The Centers for Disease Control has released alarming statistics about teenage girls and sexually transmitted diseases.
It found more than three million teen girls are infected with an STD.
At least one in four teenage girls in the U.S. has a sexually transmitted disease.
By far, the most common infection is the HPV, or Human Papilloma Virus, which can cause cervical cancer.
Almost 20 percent of girls in the study, aged 14 to 19, have HPV.
Doctors say, at that age, many don't understand the long-term implications of an STD.
"Its kinda surprising because I'm that age too. But if you're gonna have sex, at least be safe," says Rosalynd Leal, 14, Pueblo Junior High Student.
Parents, as well as many in the medical community, believe screening, vaccination, and other preventative measures should fall among the highest public health priorities. A controversial vaccine for teens, targeting HPV, recently became available.
