Herpes simplex infections (nongenital cold sores) facts
- Herpes simplex virus (HSV) can cause infections that affect the mouth, face, genitals, skin, buttocks, and the anal area.
- Of the two herpes simplex viruses (HSV 1 and HSV 2) that are associated with skin lesions, cold sores are most commonly caused by HSV-I.
- HSV infection may not produce symptoms, but when it does, the hallmark symptom is a group of blisters on a red base. These blisters dry up rapidly and leave scabs that last anywhere from a few days to a few weeks.
- The virus resides deep in the nerve roots and may reactivate at a later time, causing the same symptoms in the same location.
- Cold sores can be treated with antiviral medications to reduce pain and shorten healing time.
What are herpes simplex infections?
Herpes simplex virus (HSV) can cause infections that affect the mouth, face, genitals, skin, buttocks, and the anal area. This article will concentrate on nongenital herpes. Many people acquire the virus and have no symptoms. For others, painful blisters appear near the area where the virus entered the body. Typically, the blisters heal completely but reappear at some point in the future when least expected (or desired). In between attacks, the virus resides deep in the roots of the nerves that supply the involved area. When herpes simplex lesions appear in their most common location, around the mouth and lips, people often refer to them as "cold sores" or "fever blisters."
What causes cold sores?
There are two types of HSV, type 1 and type 2. In general, HSV-1, also known as herpes labialis, causes infections above the waist, most commonly as oral "cold sores." HSV-2 infections occur mainly below the waist, leading to genital herpes. However, both types of HSV are capable of infecting the skin at any location on the body.
Herpes infections, no matter where they occur first, have a tendency to recur in more or less the same place. Such recurrences may happen often (for example, several times per year) or only occasionally (for example, once or twice a year).
