Chlamydia
Chlamydial infections, the most common of all STIs, can affect both men and women. They may cause an abnormal genital discharge and burning with urination. In women, untreated chlamydial infection may lead to pelvic inflammatory disease (PID). Chlamydial infections can be treated with antibiotic therapy. Unfortunately, many people with chlamydial infection have few or no symptoms of infection. The most common and serious complications occur in women and include pelvic inflammatory disease, ectopic (tubal) pregnancy, and infertility.
