What causes Herpes?
Herpes simplex is an incredibly common viral infection, usually in the form of cold sores or fever blisters. Most cases of herpes simplex are caused by virus type 1 (HSV-1), which causes small blisters, usually around the mouth. Virus type 2 (HSV-2) is usually the cause of genital herpes. Both forms of the herpes simplex virus are transmitted from person to person, either through skin to skin contact or through infected bodily secretions. The virus infects the site of infection, though it can travel along the nerve fibers and remain dormant within the skin until activated.
