These new data were presented at the 16th biennial meeting of the International Society for Sexually Transmitted Diseases Research (ISSTDR), July 10-13, in Amsterdam.


"STDs often have no symptoms and therefore frequently go unrecognized and undiagnosed," said Dr. John Douglas, director of CDC's STD prevention programs. "Stepping up screening and prevention efforts is critical to ensuring that young people do not suffer the long-term effects of untreated chlamydia, including infertility."

In the first nationally representative study of chlamydia prevalence in the general adult population (ages 14-39), CDC researchers found a chlamydia prevalence of 2.2 percent and no significant differences between women and men overall. Nearly 1 in 20 women between the ages of 14-19 (4.6 percent) were infected
