Spreading Cold Sores: Are Cold Sores Contagious?

Protect yourself from the spread of cold sore with these top tips

The first question people ask is ‘Are cold sores contagious?’. The answer is yes. HSV-1 is as easy to spread as it is tough to fight.

So how do cold sores spread? The cold sore virus can be spread through skin-to-skin contact. It sneaks into your body through the mucous membrane in your mouth or damaged skin. It then remains dormant inside a group of nerve cells located at about the level of your temple until a cold sore trigger awakens it.

The cold sore virus cannot spread beyond the lip area


HSV-1 is a form of the herpes simplex virus that usually affects the lips, but can also affect cheeks, nose or mouth or rarely even spread to the eyes or genitals.
