Doctor's Notes on Crabs (Pubic Lice)
Pubic lice are parasitic insects found on the genital area hair (pubic hair) of humans. The lice infestation is typically spread by sexual contact, but any skin contact can spread the condition. The lice may occasionally also be found on other areas of body hair. Public lice infestation occurs worldwide. Pubic lice have six legs including two front legs that are very large and look like the pincher claws of a crab. This is the origin of the nickname "crabs."
Signs and symptoms associated with public lice infestation include intense itching in the genital area. Small lice eggs, known as nits, may be seen attached to the hair shaft. Crawling lice may also occasionally be seen.
