1 in 4 teen girls have an STD?

I must turn your attention to Matthew Archibold's (Creative Minority Report) coverage of a National Journal article that seeks to clear up some things about the recent CDC (Centers for Disease Control) finding reported in newspapers all over the country that 1 in 4 teenage girls have an STD.

This study which to me, a resident of Long Island, screamed out for abstinence education (which has not been federally funded on Long Island for 30 years) in our schools. Apparently, some on the other side of the fence took this to mean that abstinence education is not working. To which I reply - um, where is abstinence ed. being taught... because I certainly didn't receive it when I was in high school 8 years ago. Even so, I'll never understand the logic behind "have sex, so that you don't get a sexually transmitted disease". But then again, there are still teachers telling students that condoms are 99% effective when they've been proven to be 85% at most (for HIV) and 50% effective against others (Chlamydia, Gonorrhea, Genital Herpes, HPV [perhaps]) .
