[Recurrent labial herpes. How to treat and prevent it best]

Labial herpes is a recurrent muco-cutaneous disorder caused by the herpes simplex virus (HSV), particularly the HSV type I. It affects 10 to 30% of the adult population. The recurrence rate varies from episodic events to monthly recurrences. Several triggering factors have been identified. They include physical factors such as ultraviolet radiations and any local traumatism such as dental and neurosurgical interventions, and dermo-cosmetic procedures of the face. Hormonal factors are also involved including those related to menses and pregnancy. Psychogenic factors, particularly severe stress are also involved. Any other intercurrent infection may also be complicated by recurrent labial herpes. The management of recurrent labial herpes currently relies on the identification and possible avoidance of triggering factors, and on the use of antiviral agents. There is no curative treatment available so far.
