Transmission and prevention: HSV is contagious and may be transmitted by any contact with the blisters until the sore is healed. These techniques are ineffective and may actually make the sores worse. Note: It is not recommended to use steroid ointments, dye-light therapy, smallpox vaccination or vitamin therapy (unless a deficiency exists). A drying agent (e.g., 70% rubbing alcohol or Blistex ointment) particularly when sores first appear.Zinc oxide ointment used after crusts have formed.A moistened styptic pencil used several times a day.With topical ointments, there is no demonstrated proof of effectiveness with recurrences. Acyclovir (Zovirax) or valacyclovir (Valtrex), taken orally, may decrease symptoms if started within 24-48 hours after the onset of symptoms.Denavir (pencyclovir cream), a topical antiviral cream recently cleared for marketing by the FDA that may decrease the duration of lesion pain and accelerate healing.However, some medications may relieve pain and soften HSV crusts on the skin. Treatment: There is no cure for cold sores. For instance, if exposure to sunlight usually precedes cold sores by 24-48 hours, one can be fairly confident that sunlight is a "trigger" and one should minimize exposure. Identifying triggers may allow a person to prevent recurrences by effectively removing these factors. In many cases, the precipitating factor is unknown. Both strains have similar signs, symptoms and course of disease, and both are contagious so contact should be avoided.Ī number of factors can trigger the HSV virus, including sunlight, sunburn, stress, fatigue, other infections, fever, menstruation and intestinal upset. For example, HSV-1 infection can be transmitted from mouth to genitals during oral sexual contact. However, it is possible to have a HSV-1 infection below the waist and vice versa. HSV-2 generally occurs below the waist (e.g., sexually transmitted sores on the genital area). HSV-1 generally occurs above the waist (e.g., a cold sore on the lip). Two types of HSV: have traditionally been differentiated by location. It has been estimated that nearly 50% of children entering kindergarten and 90% of adults have been infected with HSV, although a much smaller percentage has experienced symptoms. Some infected individuals never develop cold sores because the HSV is never reactivated however, others may experience recurring sores several times a year.Ĭauses: Herpes simplex virus (HSV) typically causes cold sores. Most people with recurrent cold sores cannot recall having had the first infection they may have been too young to remember or the infection may have been very mild. Once reactivated, HSV travels down the nerve cells into the skin, causing its characteristic fever blisters typically in the same location. Symptoms subside after the initial illness runs its course, but the virus remains in the nerve cells until reactivated. Painful sores in or around the mouth may make eating difficult. After the blisters have broken to reveal a bright red area, they dry up, crust and heal within 7-10 days. These small fluid-filled blisters then become cloudy and pus-filled. Recurrences are less severe and the individual may notice a burning or tingling sensation 24-48 hours before a cluster of blisters appear. Symptoms of the initial infection are similar to those of other viral infections and may include fever, swollen glands, fatigue and multiple sores in the mouth and on the gums. Cold sores typically result from a viral infection called herpes simplex virus (HSV).Ĭold sore blisters can occur on many different parts of the body but are most common on or around the lips, cheeks, or nose and also (on rare occasions) in the eye.
