ATLANTA, July 16 (UPI) -- About 1 million U.S. adolescents and young adults ages 10-24 reported having chlamydia, gonorrhea or syphilis in 2006, health officials said.
Nearly one-quarter of females aged 15-19 years and 45 percent of those ages 20-24 years had a human papillomavirus infection during 2003-2004, the Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report said.
CDC analyzed data from 2002-2007 from the National Vital Statistics System and data from multiple sources.
The report said there were approximately 745,000 pregnancies among U.S. females under age 20 in 2004. In 2006, the majority of new diagnoses of human immunodeficiency virus infection among adolescents and young adults between the ages of 10-24 occurred among those ages 20-24 and among males.
Some 100,000 females ages 10-24 were treated in a hospital emergency department for a non-fatal sexual assault injury during 2004-2006, the report said.
