Common Facts about Cold Sores
- Cold sores are caused by a common virus which affects an estimated 8 out of 10 people.
- Cold sores are NOT something that you get from being dirty, careless or going through puberty – they are caused by a widespread virus that is as easy to catch as the flu.
- Once you catch a cold sore, the virus resides inside the body permanently (just like every other virus) and for some people this can mean that a cold sore may pop up from time to time.
- Over 75% of adults have been exposed to the cold sore virus at some time in their life.
- Approximately 30% of people have recurring cold sore symptoms
- The rate of cold sore symptoms coming back is typically once every three months, or four times a year. However many people very rarely experience symptoms (or never experience them) and some people experience them more regularly than this.
- The body immune system is the key factor in the defence against the virus and recurring outbreaks.
- It can take a few days for a cold sore to develop when you first contract the virus, usually between 2 to 20 days after contact.
