According to the CDC, "the reported rates of chlamydia and gonorrhea are highest among females aged 15-19 years, and many persons acquire HPV infection during their adolescent years." Over 50 percent of sexually active people will get human papillomavirus (HPV) at some point in their lives, and the STI can be transmitted even with condoms. There are more than 40 different types. Two human papillomavirus (HPV) vaccines are available for females ages 9-26 to prevent cervical pre-cancer and cancer (15,16) and HPV: Gardasil and Cervarix.
