What Is Chlamydia?
Chlamydia, which strikes about 3 million Americans a year, is the most common bacterial sexually transmitted disease in the U.S. Epidemiologists believe it's twice as common as gonorrhea, six times as common as genital herpes, and 30 times as common as syphilis.
The good news is that chlamydia is easily cured by antibiotics. The bad news is that 75% of women who contract the disease don't know they are infected until they develop serious complications such as damage to the fallopian tubes (the tubes that connect the ovaries to the uterus) causing pelvic inflammatory disease, which strikes 500,000 women a year and may result in sterility. Untreated chlamydia infection can also increase the risk of ectopic pregnancy (when the fertilized egg implants outside of the uterus) and premature birth.
The infection can also be passed on to an unborn child and cause serious complications. Each year in the U.S., 180,000 babies born to infected mothers suffer from pneumonia or conjunctivitis, an inflammation of membranes in the eye that may lead to blindness.
Fifty percent of infected men also have no symptoms. They may develop epididymitis, an inflammation of the male sexual organs that can cause sterility. Men can develop discharge from their penis or burning on urination.
What Causes Chlamydia?
Chlamydia is caused by the bacterium Chlamydia trachomatis. The disease is spread by oral, vaginal, or anal sex, and if you touch your eyes with a contaminated hand, you may also develop conjunctivitis. Chlamydia can be passed during vaginal birth to the infant. There is some evidence to support that untreated chlamydial infections in pregnancy can lead to premature delivery.
