Cold Sore Virus
The Cold Sore Virus Namely Herpes Simplex Virus
Cold sores are a common contagious disease caused when the cold sore virus, herpes simplex virus or HSV present dormant inside the body suddenly becomes active. The person having this disorder gets fluid-filled blisters either on the mucous membranes or on the red puffy areas of the skin. These might cause pain and skin irritation but are otherwise harmful. They get healed within two weeks time.
Cold sore virus is of two types namely HSV-1 and HSV-2. HSV-1 is more common and causes oral herpes or cold sores. HSV-2 causes genital herpes. It is important to note that almost 80% of human beings carry natural antibodies in their body against HSV-1. At the same time, only around 25% of the adult population bears antibodies against HSV-2.
Cold sores are highly contagious. The cold sore virus gets transmitted from one person to the other when they come in close personal contact with each other. Usually, it is between three to five years of age that most people get into contact with the Herpes Simplex Virus. However, symptoms will appear only after reaching puberty. When the HSV attacks the cells of the skin’s outer layer or the epidermis, fluid-filled blisters are formed.
