Pubic Lice (or Crabs)
Cause:
A pubic lice infestation is caused by the crab louse Phthirus pubis.
Symptoms:
Itchiness in the pubic hair or occasionally in other hairy body parts. A close look may show tiny, crab-like lice.
How is it spread?:
Pubic lice is usually passed from person to person where pubic hair (or other hair) touches.
Treatment:
If you develop itching in the pubic area, you should see your doctor or clinic nurse. Effective lotions are available from pharmacies and you will not need a prescription.
It is important to tell sexual partners so they can get treatment too.
Prevention:
Condoms offer no protection against pubic lice.
