What causes cold sores? In this excellent article, you will discover what causes cold sores in the majority of folks already infected with the herpes virus.
The short answer to what causes cold sores is the herpes simplex virus.
Of all those infected, about a third will never get a cold sore. The virus will stay dormant deep in the root cells of the facial nerves. The other two-thirds of us will get repeated outbreaks.
If the herpes virus decides to replicate, it will move to the surface and enter your cells there. This destructive virus then forces the cells to create new virus particles.
As the cells fill up with new virus copies, swelling of the tissue occurs. Then the cells burst open. This releases the new virus and creates your cold sore.
