Cold sores, or fever blisters, are caused by herpes simplex virus 1, which is related to but different from the
virus that causes genital herpes. Cold sores first appear three to ten days after exposure to the virus and may
last up to three weeks. The virus then remains permanently in the body, and moves into the nervous system
close to the lips. It will lie dormant there until triggered by fever, a cold or other viral infection, exposure to
sun and wind, stress, menstruation, high levels of amino acid Arginine, or depression of the immune system.
Studies have shown that between 30 and 60 percent of children carry the virus by the age of ten.
