Genital herpes

Genital herpes is highly contagious and caused by a type of the herpes simplex virus (HSV). HSV enters your body through small breaks in your skin or mucous membranes. Most people with HSV never know they have it, because they have no signs or symptoms. The signs and symptoms of HSV can be so mild they go unnoticed. When signs and symptoms are noticeable, the first episode is generally the worst. Some people never experience a second episode. Other people, however, can experience recurrent episodes over a period of decades.

When present, genital herpes signs and symptoms may include:

• Small, red bumps, blisters (vesicles) or open sores (ulcers) in the genital, anal and nearby areas
• Pain or itching around the genital area, buttocks and inner thighs

The initial symptom of genital herpes usually is pain or itching, beginning within a few weeks after exposure to an infected sexual partner. After several days, small, red bumps may appear. They then rupture, becoming ulcers that ooze or bleed. Eventually, scabs form and the ulcers heal.

In women, sores can erupt in the vaginal area, external genitals, buttocks, anus or cervix. In men, sores can appear on the penis, scrotum, buttocks, anus or thighs, or inside the urethra, the tube from the bladder through the penis.

While you have ulcers, it may be painful to urinate. You may also experience pain and tenderness in your genital area until the infection clears. During an initial episode, you may have flu-like signs and symptoms, such as headache, muscle aches and fever, as well as swollen lymph nodes in your groin.

In some cases, the infection can be active and contagious even when sores aren't present.
