Gential herpes is a sexually transmitted infection caused by an infection with the herpes simplex virus (HSV). There are two types of the herpes simplex virus- herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2). Either type can cause genital herpes, but HSV-2 is responsible for most cases. Affected individuals suffer from recurrent bouts of itchy and/or painful blisters typically on or around the genitals or anus. Blisters can also develop on other parts of the body such as the buttocks, hips, and thighs. The blisters typically pop, develop into open sores, and then crust and heal over. While infection with the herpes virus is life-long, there are oral antiviral medications which can be taken to speed the healing and control or prevent outbreaks.
