Crabs (Pubic Lice) Symptoms and Treatment

Pubic lice are parasitic insects which infest human pubic hair and suck the blood of the surrounding skin for nourishment. Infection is common and found worldwide, with almost all cases occurring as a result of close physical contact, including sexual activity.

Symptoms usually begin with extreme irritation, which leads to scratching that can cause secondary infection and eczema. If you experience these symptoms, your doctor or other health-care provider can tell if you have crabs by examining the infested area. They will then usually prescribe medicated creams or shampoos to treat the infection, or recommend some that do not require a prescription.

In addition, you can take the following steps:

• Bathe thoroughly and towel dry. Then apply the medicated liquid to cool, dry skin between the area from chest to knees.
• Leave it on for 20 minutes only and then bathe and dry.
• Comb your pubic hair with a fine tooth comb to remove any eggs.
• Wash or dry clean all clothing, towels and bedding used in the last two days. Articles that cannot be washed can be sealed in a plastic bag for 72 hours.
• Repeat the treatment in 7 to 10 days.
• Sexual partners should also be treated.

You can reduce your risk of contracting crabs by having sexual intercourse only with a partner you are sure is not infected. Always use a latex or polyurethane condom and be aware that the greater the number of sexual partners you have, the greater your risk.

Note that there is nothing to stop a person becoming re-infested after treatment if they are exposed to crabs again.
