Chlamydia trachomatis infection in women: bad news, good news, and next steps in prevention.

Chlamydia trachomatis causes largely asymptomatic infections that can lead to pelvic inflammatory disease, infertility, ectopic pregnancy, and chronic pelvic pain. Screening women routinely is critical to controlling the epidemic of this disease. Testing innovations now make diagnosis easier, and simple treatment regimens may improve compliance with medications and increase cure rates, but testing and treatment must be coupled with improved screening efforts and effective partner services. Ongoing research may point to other interventions that will increase our success in fighting chlamydial infections.
