Chlamydia is the most common bacterial STI in the United States. The bacteria Chlamydia trachomatis causes the infection. Women with an infection may experience abnormal vaginal discharge, bleeding after sex, or burning with urination. Many women experience no symptoms. An untreated chlamydia infection can lead to complications such as pelvic inflammatory disease (PID), ectopic pregnancy (a pregnancy outside of the uterus), and infertility.
All pregnant women should be tested for chlamydia with the nucleic acid amplification test (NAAT). The test may be done using a urine sample. Chlamydia can be treated with appropriate oral antibiotics. Untreated chlamydia infection in pregnant women has been associated with miscarriages, low birth weight (infant being born weighing less than 5-pounds 8-ounces), and premature (early) birth. A newborn may become infected as it passes through the birth canal. Mother-to-child transmission of chlamydia can cause pneumonia and serious eye infections that may lead to blindness.
