Chlamydia is a sexually transmissible infection (STI) caused by bacteria called Chlamydia trachomatis. Many people who are infected with the bacteria do not have symptoms but can still transmit it.

Chlamydia can affect the urethra (the urine passage), cervix (the neck of the womb), rectum, anus, throat, and eyes.

If chlamydia is not properly treated it can cause serious complications, including infertility (inability to get pregnant) and recurrent urethritis in men.

How far back in time should you trace your previous partners? 6 months.
