Human papilloma virus (HPV)

HPV is the name of a group of viruses that affect your skin and other moist membranes of the body, including the cervix (neck of the womb), anus, mouth and throat. There are over 100 different types of HPV, and some of these are more likely to affect genital skin.

How do you get HPV?

HPV is very common and highly infectious. It is so common that almost all men and women catch it at some time or another. HPV affecting genital tissue is spread through genital-skin contact during sexual activity. HPV is not spread through blood or other bodily fluids.

How do I know if I have HPV?

Most people who have HPV have no symptoms at all. Sometimes, however, HPV cause changes in the genital skin and cervix. These conditions include genital warts and cervical cancer. 

Genital warts 

• Genital warts are hard, irregular growths on the genital skin caused by HPV.
• They are sexually transmitted.
• Only about 10% of people who catch the virus grow warts.
• About 80% of people clear the infection, but this can take 2-3 years.
• Genital warts can be treated by the destruction of the overgrowth of skin cells by freezing and chemicals.
• No treatment gets rid of the virus HPV, but more often than not it clears up by itself. 

Cervical cancer

  • Some types of HPV can disrupt the normal functioning of the cells of the cervix and can eventually trigger the onset of cancer.Two types of HPV — 16 and 18 — are known to cause up to 70% of cervical cancer.  These types of HPV have no symptoms so many women will not know they have the infection. Although these infections are very common, most women will not go on to develop cervical cancer.
  • Cervical cancer has no symptoms in the early stages. If symptoms do develop, the most common is unusual vaginal bleeding, which occur after sex or in-between periods or after the menopause. 

Cervical screening

A cervical screening test (previously known as a smear test) is a method of detecting abnormal cells on the cervix. This can prevent cervical cancer as these abnormal cells can be treated early.

The test usually takes 5-10 minutes and involves a speculum (an instrument) being inserted gently into the vagina to hold the vaginal walls open. The doctor/nurse can then use a small brush to take some cells from the surface of the cervix. The sample is then sent to the laboratory to see whether any calls are abnormal.

Although most cases of cervical cancer occur in women between the ages of 30 and 45, some women can develop it earlier. The NHS offers cervical screening from the age of 25. 

How do I get treated for HPV?

There is no cure or treatment for HPV. In the majority of cases, it will be cleared by your immune system. The effects of the virus — such as genital warts or changes to the cells of the cervix — can be treated. If these occur, you should discuss these treatment methods with your doctor.

What would happen if I didn’t get treated for HPV?

Most cases of HPV are cleared by the immune system over time. Unfortunately, in some people HPV causes genital warts, anal and cervical cancer. Our screening program helps to prevent these changes from occurring.

How can I protect myself from developing HPV?

  • Although condoms can protect you against other STIs, they do not always protect you from HPV as they do not cover all of the genital skin.
  • The HPV vaccine protects against four main types of HPV: HPV types 6 and 8 which can cause genital warts and HPV 16 and 18 which are associated with cervical and also anal cancers.
  • Both men and women can have the HPV vaccine. It involves 3 injections over 6 months
