What Causes Cold Sores?

The most common way the virus is spread is through physical contact, such as kissing. Washing your hands thoroughly after touching the affected area will help prevent spreading the virus to other parts of your body or another person. A cold sore infection occurs when latent herpes simplex virus particles become reactivated. It is not a sign of a recently acquired herpes simplex infection. Also known as primary herpetic stomatitis, the initial herpes simplex virus infection usually does not take the form of a cold sore. It is for this reason that a person may not associate their initial exposure to the herpes virus with their current outbreak. With initial infection, the virus penetrates small breaks in the skin caused through injury or trauma, and then travels to the nerve roots on the spinal cord, where it lies dormant. Whenever our immune systems are low, the virus travels through the body down to the sensory nerves to the skin. When the virus reaches the cells of the skin, it multiplies and damages the skin cells, resulting in blisters. Eventually a cold sore develops. Whether a cold sore is visible or not, this virus is always seeking new cells to infect. This process is called viral shedding. Because there are large numbers of herpes particles being shed or released, it is extremely easy to expose or even infect others. The eyes seldom become infected, but it would be wise to protect them from the virus, since it can potentially cause eye problems and, in extreme cases, blindness. Managing your stress levels and avoiding excessive sunlight can help to reduce outbreaks.
