Cold sores are caused by a form of the Herpes Simplex Virus (HSV), and they're contagious. Once you have had an episode of cold sores, the virus lies dormant in the nerve cells of the skin and cold sores may reappear near the original site. You may experience an itch or heightened sensitivity before each attack. Outbreaks frequently occur following sun exposure, trauma, examination stress, emotional stress, or menstruation. Almost everyone has been exposed to HSV ¯_ about 80% of the population ¯_ and about a third of us experience recurrent symptoms.
Signs and symptoms of cold sores include:
Tingling, burning or itching sensation prior to the cold sore developing.
Small fluid-filled blisters appear on or around the lips.
If untreated, a cold sore will generally last between 10 and 14 days. Blistex Antiviral Cold Sore Cream, containing aciclovir 5%, can be used to treat an infection.
Remember: Cold sores are contagious. Touching the infected area may result in the infection being spread elsewhere. The virus is easily spread to other people.
* For effective treatment of Cold Sores.
* Treat at the first sign of a tingle.
Commence treatment at the first symptoms of a cold sore. This may be a tingling, burning or itching sensation.
Apply 5 times a day for 5 to 7 days to the affected area.
