Herpes simplex virus type 1 (HSV-1) infections are most commonly acquired during childhood and cause oral ulcers and cold sores. However, HSV-1 infection is an increasing cause of genital herpes due to oral-genital contact. HSV-2 is transmitted through sexual contact and is an infrequent cause of oral herpes. Asymptomatic viral shedding is twice as common in women infected with genital HSV-2 as in those with genital HSV-1. A similar difference may exist in men.
