Cold sores are also referred to as fever blisters. They are tiny, fluid-filled blisters and usually occur in patches on or around your lips. Once these blisters burst, a crust forms over them.
Cold sores can be transmitted from one person to another by close contact like kissing. It is caused by the herpes simplex virus (HSV-1) that is closely related to the one that causes genital herpes (HSV-2). Both these viruses can be easily spread by oral sex. Cold sores are contagious, irrespective of whether they are visible or not.
Although cold sores can heal on their own, they may take up to four weeks to go away completely.
