You Probably Have the Virus that Causes Cold Sores

As many as 90 percent of people have antibodies to HSV-1 by the time they become adults, meaning they were exposed to the virus at some point in their lives, usually during childhood. They may have been exposed to the virus through close contact with a child who had it or by handling an object that contained the virus, like a toy that had been in the mouth of another child. In many people, the virus remains dormant, never producing any symptoms. About half of those who’ve been exposed to HSV-1 go on to experience actual outbreaks.
