Herpes is a common infection caused by the herpes simplex virus (HSV). Herpes usually causes painful blisters that break open and form sores. The most common sites of outbreaks are the genitals, mouth and rectal area. There are approximately 40 million Americans currently infected with genital herpes, though most are asymptomatic (show no symptoms). An estimated 200,000 new cases of genital herpes are diagnosed each year in the U.S. What are the different types of Herpes Simplex?

A person can become infected with the virus by contact with infected skin on the genitals, mouth, rectal area, or buttocks. The infection is often passed from person to person during sexual intercourse.

It is not known how often asymptomatic shedding occurs. Once a person is infected, the virus stays in the body for life. There is no cure for herpes, although symptoms can be treated.
