Transmission of HPV strains is often the result of sexual contact, but it can also occur as the result of any skin-to-skin contact involving the mouth or genitals. Detectable warts can be or removed, usually by chemicals, freezing, or laser, but often recur. Intralesional alpha interferon has been effective in the treatment of genital warts. A vaccine approved by the Food and Drug Administration in 2006 can protect a woman against those strains that cause most cases of cervical cancer and genital warts, and a study has shown it may also protect against related throat cancers. HPV vaccination is now recommended for both girls and boys beginning at 11 to 12 years of age.
