Recurrences may be more frequent for people with weakened immune systems. No one is sure. Other infections, stress, surgery, menstruation, sexual intercourse, and skin irritations like sunburn may bring on recurrences. A good diet, enough rest and sleep, and peace of mind may prevent recurrences. Herpes recurs in about half of the people who have it.
Recurrences are individual and vary.
Some people rarely have them. Others have them often. Clinicians diagnose herpes by testing fluids taken from the sores. Sores are often seen during pelvic exams. If you suspect you have herpes sores, see a clinician as soon as possible.
