Cold sores are small fluid filled blisters, also known as fever blisters, that are develop on or near the mouth and the lips. They are caused by the herpes simplex virus (HSV-1). Cold sores are highly contagious and are spread by coming in close contact with secretions from the blisters or sharing utensils or other personal hygiene items with an infected person. It is important to keep in mind that the virus can spread even when an infected person does not have a cold sore.
