Cold sores are small, painful, fluid-filled blisters or sores that appear on the lips, mouth, or nose that are caused by a virus. The cold is the most commonly occurring illness in the entire world, with more than 1 billion colds per year reported in the United States alone.
Incubation period: For HSV-1, the amount of time between contact with the virus and the appearance of symptoms, the incubation period, is two to 12 days. Read What Your Physician is Reading on Medscape Herpes Simplex »Herpes simplex viruses (HSVs) are DNA viruses that cause acute skin infections and present as grouped vesicles on an erythematous base. HSV-1 often causes sores (lesions) inside the mouth, such as cold sores (fever blisters), or infection of the eye (especially the conjunctiva and cornea). Unlike most viral infections, the cold sore virus is not completely eliminated by the body defenses.


The virus is spread from person to person by kissing or other close contact with sores or even from contact with apparently normal skin that is shedding the virus. The likelihood of childhood infection is higher among those with lower socioeconomic status. Herpes simplex virus 2 (HSV-2) is usually, but not always, sexually transmitted. Once the blisters have dried and crusted over (within a few days), the risk of contagion is significantly lessened. However, a person infected with HSV can pass it on to another person even when a cold sore is not present. Despite popular myth, it is almost impossible to catch herpes (cold sores) from contaminated surfaces, towels, or washcloths.After the first infection, the virus enters the nerve cells and travels up the nerve until it comes to a place called a ganglion, which is a collection of nerve cells. Such recurrences may happen often (for example, once a month) or only occasionally (for example, once or twice a year).


Sometimes, young children also can get the disease. HSV can infect a fetus and cause abnormalities.
A mother who is infected with HSV may transmit the virus to her newborn during vaginal delivery, especially if the mother has an active infection at the time of delivery.
However, 60 - 80% of HSV infections acquired by newborns occur in women who do NOT have symptoms of HSV infection or a history of genital HSV infection. It's possible for the virus to be transmitted even when there are no symptoms or visible sores. The infection may be more severe and last longer in people who have a condition that weakens the immune system. Once an infection occurs, the virus spreads to nerve cells and stays in the body for the rest of a person's life.
