Genital warts
Genital warts
About genital warts and causes
Genital warts are one of the most common
sexually transmissible infections (STIs)
.
They are caused by the
human papillomavirus (HPV)
. There are more than 200 strains of HPV.
Only around 40 types of HPV can affect the genitals. Not all cause visible
warts
.
Genital warts can appear:
around the genitals and anus
sometimes inside the vagina, rectum or urethra.
Signs of genital warts
Genital warts appear as painless growths and may be:
flat or raised
single or multiple
clustered together with a cauliflower-like appearance.

Genital warts may not have any symptoms
In many cases, HPV is known as a ‘subclinical’ infection. This means you may be carrying HPV on your
skin
, even though you do not have any visible warts.
Subclinical HPV infection is common in people of all genders It is detected more often in people with a cervix during
cervical screening
.
How genital warts spread
HPV infection can occur after direct contact with a visible wart or contact with genital skin where the virus is present. This can occur even if there are no visible warts.
HPV can spread by direct skin-to-skin contact during:
vaginal sex
anal sex
oral sex
– it is rare to transmit HPV to the mouth through oral sex.
Warts may appear within a few weeks after sex with a person who has HPV.
Sometimes warts may take months to appear, or not at all. This can make it hard to know when you got the virus and who you got it from.
Genital warts treatment
For most people, the body’s immune system will get rid of the virus over time.
It is important to remember that treatment does not get rid of the virus. It only treats the visible warts.
Treatment aims to remove visible warts, usually for cosmetic reasons. Always consult your doctor about any treatments.
Over-the-counter wart treatments are not suitable for genital warts.
Treatment options for genital warts include:
Cryotherapy
– warts are frozen off with liquid nitrogen. Several treatments may be required.
Podophyllotoxin
– this lotion can be applied at home. It is most effective on multiple warts that are easy to get to. Be careful to protect the unaffected skin. (Podophyllotoxin cannot be used during pregnancy.)
Imiquimod cream
– applied once a day, 3 times a week for up to 3 months. (Not recommended for use in pregnancy.)
Laser or diathermy treatment
– used for larger numbers of warts or when other treatment options have not been effective. Laser or diathermy treatment is administered in hospital under general anaesthetic. (This procedure does not get rid of the virus, it helps to get rid of the visible warts.)
Genital warts recurrence
After treatment for warts:
The virus may persist on the skin, even though the visible wart has gone. This means that warts may reappear.
If a wart reappears, it does not necessarily mean that you have caught the infection again.
In most cases, the wart will eventually disappear for good. This is due to the body’s natural immune system clearing the virus from the body.
HPV and cervical cancer
Certain types of HPV can infect the cervix. These can cause cell changes that may, over many years, increase your risk of
cervical cancer
if the body doesn’t clear the virus naturally.
The types of HPV that cause visible genital warts do not progress to cervical cancer.
Cervical screening
To reduce your cervical cancer risk, screening is available through the
National Cervical Screening
Program
External Link
for:
anyone with a cervix aged 25 and 74 years every 5 years
The
Cervical Screening Test
looks for the presence of HPV. Cervical screening is recommended for those who have been sexually active, even if you have had the HPV vaccine.
To do this test, you can see a doctor or nurse who will give you a swab to self collect a sample from high in your vagina. Or, if you prefer, the doctor or nurse can collect the sample for you.
The cervical screening test is a tool used to detect HPV on the cervix that may lead to
cervical cancer
.
Most HPV found on the cervix will clear naturally without treatment. If you are at high-risk you may need closer monitoring and treatment to remove them. Seek advice from your doctor.
Some people who have had a
hysterectomy
may still require cervical screening tests. You should discuss this with your health provider.
Genital warts and HPV vaccines
There are 2 HPV vaccine brands available in Australia to help prevent cervical cancer:
Gardasil®9
Cervarix® (not registered for use by males in Australia and is only available on the private market).
These vaccines work by preventing infection with 2 types of HPV – types 16 and 18. These are the types that have been shown to cause 70% of cervical cancers.
Gardasil®9 provides protection against 9 types of HPV. In addition to types 16 and 18, it also protects against HPV types 6 and 11, which cause almost all genital warts, and types 31, 33, 45, 52 and 58, which cause an additional 15% of all cervical cancers.
Gardasil®9 replaces the Gardasil® vaccine (which protected against the four types of HPV – types 6, 11, 16 and 18).
HPV immunisation
HPV immunisation
consists of a single dose vaccine schedule for most people.
If you are immunocompromised, you may need 3 doses of the HPV vaccine for protection from the virus
In Victoria, the HPV Gardasil®9 vaccine is available free of charge under the
National Immunisation Program
(NIP)
External Link
for young people:
12 to 25 years – ideal age for vaccination is 12 to 13 years, before
sexual activity
(and therefore exposure to HPV) commences.
The vaccine is usually given to
young people in year 7 of secondary school
by their local council immunisation service.
It is also available through:
a local doctor (GP)
community pharmacy
council immunisation session.
A catch-up program
is available for young people up to 25 years who missed HPV Gardasil®9 vaccination at school.
The vaccine provides the best protection if it’s completed before a person becomes sexually active.
HPV vaccine and over 26 years
The HPV vaccine is not usually recommended for adults aged 26 and older, as they may have been already exposed to HPV.
If you are 26 years and over and you wish to be vaccinated for HPV, speak with your doctor.
Preventing the spread of genital warts
You can help reduce the risk of spreading genital warts by
practising safe sex
by using
internal
and
external condoms
.
Because condoms don’t cover all the genital skin that is exposed during sexual contact, you may still get HPV through skin-to-skin contact.
Transmission of genital warts can occur when a wart is present, but may also occur when there are none.
Genital warts and sexual relationships
If you have
regular sexual relationships
, especially if you and your partners have genital warts, the benefits of condom use is unclear. Discuss this issue with your doctor or with a nurse at a sexual health clinic.
