About Cold Sores or Oral Herpes

Advertisement

Cold Sores or Oral Herpes are small blisters, which are filled with fluid and develop on and around the lips. These lesions are commonly found in clusters and in patches. When the blisters rupture, there is formation of a crust resulting in a sore. Cold sores or Oral Herpes commonly heal within a couple of weeks or so. Cold Sores or Oral Herpes are contagious and are transmitted by close contact, like kissing. Oral Herpes are at their most contagious when they ooze fluid; however, the virus can also be spread to other people even when there is no blister formation.

The cause of the cold sores is HSV-1 or herpes simplex virus and this virus is closely related to HSV-2 which causes the genital herpes. These two herpes simplex viruses may affect the mouth or the genitals, and can spread through oral sex.
