The Associated Press reports on a Center for Disease Control study found that one in four teen girls have at least one STD.  Human papillomaviruses, the virus that can cause cervical cancer, was found to be the most prevalent STD.  Nearly half of the black teenagers studied had at least one STD.

A virus that causes cervical cancer is by far the most common sexually transmitted infection in teen girls aged 14 to 19, while the highest overall prevalence is among black girls - nearly half the blacks studied had at least one STD. That rate compared with 20 percent among both whites and Mexican-American teens, the study from the federal Centers for Disease Control and Prevention found.

About half of the girls acknowledged ever having sex; among them, the rate was 40 percent. While some teens define sex as only intercourse, other types of intimate behavior including oral sex can spread some infections.

Something is not working in American sex education.  My bet is on abstinence-only programs.
