Pubic Lice (Crabs)What Are They?Pubic lice are tiny insects that can crawl from the pubic hair of one
person to the pubic hair of another person during sexual contact.
People can also catch pubic lice from infested clothing, towels, and
bedding. Once they are on a person's body, the insects live by sucking
blood from their host. Pubic lice are sometimes called "crabs" because
when seen under a microscope they look like tiny crabs.
What Are the Symptoms?Pubic lice can cause intense itching. A person who has been exposed
to pubic lice may notice tiny tan to grayish-white insects crawling in
their pubic hair. He or she may also see tiny oval-shaped, yellow to
white blobs called nits clinging to the hair. Nits are about the size of
a pinhead, and are the louse eggs. Nits can't be easily removed from
the hair with the fingers — "nit combs" made especially to remove the
eggs are sold at drugstores and many grocery stores.
Someone who has been exposed to pubic lice may not notice symptoms
for a few weeks. The primary symptom of pubic lice is itching,
especially at night, but lice can also leave bluish-grayish marks on the
thighs and pubic area from bites.
What Can Happen?It's unusual for pubic lice to create any serious health problems,
but the itching can be very uncomfortable, and it's easy to transmit
pubic lice to others. The female louse survives an average of 25 to 30
days and each can lay 20 to 30 eggs. Lice can also live away from the
body for 1 to 2 days. So it's important to get properly diagnosed and
treated, or it can take a while to get rid of them.
How Is It Treated?If you think you may have pubic lice or if you have had a partner who
may have pubic lice, see a doctor or gynecologist right away. If the
doctor diagnoses pubic lice, you may be prescribed medication or told to
buy an over-the-counter medicine that kills the lice and their eggs.
The important thing to remember is that the treatment you use may need
to be repeated after 7 to 10 days to kill any lice you didn't get the
first time. And anyone who is treated for pubic lice should be tested
for other STDs as well.
You will also need to dry clean or use very hot water and a hot dryer
cycle to wash and dry all your bedding, towels, or recently worn
clothing to properly kill the lice and their eggs. Anyone with whom
you've had sexual contact in the last month should also check for pubic
lice immediately. Although condoms help protect against other STDs, a
partner could still get pubic lice because the condom does not cover the
entire pubic area.
