What is genital herpes? Genital herpes is a common type of sexually transmitted disease marked by outbreaks of blisters and lesions in the genital area. Genital herpes is caused by infection of the herpes simplex virus type 1 (HSV-1) or type 2 (HSV-2). HSV-2 is the most common cause of genital herpes. About one out of six people 14 to 49 years of age has genital herpes caused by the HSV-2 infection, according to the Centers for Disease Control and Infection (Source: CDC). Genital herpes is not curable, but it is preventable and controllable in many cases. Genital herpes is diagnosed by testing a small sample of cells or drainage taken from the suspected herpes blister or lesion. A blood test can also check for the specific antibodies that are produced by the immune system in response to a genital herpes infection. Any person who engages in sexual activity can contract and pass on a genital herpes infection. This includes heterosexual, homosexual, and bisexual men and women. The more sexual partners a person has, the greater the risk of catching a genital herpes infection. Genital herpes can also be passed from an infected mother to her baby during vaginal delivery and result in serious complications. In some cases, genital herpes can lead to serious complications, such as meningitis and death of a newborn that was exposed to the disease during pregnancy or delivery. People who have impaired immune systems are also at risk for serious complications, such as the herpes virus spreading throughout the body. Using safer sex practices, seeking regular medical care, and seeking early, regular prenatal care can help reduce the risk of serious complications of genital herpes.
