What are genital warts? (top)
Genital warts
are the most easily recognized sign of genital HPV (Human
Papillomavirus) infection. Many people, however, have a genital HPV
infection without genital warts.

Genital warts
are soft, moist, or flesh colored and appear in the genital area within
weeks or months after infection. They sometimes appear in clusters that
resemble cauliflower-like bumps, and are either raised or flat, small or
large. Genital warts can show up in women on the vulva and cervix, and
inside and surrounding the vagina
How are genital warts spread?
(top)
Genital warts
are very contagious and are spread during oral, vaginal, or anal sex
with an infected partner. They are transmitted by skin-to-skin contact
during vaginal, anal, or (rarely) oral sex with someone who is infected.
About two-thirds of people who have sexual contact with a partner with
genital warts will develop warts, usually within 3 months of contact.
In women, the
warts occur on the outside and inside of the vagina, on the opening to
the uterus (cervix), or around the anus.
In men, genital
warts are less common. If present, they usually are seen on the tip of
the penis. They also may be found on the shaft of the penis, on the
scrotum, or around the anus.
Rarely, genital
warts also can develop in your mouth or throat if you have oral sex with
an infected person.
Like many STIs (sexually
transmitted infections), genital HPV infections often do not have
signs and symptoms that can be seen or felt. One study sponsored by the
National Institute of Allergy and Infectious Diseases (NIAID) reported
that almost half of women infected with HPV had no obvious symptoms. If
you are infected but have no symptoms, you can still spread HPV to your
sexual partner and/or develop complications from the virus.
What are the
signs and symptoms of genial warts? (top)
Most people who
have a genital HPV infection do not know they are infected. The virus
lives in the skin or mucous membranes and usually causes no symptoms.
Some people get visible genital warts, or have pre-cancerous changes in
the cervix, vulva, anus, or penis. Very rarely, HPV infection results in
anal or genital cancers.
Genital warts
usually appear as soft, moist, pink, or flesh-colored swellings, usually
in the genital area. They can be raised or flat, single or multiple,
small or large, and sometimes cauliflower shaped. They can appear on the
vulva, in or around the vagina or anus, on the cervix, and on the penis,
scrotum, groin, or thigh. After sexual contact with an infected person,
warts may appear within weeks or months, or not at all.
How are genital warts
diagnosed? (top)
Your health care
provider usually diagnoses genital warts by seeing them. If you are a
woman with genital warts, you also should be examined for possible HPV
infection of the cervix.
Your provider
may be able to identify some otherwise invisible warts in your genital
tissue by applying vinegar (acetic acid) to areas of your body that
might be infected. This solution causes infected areas to whiten, which
makes them more visible. In some cases, a health care provider will take
a small piece of tissue from the cervix and examine it under the
microscope.
If you have an
abnormal Pap smear result, it may indicate the possible presence of
cervical HPV infection. A laboratory worker will examine cells scraped
from your cervix under a microscope to see if they are cancerous.
How are genital warts
and HPV treated? (top)
HPV has no known
cure. There are treatments for genital warts, though they often
disappear even without treatment. There is no way to predict whether the
warts will grow or disappear. Therefore, if you suspect you have genital
warts, you should be examined and treated, if necessary.
Depending on
factors such as the size and location of your genital warts, your health
care provider will offer you one of several ways to treat them.
• Imiquimod cream
• 20 percent podophyllin antimitotic solution
• 0.5 percent podofilox solution
• 5 percent 5-fluorouracil cream
• Trichloroacetic acid (TCA)
If you are
pregnant, you should not use podophyllin or podofilox because they are
absorbed by your skin and may cause birth defects in your baby. In
addition, you should not use 5-fluorouracil cream if you are expecting.
If you have
small warts, your health care provider can remove them by one of three
methods.
• freezing
(cryosurgery)
• burning (electrocautery)
• laser treatment
If you have large warts that have not responded to other treatment, you
may have to have surgery to remove them.
Some health care
providers use the antiviral drug alpha interferon, which they inject
directly into the warts, to treat warts that have returned after removal
by traditional means. The drug is expensive, however, and does not
reduce the rate that the genital warts return.
Although
treatments can get rid of the warts, none get rid of the virus. Because
the virus is still present in your body, warts often come back after
treatment.
What are
some of the complications from genital warts? (top)
Cancer
Some types of
HPV can cause cervical cancer. Other types are associated with vulvar
cancer, anal cancer, and cancer of the penis (a rare cancer).
Most HPV
infections do not progress to cervical cancer. If you are a woman with
abnormal cervical cells, a Pap test will detect them. If you have
abnormal cervical cells, it is particularly important for you to have
regular pelvic exams and Pap tests so you can be treated early, if
necessary.
Pregnancy and
Childbirth
Genital warts
may cause a number of problems during pregnancy. Sometimes they get
larger during pregnancy, making it difficult to urinate. If the warts
are in the vagina, they can make the vagina less elastic and cause
obstruction during delivery.
Rarely, infants
born to women with genital warts develop warts in their throats
(laryngeal papillomatosis). Although uncommon, it is a potentially
life-threatening condition for the child, requiring frequent laser
surgery to prevent obstruction of the breathing passages. Research on
the use of interferon therapy with laser surgery indicates that this
drug may show promise in slowing the course of the disease.
How can genital warts be
prevented? (top)
The only way you
can prevent getting an HPV infection is to avoid direct contact with the
virus, which is transmitted by skin-to-skin contact. If you or your
sexual partner has warts that are visible in the genital area, you
should avoid any sexual contact until the warts are treated.
Research studies
have not confirmed that male latex condoms prevent transmission of HPV,
but studies do suggest that using condoms may reduce your risk of
developing diseases linked to HPV, such as genital warts and cervical
cancer. Unfortunately, many people who don’t have symptoms don’t know
that they can spread the virus to an uninfected partner.
