# What are cold sores?

Cold sores are a common viral infection in both men and women. 

It is most commonly caused by the herpes simplex virus type 1 (HSV-1), however, it can also be caused by the herpes simplex virus type 2 (HSV-2), which is usually more associated with genital herpes.

The herpes virus is transmitted by close contact with an infected person, usually through broken skin, and generally through sexual activity. Both viruses are contagious, even when symptoms are not visible, so it is important to treat the virus effectively to reduce the length, severity and spreading of the outbreak.

There is currently no cure for cold sores, and outbreaks can be frequent, causing sores and blisters around the mouth and facial areas. However, symptoms can be easily managed with antiviral medications and topical creams.
