What is Herpes?
Genital herpes is a sexually transmitted disease caused by the herpes simplex virus (HSV). There are two types of herpes simplex viruses: Simplex I and Simplex II. Simplex I usually affects the mouth (cold sores). Simplex II usually affects the genitals. Both types can be transmitted sexually.
How is herpes spread?
Herpes viruses are spread by contact between the infected part of the body and an uninfected part of the body. This means that an active sore is on the mouth, it can then be transmitted to the genitals if oral sex is performed. It can be spread by vaginal, anal, or oral sex, and by general touching or kissing. Herpes can also be spread while no sores are visible.
