How do you get cold sores?

Cold sores explained

More than 80% of adult Danes carry herpes 1. Around 20% carry herpes 2. Most have been infected as children before they are 5 years old. Once you have been infected with herpes, you carry the virus in your nerves.  Here the virus lies dormant and erupts at different intervals. Many people only have their first outbreak and never notice the disease again, but about 20% have recurring outbreaks, most often 2-3 times a year. Some have fewer outbreaks and others are very troubled by frequent outbreaks. You cannot be cured of herpes and herpes cannot go away on its own.
