What are genital warts?

Genital warts Click here to see an illustration. are skin growths in the groin, genital, or anal areas. They can be different sizes and shapes. Some look like flat white patches, and others are bumpy, like tiny bunches of cauliflower. Sometimes you can't see the warts at all.

Genital warts are spread by skin-to-skin contact. The virus is usually spread through sexual activity. Genital warts are a common sexually transmitted infection (STI). A sexually transmitted infection is also called a sexually transmitted disease (STD).

What causes genital warts?

Genital warts are caused by the human papillomavirus, or HPV. Some types of HPV cause genital warts. But these are not the same types of HPV that cause abnormal cervical cell changes and cervical cancer.

You are more likely to get genital warts if you:

  • Do not use condoms every time you have sex or genital contact.
  • Have more than one sex partner or have a high-risk partner(s) who has had multiple sex partners or HPV-infected sex partners.
  • Start sexual activity before age 18.
  • Have an impaired immune system that makes it hard for your body to fight infection.

What are the symptoms?

Most people infected with the virus that causes genital warts don't have symptoms. But if they do, the symptoms may be so mild that they may not know they are infected. The symptoms may include pain, itching, and bleeding.

If you have symptoms, they will probably occur 2 to 3 months after infection. But you can have symptoms from 3 weeks to many years after infection.

Visible genital warts appear only during active infection. But it is possible to spread the virus even if you can't see the warts.

How are genital warts diagnosed?

A doctor can often tell if you have genital warts by looking closely at your genital and anal areas. He or she may ask you questions about your symptoms and your risk factors. Risk factors are things that make you more likely to get a disease.

Sometimes the doctor takes a sample of tissue from the wart for testing.

How are they treated?

Talk to your doctor about whether you should treat genital warts. They usually go away with no treatment, but they may also spread. Most people decide to treat them because of the symptoms or how the warts look. But if you don't have symptoms and are not worried about how the warts look, you can wait and see if the warts go away.

If you do decide to treat genital warts, talk to your doctor about the best treatment for you. There are prescription medicines you or your doctor can put on the warts. Or your doctor can remove them with lasers, surgery, or by freezing them off.

Even if you treat visible warts or your warts go away without treatment, the HPV infection can stay in your body's cells. It is possible to spread genital warts to your partner even if you have no signs of them.

Finding out that you have genital warts may make you feel bad about yourself or about sex. Counselling or a support group may help you feel better.

Can genital warts be prevented?

The best way to keep from getting genital warts—or any other STI—is to not have sex. If you do have sex, practise safe sex.

  • Before you start a sexual relationship, talk with your partner about STIs. Find out whether he or she is at risk for them. Remember that a person can be infected without knowing it.
  • If you have symptoms of an STI, don't have sex.
  • Do not have sex with anyone who has symptoms or who may have been exposed to an STI.
  • Do not have more than one sex partner at a time. Having several sex partners increases your risk for disease.
  • Use condoms. Condoms may help reduce the risk of spreading genital warts, but they do not protect the entire genital area against skin-to-skin contact.

A new vaccine called Gardasil blocks four types of HPV: two that cause cervical cancer and two that cause genital warts. You get three shots over 6 months. Gardasil is recommended for females 9 to 13 years old. Females 14 to 26 years also benefit from getting the vaccine. You may have to pay for the vaccine yourself.
