   What causes cold sores on the mouth?

   • Cold sores on the mouth are mainly caused by the oral (type 1) herpes virus, but they can also be caused by contact with the genital (type 2) herpes virus. A healthy immune response usually combats it and prevents infection. Thus, people with weakened immunity are at higher risk of HSV infection and complications. X Research source

   Can a cold sore reappear on your lips?

   • This is unlikely. If you caught your cold sore on your lips, it might reappear elsewhere on your face, but it cannot reappear elsewhere on your body. You make antibodies in response to the virus, and they prevent you from spreading it to another area. They also make it unlikely that you will catch it again.

   Can cold sores be prevented?

   • It’s not possible to prevent infection with the herpes simplex virus or prevent outbreaks of cold sores. However, there are things you can do to minimise the spread of infection. Cold sores are at their most contagious when they burst (rupture), but remain contagious until they’re completely healed.

   How do you treat a cold sore?

   • You can buy electronic devices from pharmacies that treat cold sores with light or lasers. You may find these helpful, but there's not much evidence to confirm they work. If you regularly get cold sores, use antiviral creams as soon as you recognise the early tingling feeling. They do not always work after blisters appear.
