Cold sores, also referred to as fever blisters, usually form on the lips and around the mouth. They are caused by the herpes simplex virus type I (HSV I), which lives inside nerve tissues. There is no known cure for this virus. It is contagious and can be spread by direct contact to the cold sore or contact with infected fluid. Statistics pulled from herpes-coldsores.com show that approximately 100 million Americans are infected with the HSV-1 virus.
Cold sores do not discriminate against age, race, gender or social status. And while some people can be infected with the virus without being symptomatic, it is still possible for them to spread it to others. To prevent spreading the virus, avoid contact with infected areas and fluids. This includes kissing, sharing glasses, utensils and razors.
Symptoms
Prior to the appearance of blisters, symptoms may include soreness around the mouth and tenderness of the lips. Some may also experience a fever and swollen glands. After the appearance of blisters, cold sores usually break open, leak clear fluid, scab over and then heal. This whole process can take anywhere from days up to a couple of weeks. But, with proper treatment, the pain and discomfort of an outbreak can be minimized.
