Crab (Pubic Lice) Prevention

Crabs are usually spread by direct skin-to-skin intimate contact. Avoid contact with known infected people and textiles or clothing that may have been contaminated by someone who is infected with pubic lice. To avoid spreading the lice, a person with crabs should not have close or intimate contact with anyone else until the infestation has been fully treated. After treatment has been completed, ensure that all clothing and linens have been disinfected to avoid re-infection or spread of the infection to someone else in the home.

Outlook for Crab (Pubic Lice) Infection

If untreated, itching and symptoms will continue. Eventually everyone within close contact with the infected individual will become infected and develop symptoms. If medication, combing, and hygiene are used properly, the infection should clear.

Be wary of re-infection. Continued contact will reintroduce the infection even after the home care measures are taken.
