Genital herpes

Alternate Names : Herpes - genital, Herpes simplex - genital, Herpesvirus 2, HSV-2

Symptoms & Signs

Many people with HSV-2 infection never have sores, or they have very mild symptoms that they do not even notice or mistake for insect bites or another skin condition.

If signs and symptoms do occur during the first outbreak, they can be quite severe. This first outbreak usually happens within 2 weeks of being infected.

Generalized or whole-body (systemic) symptoms may include:

  • Decreased appetite
  • Fever
  • General sick feeling (Malaise)
  • Muscle aches in the lower back, buttocks, thighs, or knees

Genital symptoms include the appearance of small, painful blisters filled with clear or straw-colored fluid. They are usually found:

  • In women: on the outer vaginal lips (labia), vagina, cervix, around the anus, and on the thighs or buttocks
  • In men: on the penis, scrotum, around the anus, on the thighs or buttocks
  • In both sexes: on the tongue, mouth, eyes, gums, lips, fingers, and other parts of the body
  • Before the blisters appear, the person may feel the skin tingling, burning, itching, or have pain at the site where the blisters will appear
  • When the blisters break, they leave shallow ulcers that are very painful. These ulcers eventually crust over and slowly heal over 7 - 14 days or more

Other symptoms that may occur include:

  • Enlarged and tender lymph nodes in the groin during an outbreak
  • Painful urination
  • Women may have vaginal discharge or, occasionally, be unable to empty the bladder and require a urinary catheter

A second outbreak can appear weeks or months after the first. It is almost always less severe and shorter than the first outbreak. Over time, the number of outbreaks tends to decrease.

Once a person is infected, however, the virus hides within nerve cells and remains in the body. The virus can remain "asleep" (dormant) for a long period of time (this is called latency).

The infection can flare-up or reactivate at any time. Events that can trigger latent infection to become active and bring on an outbreak include:

  • Fatigue
  • Genital irritation
  • Menstruation
  • Physical or emotional stress
  • Trauma

Attacks can recur as seldom as once per year, or so often that the symptoms seem continuous. Recurrent infections in men are generally milder and shorter than those in women.

Diagnosis & Tests

Tests can be done on skin sores or blisters to diagnose herpes. These tests are most often done when someone has a first outbreak and when a pregnant women develops genital herpes symptoms.

  • Culture of fluid from a blister or open sore may be positive for herpes simplex virus. The herpes simplex virus can in the culture in 2-3 days. It is most useful during the first outbreak.
  • A test called PCR performed on fluid from a blister shows small amounts of DNA. It is the most accurate test to tell whether the herpes virus is present in the blister.
  • Blood tests check for antibody levels to the herpes virus. These blood tests can identify whether someone has ever been infected with the herpes virus, even between outbreaks. It may be positive even if they've never had an outbreak.
