Almost can't believe, but this is the result found from the study done by the federal Centers for Disease Control and Prevention in Atlanta!
One in four teenage girls in the United States has a sexually-transmitted disease, a study has indicated.
The study, by the federal Centers for Disease Control and Prevention (CDC), found an even higher prevalence of STDs among black girls.
Researchers analysed data from a nationally representative sample of 838 US girls aged 14 to 19.
A virus that causes cervical cancer - HPV - was the most common, followed by chlamydia, trichomoniasis and herpes.
The CDC says the study is the first in its kind to examine the prevalence of common sexually transmitted diseases among adolescent girls.
It found that nearly half of the African-American girls surveyed had at least one STD, while the rate was 20% among white and Mexican-American teenagers.
Human papillomavirus, or HPV, affected 18% of the girls surveyed, chlamydia 4%, trichomoniasis 2.5%, and herpes simplex virus 2%.
