Herpes; cold; simplex; sores; ;
Cold sores are caused by a virus called herpes simplex virus (HSV). Cold sores are very common. About 20% of children will have been infected by the age of 5 years and about 80% of people will have been infected by the time they are adults.
After the first infection, the virus that causes cold sores 'hides' in the nerves of the skin (usually around the lips), and can cause new cold sores from time to time.
