What is genital herpes?
Genital herpes is a sexually transmitted disease (STD) caused by the herpes simplex viruses type 1 (HSV-1) or type 2 (HSV-2).
How common is genital herpes?
CDC estimates that, annually, 776,000 people in the United States get new herpes infections. Genital herpes infection is common in the United States. Nationwide, 16%, or about one out of six, people aged 14 to 49 years have genital HSV-2 infection. Over the past decade, the percentage of persons with genital herpes infection in the United States has remained stable.
Transmission from an infected male to his female partner is more likely than from an infected female to her male partner. Because of this, genital HSV-2 infection is more common in women (approximately one out of five women aged 14 to 49 years) than in men (about one out of nine men aged 14 to 49 years).
What are the symptoms of genital herpes?
Most individuals infected with HSV-1 or HSV-2 experience either no symptoms or have very mild symptoms that go unnoticed or are mistaken for another skin condition. Because of this, most people infected with HSV-2 are not aware of their infection. When symptoms do occur, they typically appear as one or more blisters on or around the genitals, rectum or mouth. The blisters break and leave painful sores that may take two to four weeks to heal. Experiencing these symptoms is sometimes referred to as having an “outbreak.” The first time someone has an outbreak they may also experience flu-like symptoms such as fever, body aches and swollen glands.
Repeat outbreaks of genital herpes are common, in particular during the first year of infection. Symptoms of repeat outbreaks are typically shorter in duration and less severe than the first outbreak of genital herpes. Although the infection can stay in the body indefinitely, the number of outbreaks tends to decrease over a period of years.
