About 10 percent of black women were reported to have chlamydia in 2007, but officials believe that only represents about half of the actual cases among that demographic group.

Astonishing racial discrepancies were found for both men and women among America's minority populations, and for women in general.
Officials think some of the differences arise because people from lower socioeconomic groups don't typically have access to routine, high-quality medical care.
