Genital herpes is a sexually transmitted infection (STI) caused by the herpes simplex virus (HSV-2). Having unprotected sexual intercourse or contact with an infected person can cause the virus to spread even if the infected person displays no active symptoms. An outbreak of genital herpes can cause painful symptoms such as blisters, ulcers and sores to occur on and around the genitals, anus, thighs, or buttocks. However, most people who carry the infection will be unaware that they are infected and will not experience any symptoms until the virus is triggered, causing an outbreak of genital herpes. Although this STI cannot be cured, it can be controlled with effective anti-viral medications. Such as Aciclovir, Valtrex and Famvir.
