Genital herpes is a sexually transmitted infection (STI). It is caused by a virus called herpes simplex virus(HSV).
The herpes virus causes painful sores and blisters in the genital area, the anus, the thighs and the buttocks. Sometimes though, the HSV infection causes no symptoms at all; in fact many people are infected with HSV and don’t know it.
