Genital herpes is caused by two types of herpes simplex virus, HSV-1 and HSV-2. After a person is first infected, the herpes virus travels to nerve cells near the spine and stays there. When there is a trigger, the virus can become active again and cause a new outbreak of sores and blisters. Some common triggers for genital herpes outbreaks include:

• Illness
• Stress
• Sunlight
• Fatigue
• Menstrual periods
• Sexual intercourse
• Surgery
• Weak immune system

Its important to note that triggers may not be the same for everyone, and doctors are not certain how much lifestyle affects herpes symptoms. If you think one trigger is causing your symptoms, its best to consult with your doctor to determine what you should do about it. Treatment can shorten how long you have an outbreak and reduce symptoms.
