ranges from 20% to 46% in young women worldwide2.

genital, cervical, vaginal, urethral and anal warts as well as conjunctival,
nasal, oral and laryngeal warts. HPV can lead to cancers of the cervix, vulva, vagina, and anus in women. In men, it can
lead to cancers of the anus and penis2.
Control: Correct usage of latex condoms greatly reduces,
but does not eliminate, the risk of catching or spreading HPV. Vaccines can
protect against several types of HPV, including some that can cause cancer2.
