Chlamydia can refer to a particular group of bacteria which cause a variety of diseases (see related question "What are chlamydiae?"), but usually chlamydia refers to the sexually transmitted disease caused by Chlamydia trachomatis.
Chlamydia is a common sexually transmitted disease affecting 1.4 million Americans each year. Many men and 80-90% of women with chlamydia have no symptoms. Even though symptoms of chlamydia are usually mild or absent, the infection can cause serious complications including irreversible damage that can make it hard to get pregnant later. These complications can can occur "silently" before a patient ever recognizes a problem.
Symptoms in men can include painful urination and discharge from the penis. In women, there could be painful urination, an unusual vaginal discharge, bleeding after sex or between periods, or abdominal pain.
Only a health care provider can diagnose chlamydia (through laboratory tests). Laboratory testing is especially important, since the symptoms of chlamydia, if there are any at all, closely resemble those of other STDs (like gonorrhea), and those of other types of infections (like urinary tract infections).
Chlamydia testing is painless, and can be done on a urine sample. Chlamydia is curable with certain types of antibiotics. There is no immunity against chlamydia, so you can get this infection again and again if re-exposed.
If you think you have a sexually transmitted disease, contact your health care provider or a local health clinic.
