Fact sheet - Health conditions directory

Chlamydia (Chlamydia trachomatis) is a bacterium that causes a sexually transmissible infection (STI). It most commonly affects the urethra (the delicate tube that runs from your bladder), the throat and the anus. In women it may spread to the cervix (neck of the womb) and the uterus. Chlamydia can also be transferred to the eyes through rubbing or touching with unwashed hands.
