Cold sores -- you might hear them called fever blisters -- are proof that life can be unfair. Some people get them, others don’t. If you get them, don't worry. There are ways to treat and prevent them.
Despite the name, that isn’t what causes them. The herpes simplex virus type 1 (HSV-1) is most often the cause. You get it from contact with an infected person’s skin or body fluids. The virus damages your skin as it reproduces. That leaves behind weepy sores that last about a week. Between outbreaks, HSV-1 hides inside nerve cells, so it’s never completely cured.
About two-thirds of us have been infected with the HSV-1 virus. It usually comes via well-meaning kisses from relatives or romantic partners. So why do only an unlucky few get cold sores? The answer may be in your genes. Most of the people who get cold sores share genes that may relate to how HSV-1 acts in your body. This could be what causes outbreaks.
