What are cold sores?
Cold sores, also known as fever blisters, are caused by two strains of the herpes simplex virus. Herpes simplex virus type 1 (HSV-1) is the main cause of oral and facial cold sores.
HSV-2, which tends to affect the genitals, can also affect the mouth and face if it is transmitted there.
The cold sore virus is most often passed on through kissing - or oral sex - when a blister is present.
