the first tingling (prodrome) of next attack. Crucial to take immediatly so you need to always have it handy. If your sister's wedding is coming up & you need to kiss everyone take valacyclovir or Acyclovir every day for a week before.
