If you suffer from cold sores often, here are some helpful facts about cold sores and some easy ways to treat them.
What Causes Cold Sores ?
The herpes simplex virus, or herpes virus 1, is the primary cause of cold sores. Herpes virus 1 is easily contracted and is present in about 90 percent of adults. Though many people suffer from frequent cold sores, some with the virus do not have outbreaks. Once infected with herpes virus 1, the virus remains in the body for life. Herpes may be dormant in the body for a while and then suddenly become active and cause outbreaks of cold sores.
The herpes virus 1 is very contagious and can be acquired through infected items such as eating utensils, a toothbrush, razors, dishes, towels, etc. It can also be sexually transmitted, even through kissing. Cold sore outbreaks can be triggered by a number of factors: emotional stress, illness, fever, pregnancy, chapped lips, menstruation, excessive sunlight exposure, immune system deficiencies, or other causes.
