Cold sores are very contagious, especially in the first 2 or 3 days after an outbreak. Canker sores are extremely common; it is estimated that, in the United States, 80%-90% of the population has been infected by the cold sore virus by the time they are 50 years old. These sores are highly contagious until they heal. Transmitted by kissing an infected person or sharing eating utensils, towels, or razors, these sores are usually confined to the mouth area (particularly on and around the lip).

Why do people get cold sores when they have flu or with too much exposure to sunlight? Cold sore viruses tend to replicate in an environment that is warm. If you get yourself too much exposed to heat, chances are, you will get to experience a cold sore.

Because it is a virus, it is highly contagious. It can be spread by kissing or any contact with sores. Sometimes it spreads to another person even when there is no visibility of sores, because the virus stays in the saliva. However, you cannot catch the virus from using towels or if you touch contaminated surfaces.

Herpes simplex type 1 virus targets the immune system when a person is mentally distressed. They last for weeks together which becomes vulnerable for the person to get rid of it. But if you realize it early it would be easy to get rid of it early.

Cold sore cures, to this group, must be able to remove the herpes virus from the body to be a true cure. Since this virus cannot be removed by any known method, they feel there are no cold sore cures. On the other hand, the folks that say there ARE cold sore cures are talking about preventing the cold sores from actually occurring.

Every pathogenic disease is identified based on the display of a specific set of symptoms. The cause may be there, but if there are not any symptoms, there is no disease. This is true with cold sores as well. The primary symptom of a cold sore is the blister on the lip or nostril.

Cold sores are not only painful but they are usually extremely irritating as well. They quite often spread from one area of the lips to another and this is because the fluid contained within the sore is contagious when it comes into contact with other parts of the skin, especially around the immediate mouth area.

To prevent a cold sore you should keep your immune system in as good a shape as possible. This means you should try to keep from getting colds, or fevers. Protect yourself in inclement weather, take vitamin c, and stay on top of your health. If you get cold sores because your immune system is weakened then you need to take vitamin supplements to keep your immune system in good shape.

Oral herpes is the most common manifestation of the herpes virus, by far, with genital herpes being second. Cold sores normally remain dormant in the sensory nerve cells around the site of initial infection (usually the face around the mouth), until an active outbreak occurs--an active outbreak is when you get a visible cold sore. This will usually last between 2 and 21 days, with an average for most people of about a week.
