The two major types of herpes are oral herpes and genital herpes, though other forms also exist. Oral herpes involves the face or mouth.
Herpes gladiatorum is one of the most infectious of herpes-caused diseases, and is transmissible by skin-to-skin contact. The disease was first described in the 1960s in the New England Journal of Medicine. It is caused by contagious infection with human herpes simplex virus type 1 (HSV-1), [1] which more commonly causes oral herpes (cold sores).
Symptoms, when they occur, may include watery blisters in the skin of any location of the body, or in mucous membranes of the mouth, lips, nose, genitals, [1] or eyes (herpes simplex keratitis).

[1] [9] The rash usually heals within ten days, but the virus remains dormant in the trigeminal ganglion. [1] The virus may periodically reactivate to create another outbreak of sores in the mouth or lip. [1] The cause is usually herpes simplex virus type 1 (HSV-1) and occasionally herpes simplex virus type 2 (HSV-2). [1]
