How common are cold sores?

Cold sores are very common. It is estimated that 80% percent of the American population have been exposed to the Herpes simplex virus (which is the virus that causes cold sores).

An interesting fact is that although a person has been infected with the herpes and cold sore virus, they may not necessarily experience an outbreak. This is because some people's immune systems have the ability to completely suppress the virus.
