What is human papillomavirus infection?
papillomavirus (HPV) is a viral infection that is passed between people through
skin-to-skin contact. There are more than 100 varieties of HPV, but most
emphasis is given to the 40 varieties that affect the genitals, mouth, or
throat, that are passed through sexual contact.

problems. These include genital warts and warts in the throat (known as
recurrent respiratory papillomatosis, or RRP). HPV can also cause cervical
cancer and other cancers of the genitals, head, neck, and throat.
The types of

growth. Regular screenings can help diagnose HPV-related health problems
earlier. This can improve outlook and increase chances of survival.
Testing for human papillomavirus infection
The Food and
Drug Administration (FDA) approved the first DNA test for HPV in 2014. Updated guidelines recommend that women have their
first Pap test (Pap smear) at age 21 and then start getting the HPV test at the
same time they get a Pap test, beginning at age 30. Regular Pap tests help to
identify abnormal cells in women. These can signal cervical cancer or other
HPV-related problems. Women ages 30 to 65 should then be screened every five
years with Pap and HPV co-testing. If you are under the age of 30, your doctor
or gynecologist may also request an HPV test if your Pap smear results are

changes that lead to cancer often take 10 or more years to develop and HPV
infections often go away on their own in one or two years without causing
cancer. You may want to follow a course of watchful waiting instead of
undergoing treatment for the abnormal or precancerous cells resulting from an
infection. Your doctor may also want to do follow-up testing with colposcopy.
This procedure uses an instrument (colposcope) to examine the vagina and the
cervix more closely and look for abnormal areas.

Preventing human papillomavirus infection
has had sexual intercourse is at risk for HPV infection. It’s impossible to
know who will develop health problems from HPV, but people with weakened immune
systems may be more at risk.
The easiest ways to prevent HPV are to use condoms and to limit sexual
partners. In addition, the CDC
recommends the HPV vaccine for boys and girls aged 11 or 12. Women and men can
get vaccinated until age 26. The vaccine is said to protect against the types
of HPV associated with cancer and also to prevent some types that cause warts.
To prevent health
problems associated with HPV, be sure to get regular health checkups,
screenings, and Pap smears.
