The rates of three major sexually transmitted diseases in the United States in 2007 continued to follow a nearly decade-long climb that has disproportionately affected minorities and women, according to a report from the Centers for Disease Control and Prevention.
These trends in infection rates of chlamydia, gonorrhea, and syphilis are "not new, but the fact that they are continuing at such a dramatic level is really the major area of concern," said Dr. John M. Douglas Jr., director of the division of STD prevention at the CDC. All three STDs have long-standing federally funded control programs.
The report was compiled from surveillance data obtained from case reports from state and local STD programs, which included Regional Infertility Prevention Projects, the National Job Training Program, the Corrections STD Prevalence Monitoring Project, the Indian Health Service, and the Men Who Have Sex With Men (MSM) Prevalence Monitoring Project; the Gonococcal Isolate Surveillance Project; and national surveys implemented by both federal and private organizations.
Chlamydia
Since 1994, Chlamydia trachomatis infections have accounted for the greatest percentage of all STDs reported to the CDC. This trend continued in 2007, with more than 1.1 million sexually transmitted cases of chlamydia reported to the CDC, making it the "most commonly reported notifiable [infectious] disease in the United States," the report said.
Chlamydia infections rose 7.5% from 344 cases per 100,000 population in 2006 to 370 cases per 100,000 in 2007. This rate was roughly equal across the West, Midwest, South, and Northeast.
Chlamydia screening has grown since the late 1980s, especially in women, who are targeted for screening more often because of the risk of pelvic inflammatory disease (PID)--a major case of infertility, ectopic pregnancy, and chronic pelvic pain--and the passage of the infection to infants during delivery, which can result in neonatal ophthalmia and pneumonia.
