Chlamydia, often misspelt Clamidia, is one of the most commonly reported bacterial sexually transmitted diseases (STDs). Global chlamydia statistics show that an estimated 92 million new chlamydia infections occur each year, affecting more women (50 million) than men (42 million).
Chlamydia is caused by the bacterium chlamydia trachomatis. This bacteria can infect the cervix in women and the urethra and rectum in both men and women. Occasionally chlamydia can also affect other parts of the body, including the throat and eyes.
Chlamydia often has no symptoms, especially among women. If left untreated, chlamydia can cause serious problems later in life.
