Herpes

Genital herpes results from an infection by herpes simplex virus. There are several different kinds of human herpes viruses. Only two of these, herpes simplex type 1 (HSV-1) and type 2 (HSV-2), can cause herpes. HSV-2 is most often responsible for genital infections. HSV-1 usually causes oral herpes, but it can also cause genital herpes about 10-30% of the time. While the herpes virus can infect anyone, not everyone will show symptoms. Risk factors include early age at first sexual activity, multiple sexual partners, and a medical history of other sexually transmitted diseases (STDs).

The first symptoms of a primary herpes infection usually occur within two to seven days after contact with an infected person but may take up to two weeks. Symptoms of a primary infection are usually more severe than those of recurrent infections. For up to 70% of people, a primary infection causes general symptoms such as tiredness, headache, fever, chills, muscle aches, loss of appetite, and painful, swollen lymph nodes. These symptoms are greatest during the first three to four days of the infection and disappear within a week.

Most people with genital herpes experience prodromes, or symptoms of the oncoming disease. This might entail pain, burning, itching, or tingling at the site on the genital area, legs, or buttocks where blisters will form. The prodrome stage may occur anywhere from a few hours, to one or two days before an outbreak of the infection. Following that, small red bumps appear. These bumps quickly become fluid-filled blisters that may also fill with pus, and become covered with a scab. The blisters may burst and become painful sores. Blisters may continue to erupt for a week or longer. Pain usually subsides within two weeks, and the blisters and sores heal without scarring by three to four weeks. It is possible to pass the virus to other parts of the body by touching an open sore and then bringing the fingers into contact with the mouth, the eyes, or a break in the skin. The highest risk for spreading the herpes virus is the time during the appearance of blisters up to the formation of scabs. However, an infected person can spread herpes virus to other people even in the absence of sores.

Women can experience a very severe and painful primary herpes infection. In addition to the vaginal area, blisters often appear on the clitoris, at the urinary opening, in the rectum and around the anus, and on the buttocks and thighs. The cervix is almost always involved, causing a watery discharge. About one in 10 women get a vaginal yeast infection as a complication of herpes. In men, the herpes blisters usually form on the penis but can also appear on the scrotum, thighs, around the anus, and in the rectum. Men may also have a urinary discharge with a genital herpes infection. Both men and women may experience painful or difficult urination, swelling of the urethra, meningitis, and throat infections, with women experiencing these symptoms more often than men.

It is unknown exactly what triggers a latent herpes virus to activate, but several conditions seem to be connected with the onset of an active infection. These include illness, stress, tiredness, sunlight, menstruation, skin damage, food allergies, and extreme hot or cold temperatures. Most people with genital herpes experience one or more outbreaks per year. About 40% experience six or more outbreaks per year. Active recurrences of herpes are usually less severe than the primary infection. There are fewer blisters, less pain, and the time period from the beginning of symptoms to healing is shorter than the primary infection.

Genital herpes is a sexually transmitted disease caused by the herpes simplex virus. The disease is characterized by the formation of fluid-filled, painful blisters in the genital area.

Genital herpes is a sexually transmitted disease spread by vaginal, anal, and oral contact. The first herpes infection a person has is called a primary infection. It develops about four to seven days after contact with the disease. Once a person has been infected with the herpes virus, it cannot be completely cured. Instead, the virus can lay latent in the sensory nerve ganglia for days, months, or even years between outbreaks. When the virus becomes activated there is a recurrent infection of the skin. An active herpes infection is then obvious because of the sores that develop. However, an active infection may occur without visible sores. Up to 75% of people with herpes may not know they have the infection.

Newborn babies who are infected with herpes virus experience a very severe, and possibly fatal, disease called neonatal herpes. In the United States, one in 3,000-5,000 babies born will be infected with herpes virus. Babies usually become infected during passage through the birth canal, but they also can become infected during pregnancy if the membranes rupture early.
