On occasion we have seen some friend of ours with a blister on the lip area, it manifests that it is very painful and that the doctor has told you that it’s a cold sores. This blister that is commonly known in popular speech as fire has a cause, and on these occasions we have asked more than once what causes cold sores? Labial herpes is a viral disease that can be caused by two different viruses belonging to the family herpesviridae, one of them and the most frequent called Herpes Simplex Virus type 1 is the one that causes almost all infections herpes in the buccal and labial area, although there are other viruses that in smaller proportion also causes an infection of herpes Labialisis the Herpes Simplex Virus type 2; This type of virus is causing most of the times of genital herpes, but it can spread the area of the lips due to close contact with the infected area. Kisses, or contact with the affected area, may be what causes cold sores, since the virus is present in the wounds blistering and they can be transmitted either by direct or indirect contact with the area, it should be noted that when we speak of an indirect contact, we speak of come into contact with any object that has been directly contaminated with the affected area. Now that we know what causes cold sores, we can have more caution and we should also remember, that to be a viral infection wounds will heal themselves once the virus has ceased to affect the area, these blisters usually heal without leaving any wound in a period of 6 to 12 days, so it’s about time to make these lesions disappear alone and in this period the virus enters dormancy.
