What causes cold sores?

Cold sores are common. They are small blisters that appear on the mouth and lips, caused by the virus, herpes simplex virus type 1 (HSV-1). Around 70% of people carry the virus that causes cold sores. Many are unaware they have it because they have no symptoms.

Cold sores can be easily passed on by coming in contact with someone who has them. They can be passed on with any skin to skin contact.

When you are first infected with the virus, you often will not have any symptoms. The first signs of a cold sore are tingling, itching, or burning feelings where the blister is starting to come through. Cold sores are contagious from when you first feel the tingling sensation until it has completely healed.

Sometimes, cold sores can be caused by the herpes simplex virus type 2 (HSV-2). This type of the virus is passed on by having sex with someone who has genital herpes. Genital herpes is a sexually transmitted infection (STI). It can be spread from the genitals to the mouth during oral sex.
