Answer by  DrMom (854)

Cold sores are caused by the herpes simplex virus. Like genital herpes they are with you for life. They are often triggered by stress or a compromised immune response. Some people go years between outbreaks and then suddenly will have a stressful period in their life and be plagued by them over and over again. To avoid them, avoid stress.
